iBeacon

24 07 2014

Aeronautical beacons are well-known but the only relation to my topic is that the communication between Apple’s iBeacons and mobile devices also works over the air, not in the visible frequency spectrum of electromagnetic waves but in the invisible near frequency spectrum.

About waves …

Your iOS devices are nothing without waves.

Waves are the food for every mobile device connected to the internet, your carrier, or an iBeacon and contain the information e.g. needed for your browser to show websites, for a phone call to transmit your voice, and for an iBeacon connection to exchange data if you are near to it.

You all know water waves, seismic waves and waves that transmit the sound from one person to another or from speakers to your ear. Sometimes sound waves contain good news or bad news. Whatever is transmitted by waves it’s always INFORMATION.

In case of iPhones contacting your carrier or iPads contacting your wireless access point, waves are Electromagnetic Waves. In contrast to water waves (propagating through water), the sound (propagating through gas) and seismic waves (propagating through the earth) electromagnetic waves don’t need a medium. They also can carry information while propagating through the vacuum with the speed of light (about 300.000 m/sec). That’s pretty fast and helps when transmitting information to your device because there are many disturbers around us and so information has to be transmitted several times before being identified as those destined for you.

Look here for waves in motion

Simple Wikipedia

Properties of waves are among others the amplitude (height of cycles) and the frequency (number of cycles per second). Sound waves have a low frequency when we hear a deep tone. The frequency is measured in Hertz (Hz).

Image (1) shows an AM (amplitude modulated) wave and Image (2) an FM (frequency modulated) wave. You all know AM and FM if you ever looked on a radio’s dashboard. The more important method is to transmit information with a frequency modulated wave.

In an area of interference signals may be extinguished due to the fact that a wave peak may meet a wave trough.

About iBeacons …

iBeacon is Apple’s name for a technology that allows mobile apps to know how close they are to tiny, low-cost, wireless transmitters called hardware iBeacons.
iBeacons technology isn’t a development of Apple. Many recent Android devices already support it. iBeacons broadcast signals using the well-known Bluetooth Low Energy (BLE) standard, allowing precise, indoor geo-location (often called ‘Micro- location’) where smartphones or tablets are not able to receive GPS signals from satellites, but also contextual interaction and engagement, as proximity to an iBeacon can trigger some specific app functionalities or even launch an app.

Bluetooth low energy, Bluetooth LE, or BLE, marketed as Bluetooth Smart, is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, security, and home entertainment industries. Compared to “Classic” Bluetooth, BLE is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range.
Bluetooth LE was originally introduced under the name Wibree by Nokia in 2006. It was merged into the main Bluetooth standard in 2010 with the adoption of the Bluetooth Core Specification Version 4.0.
Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as OS X and Windows 8, natively support Bluetooth low energy. The Bluetooth SIG predicts more than 90 percent of Bluetooth-enabled smartphones will support the low energy standard by 2018.

iBeacon-enabled apps are notified when the device moves in and out of the range of iBeacons. They monitor the distance as their proximity changes over time. This allows apps to know precisely where they are not in terms of a map but relative to known points within a building.

20140409-165835.jpg

iBeacons are tiny battery-operated radio signal stations you can place wherever you want. If your mobile device gets within range, it senses iBeacons and locates itself.
iBeacons broadcast a “I am here!” message (approximately once per second) to any device within range of the Bluetooth Low Energy radio signal; since each iBeacon has its own ID, the mobile device can tell them apart and recognize the context of the world around itself.
iBeacons usually just identify themselves by an ID but do not transfer other data than this.

Micro-locating a device can initiate interaction, engagement, and contextual information. Mobile apps receiving signals of iBeacons can be triggered triggered to perform a specific action on a specific mobile device at a specific time and in a specific location.

Summarized, iBeacon signals can

  • precisely locate you within a building
  • triangulate constantly and quietly in the background
    When you pull out your phone, the right content is there waiting for you. This immediacy is one big advantage Bluetooth now has over clunky predecessors like NFC and QR codes.
  • make suggestions what you can do with the help of an iBeacon capable app

iBeacons therefore make it possible to seamlessly engage with people in a physical space through their mobile devices.

Some examples …

Contextualized deals
iBeacons technology allows to convey specific, customized deals to shoppers based on time and day, their purchase history, their loyalty, etc. Think of very customized offers; for example a shopper has checked an item in a store but did not purchase it. The retailer then can offer the shopper a discount via email or directly on the mobile device the next time he enters the same store (or an other chain store).

Monitoring shoppers behavior
Monitoring shoppers behavior (store visits, walking-paths, etc.) is another possibility. With the help of an iBeacons the retailer may get the information (in real-time) that the shopper has been standing in front of one specific display for more than three minutes; sensing second-by-second a shopper’s (inferred) interest about a specific product, the system can supply additional information such as online reviews and – talking about fashion – other available styles or colours. As you go on shopping, a blue tie might (metaphorically) tell you: “I’m perfect with the gray suit you purchased here last week”.

This is one side of a coin and this application of iBeacons might be nerve-racking for many of us who already suffer from the constant onslaught of ad on TV, on websites, and nearly all other areas of live.

So let’s have a look on the coin’s backside.

In developed countries with public health care the emphasis on personal responsibility has been the best way to both reduce costs and make the system more efficient. In America you have to go through the gauntlet of health care providers and insurance providers and pharmaceutical companies to take charge of your own good health. If Apple’s iBeacon software is installed in the next ambulance to arrive at my home then an iPhone might light up with your emergency information automatically once you are inside the vehicle. You might not even be conscious. But your iPhone can give them what they need to know to start treating you. The device might also tell them you have had high blood pressure for the past six weeks and rising. All this with a personal tracking iWatch and the M7 motion processor on the iPhone.

To emphasize the more useful applications of the iBeacon technology let me another example.

You are walking through a museum of art, iBeacon micro-locates you and provides information about the artist of an artwork you are looking at.

It would be no problem to write further 10 blogs about possible applications of this technology. It’s up to the creativity to find out nearly unlimited further applications.

The crux is that a new operating system provides an option – like for Location Services – to turn off the bit radiation which might affect our health. The two communicating devices, the iBeacon and the iPhone – shouldn’t get control over our most important processor, our brain.

Platforms …

The great news about iBeacons technology is that both Apple (with iOS and OS X) and Google (with Android) have committed to support for Bluetooth LE – this means very, very broad availability (literally millions of devices are already iBeacon-enabled) and there is no danger of launching services targeted at a single operating system.

What about Microsoft?

Microsoft appears to have recently added support for Bluetooth Low Energy in Windows 8 and Windows Phone 8; Nokia’s recent Lumia WP8 phones are confirmed to include BLE hardware.

Some technical details …

An iBeacon identifies itself using three customizable values

  • Proximity UUID (128 Bit)
  • Major (16 Bit)
  • Minor (16 Bit)

So there are three levels to identify a micro-location: only Proximity UUID, Proximity UUID and Major, Proximity UUID and Major and Minor.

For example

  • Proximity UUID identifies your entire retail company, Major identifies a specific store and Minor specify individual shelves or different checkout tills inside each store.
  • Proximity UUID identifies your museum, Major identifies a specific gallery within the museum and Minor identifies an exhibit within that gallery.

The radio signals of iBeacons allow to calculate distances in qualitative

  • Immediate
    (less than 50 cm)
  • Near
    (approximately 50 cm to 2-5 m)
  • Far
    (more or less between 50 cm and 30-50 m, depending on walls, the iBeacon output power, and many other factors like interference)

Bluetooth low energy is not backward-compatible with the previous, often called Classic, Bluetooth protocol. The Bluetooth 4.0 specification permits devices to implement either or both of the LE and Classic systems. Those that implement both are known as Bluetooth 4.0 dual-mode devices.

Bluetooth LE uses the same 2.4 GHz radio frequencies as Classic Bluetooth, which allows dual-mode devices to share a single radio antenna. LE does, however, use a simpler modulation system.

iBeacon vs NFC vs QR-Codes …

I think we must not talk about QR-Codes which are powerful for industrial production but not accepted as a relevant source of information by the majority of people. Admittedly we might find QR-Codes on boxes containing iBeacons or NFC Tags.

Since Apple’s 2013 announcement, the press has been praising iBeacon for its ability to passively identify the in-venue presence of smartphone-equipped consumers. They have also been praising it for its ability to passively notify and then subsequently deliver localized information. These features, along with the press’ embrace of iBeacon’s perceived ease-of-use, location services, energy efficiency, security and low cost, have made iBeacon the sweetheart of the tech industry.

Since the press’ enthusiasm for iBeacon has gone largely unchallenged, many have taken the liberty to label NFC as irrelevant because it lacks iBeacon-like features. But, is this the truth?

20140410-163806.jpg

Although the NFC environment is very different and has many non-overlapping applications, it is still compared with iBeacons.

  • NFC range is up to 20 cm (7.87 inches) but the optimal range is < 4 cm (1.57 inches). iBeacons have a significantly larger range.
  • NFC can be either passive or active. When using passive mode, the power is sent from the reader device as radio signals. Whereas although Passif (a company acquired by Apple) has worked on reducing the energy consumption, a battery pack is still needed inside iBeacon tags at this time.
  • Most smartphones ship with both Bluetooth 4.0 LE and NFC support but at this time, no iOS device has been released with NFC support.
  • A BLE beacon is great for passively enabling a retailer’s mobile app to deliver promotions, coupons or offers direct to the consumer’s smartphone when the consumer is in the general vicinity. NFC can’t do that. But if you want to research a specific Nikon SLR, for example, you can scan an NFC-enabled shelf tag next to it and study to your heart’s content. BLE can’t deliver that much location granularity.

So the final conclusion is:

iBeacon is the much more powerful technique mainly because of it’s range and automated communication.

Advocates of the NFC technology might argue with the lower costs of NFC tags (about 0.5$) compared to iBeacons (about 25$). But because of the limited range you need far more NFC tags distributed e.g. in a retail store (approximate price Apr 2014).

iBeacon demo …

Here is a video showing iBeacons in action.
It was published on December 10, 2013 by InnoQuant, an advanced analytics software company founded in Barcelona in 2010. InnoQuant provides data analytics services and software solutions to solve problems of Big Data Analytics such as real-time mobile marketing.
InnoQuant technology allows users to monitor, analyze and engage their customers via mobile apps providing strategic tools for their business.

Summary …

iBeacon technology is extremely powerful and flexible, so engineers, marketers, and others have the opportunity to create new important applications to improve people’s lives and to create business value for big and small companies. But don’t worry about the innovative new big brother. Instead of crying ‘Stop bothering me!’ just turn Bluetooth off.

I’m sure that apps of serious retailers will offer some options to choose the kind of information you want to receive. If not they are at risk that customers will delete the app, block information flow, or in a worst case scenario, say Good Riddance to the company.

Photo Syncing

30 07 2013

iOS devices are frequently used to take photos of objects or documents.
If iCloud is turned on photos are automatically synced across all iOS devices using the same Apple ID in the so-called Photostream.

A direct transfer of photos from the camera roll or the photostream to an external storage or another device using a different Apple ID is not possible.

Sharing photos via Apple’s Photostream (by E-Mail) is followed by substantial loss of quality. Sharing via a cloud client is time-consuming and not recommended if the destination device is in the same WiFi network or can be connected to the source device via Bluetooth.

I have often wondered why Apple didn’t offer a seamless transfer from one iOS device to another. Regarding this point Apple did not follow it’s own strategy of seamless usage.

With iOS 7 Apple will eradicate this flaw by introducing AirDrop.

Sending a photo or a document to someone via text or email is fine. But if that someone is right next to you, a text or an email suddenly feels like too many steps. Enter AirDrop for iOS. It lets you quickly and easily share photos, videos, contacts — and anything else from any app with a Share button. Just tap Share, then select the person you want to share with. AirDrop does the rest using Wi-Fi and Bluetooth. No setup required. And transfers are encrypted, so what you share is highly secure.
(Apple on its website)

Unfortunately AirDrop is not available for previously supplied iPhone 4S, 4, etc. and iPad 3rd Generation, iPad 2, etc. So there will be still a need for an app which does the task seamlessly.

There is an app available in Apple’s App Store named PhotoSync (by German developer touchbyte GmbH) which offers many options to transfer photos wirelessly in a simple way with a perfect UI (user interface) as well as a perfect UX (user experience).

Just select multiple photos from the camera roll, photostream or self-created albums, select the destination device or cloud storage and you’re done. Sending will continue in the background – even if you receive phone calls or do other things with your device.
The maximum transfer rate is up about 2.5MB/s that means about 2-3 photos/s (depending on device and network).

20130521-160450.jpg

Using Bluetooth I transferred 23 images with total size of 17 MB within 81 s which is a transfer rate of o.21 MB/s compared to a transfer rate of 0.68 MB/s when using WiFi with an Apple Airport Extreme router.
So the maximum transfer announced by the developer is a dream.
Nevertheless it works fine and it’s much faster than any transfer via a cloud storage (device – cloud – device).

The main Features …

  • Transfer to
    allows transfer to Dropbox, Picasa/Google+, Facebook, SmugMug, 500px, Flickr, Box, Zenforio, (S)FTP, WebDAV, SykDrive, and Google Drive
  • Quick transfer
    allows to set a default computer (or other service) in the settings and then just transfer all new/selected pictures to this default computer/service by pressing and holding the sync button.
  • Direct transfer between iOS devices
    allows transfer from one iOS device to another with a different Apple ID if both devices are in the same WiFi network or Bluetooth is turned on.
  • Transfer to computer
    allows Wi-Fi access to your photos/videos wherever you are – from any computer on the same WiFi network by just opening a web-browser
  • Services
    supports transfer directions: Device to Computer (WiFi), Computer to Device (WiFi), Device to Device (WiFi + Bluetooth), Device to Web Services (WiFi + 3G + 4G)

20130727-231158.jpg

See this video with PhotoSync in action

UI impressions …

It’s always a good idea to see some screenshots before deciding to download an app from the App Store. There is still no way without stumbles to give an app back and get a refund if it’s not the right app or it has severe bugs.

The settings screen shows you some options as well as supported external storages.

20130521-163850.jpg

The running app shows that there is an understandable and informative feedback for users.

20130521-164004.jpg

iOS device to Android device …

PhotoSync is now available for Android devices. A step forward because if there is no computer available the only way to transfer photos between these galaxies is to use the Jacob’s ladder that means:
copy to cloud + share with recipient + download from cloud
That’s the price you have to pay when contacting extraterrestrial Androids.

NAS …

If you are fully integrated in the Apple hardware ecosystem you may own an Apple router like Airport Extreme. The APE has a USB port but unfortunately PhotoSync cannot communicate with an USB storage connected to the APE. This is called Network Attached Storage (NAS). So there is no chance to copy photos from your iOS devices to the USB storage.

The only way to do this is to install another app like FileBrowser by Stratospherix. Configure a new connection with the option TC (Time Capsule, Airport Extreme), enter the local IP address of this device as well as your username and password for WiFi access.
FileBrowser then allows copying photos from your iPad/iPhone to the attached storage.

Companion apps …

PhotoSync Companion for Mac OSX or Windows is a FREE utility to support the best transfer performance (unlimited number of images, background transfer, etc) for picture and video transfers from your iPhone, iPod Touch, or iPad to your Mac or Windows PC with the PhotoSync app.

Further information …

  • Supported transfer directions: Device to Computer (Wi-Fi), Computer to Device (Wi-Fi), Device to Device (Wi-Fi & Bluetooth)
  • All Exif data, GPS data, and file date is preserved for photos/videos in Camera Roll
  • Full support for RAW images and photos/videos imported with iPad Camera Connector
  • Requirements for FREE Mac-Companion: Mac OS X 10.5 or higher (Intel and PPC supported)
  • Requirements for FREE Windows-Companion: Windows XP SP 2 or higher, Windows Vista, Windows 7, Windows 8
  • Web-Browser-Access requires modern browsers with JavaScript-Support enabled
  • Transfer Rate up to 4 MB/sec (depending on device and network)

Notes …
In iOS 4 and iOS 5 location services must be enabled to use the application! In iOS 6 Apple changed the access to photos from ‘location services’ to ‘photos’.
For best transfer experience and performance, we recommend installation of the free PhotoSync Companion Software.
Supported wireless connection depends on transfer target: Bluetooth & Wi-Fi – transfer from iOS device to iOS Device; Wi-Fi – transfer from/to computer; Wi-Fi and 3G /LTE – transfer to web-services

A competitor …

There is another app for seamless transfer of photos from one iOS device to another available.
It’s Safety P+V by 83 Technology with the additional feature to protect use of the app and access to all photos and videos stored in the app’s local folder by entering a password.

Short-Haul Flight

3 05 2013

iOS Airways welcomes you on our flight from iPhone to iPad.
Please be sure your seat belts are fastened as our captain will go by the speed of light.
If you’re going to leave anything after touch down, please make sure it’s something we’d like to have.

The basic idea …

M2M or machine-to-machine communication, or technology that supports wired or wireless communication between devices. An example of M2M technology might be a set of devices that monitor traffic in a city and communicate the information to the city’s traffic lights in order to regulate the flow of traffic.
(http://searchnetworking.techtarget.com)

There are several ways to establish M2M for sending files from one device to another.

  • iOS device – Computer
    Using iTunes File Sharing or computer software like iExplorer which allows access to app specific folders on an iOS device
  • iOS device – Any device
    Send by E-Mail using Apple’s mail client
    A suitable app must be installed on the destination device to open attachments
  • Send to a cloud storage and share the file
    An app with the original file must support server access with built-in access for well-known providers WebDAV
  • iOS device to another own iOS device
    Transmit via iCloud
    Not all apps support iCloud at the time
    Access is only possible if both devices use the same Apple ID
  • iOS device NAS
    NAS (network attached storage) can be a computer’s hard disk or a hard disk or a USB storage attached to Apple’s Airport router or Time Capsule

Examples …

Here are some apps supporting direct transfer from one iOS device to another even if the destination device is running under a different Apple ID:

  • Tap Forms Database
    by Tap Zap Software, Inc.
    WiFi and Bluetooth
  • Safety P+V
    by 83Technology
    Bluetooth and WiFi
  • Safety Notes
    by 83Technology
    Bluetooth and WiFi
  • Phone Drive
    by 83Technology
    Bluetooth and WiFi
  • GoodReader
    by Goodiware
    WiFi
  • USB Disk Pro
    by Imesart
    Bluetooth and WiFi
  • Air Sharing
    by Avatron
    WiFi
  • Documents
    by Readdle
    WiFi
  • Instashare
    by Lukas Foldyna
    WiFi and Bluetooth

Transfer Methods …

  • WiFi and Bluetooth
    One device acts as a push server.
    Usually the destination device firstly has to accept the connection.
  • WebDAV support
    The iOS device acts as a WebDAV server for a computer.
    On the computer you access the device by entering an URL like
    http://10.0.1.3:8080 (IP address of the iOS device and Portnumber for communication).

Establishing connections …

This description is valid for Phone Drive by 83Technology and explains the different connection methods.

File transfer between Mac or PC

Connect your device to same Wi-Fi network with PC or Mac.
Tap “Sync” icon and select “Mac / PC File Transfer” button to find out your device address.
Web Browser
Enter the IP address on your computer web browser to access file transfer interface.

Mac OS X

Open Finder.
Select “Connect to Server” from the “Go” menu.
Enter the IP address and click “Connect”.
Note : If you do not enable Authentication just select “Guest” and click “Connect”.

Windows

From My Computer click on the “Map Network Drive” toolbar button.
Enter the IP address and click “Finish”.

File operations
Click on “Edit” button or swipe right and select the file you wish to perform operations.
Tap on “Menu view” icon to choose file operations. (Copy, Move, Zip, etc)

File sharing to another iPhone or iPad (Bluetooth / Wi-Fi)

Connect both devices to same Wi-Fi network or enable bluetooth.
On of the device tap on “Sync” icon and select “iOS to iOS File Sharing” button to search for nearest device.
Select the device name that found and accept connection for file transfer.

The UIs of assorted apps …

Rate the developer’s approaches to UIs for transferring files.

Instashare …

Instashare is an aptly named utility that lets you instantly share files between your iOS devices and your Mac and Windows PC (Beta).

Sharing is quite simple. Open the app on both iOS devices.
On a device all connectable other devices appear on the right side and the file list on the left side. You transfer files by Drag and Drop from left to right.

Instashare uses WiFi or Bluetooth. An Internet connection is not required.

In addition, you can transfer files of any file type from a Mac to your iDevice, and vice versa. Files received by a Mac appear on the Downloads folder, while those received by an iOS device can be found in Instashare’s local app folder.

20130502-204138.jpg

Public Wi-Fi …

Sometimes, when using public WiFi for transfering files, problems might occur when starting the file transfer or displaying the list of nearby devices. Instashare is using ports 1000 and higher but public WiFi’s (Coffee shops, Airports, …) may block these ports. Best practice to settle this problem is creating your own WiFi access point which in iOS terms is called ‘Personal Hotspot’.

Personal Hotspot
A Personal Hotspot is one of your iOS devices with a connection to the internet.
This device may act as an access point for an other device that means, the other device does not connect to the internet directly but via the device serving as Personal Hotspot.

Go to Settings – Personal Hotspot and turn the switch to ON.
With your other device you now can connect to the Personal Hotspot in the same way you would connect to any other WiFi network.

Summary …

Instashare is the winner when it comes to a rating of the UI.
Simplicity and intuitive handling is the key to a top rating.

Transfer is only supported for one file at a time.
Selection of multiple files should be offered in an upcoming feature update.

Note (2013-05-02)
At the time I wrote this article PDFs could not be transferred from other apps to Instashare by using the ‘Open in’ command. But this problem was settled by Lukas. So now it works. Thanks Lukas.

Summary …

I myself use the mentioned apps and assessed them all very critically.
Tablets are a new technology (first iPad came in 2007). While the hardware is already grown up the software is still embryonic. Apple’s App Store makes no difference between hobby and professional developers. So for customers it’s not easy to find out the right app. And there is a further problem: the reliability of a developer, the power to refine the product and the energy to survive in the fast growing market of rock-bottom goods.

Most of the users working on an iPad without it’s big brother perceive the desirable features an app should have. But it seems to me that most of the developers are not able to adjust to the market.

Please comment on this blog.
Both, positive and negative comments are welcome.





Device To Device Transfer

10 03 2013

Why should I transfer my data over thousands of miles using an internet connection although my devices are only a couple of inch apart!

Normally nobody takes care of an efficient transfer method but sometimes there is no WiFi or Cellular connection. In this case you cannot transfer data from one iOS device to another except you use iTunes on your computer. That’s certainly not comfortable.

Connections between two devices in general can be established via WiFi, an internet connection (e.g. syncing via iCloud) or a connection method called Bluetooth (henceforth referred to as BT).


Wikipedia
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

While most people think of BT as the way that wireless earpieces get connect to phones, it’s actually a more general purpose technology that allows many kinds of devices to be used.

This post will give you some detailed information about BT and its application from within BT capable apps.

Turning on Bluetooth …

Complete this procedure to connect with accessories for iPad/iPhone e.g. BT Keyboard or BT Headset:

http://ipod.about.com/od/iphonehowtos/a/Iphone-Bluetooth-Pairing.htm

The process of connecting a BT device to an iPhone is called PAIRING. Regardless of what kind of device you’re pairing to your iPhone, the process is basically the same. Follow these steps to complete the iPhone/iPad BT pairing process.

Begin by making sure your iPhone and BT device are near each other. BT signals can only extend a few feet.
Next, put the BT device you want to pair with the iPhone in discoverable mode. This allows the iPhone to see the device and connect to it. Making a device discoverable requires different steps on different devices. For some it’s as easy as turning them on, for check the manual.
Go to Settings, tap BT and turn it on. A list of all the discoverable BT devices will appear.
If the device you want to pair with is listed, tap it.
To pair some BT devices with the iPhone, you need to enter a passcode. If the device you’re trying to pair is one of those, the passcode screen will appear. Consult the device’s manual for the passcode and enter it.

Keep in mind that BT is a short-range connection (distances up to 164 feet/50 meters) and will be lost if you move the connected devices too far apart.

While BT doesn’t drain as much battery as Wi-Fi, keep it turned off when not in use.

Using Bluetooth …

You cannot pair iPhone and iPad.
Nevertheless BT can be used for the ‘Personal Hotspot‘ feature for providing an internet connection for iPad via the cellular connection of an iPhone or vice versa.

Even if you could pair these devices you wouldn’t have any benefit because there are no apps provided by Apple (Photos, iWork, iMovie, Calendar, etc.) which support data transfer via BT.
I may be wrong but that could be the reason why pairing of two iOS devices makes no sense from Apple’s point of view. Anyway, a programming interface is available so that app developers are able to support BT if needed.

Applications using BT …

These apps for example support BT:

Safety P+V (Photos management)
Safety Notes (Notes management)
Phone Drive (File Management)
Wireless Drive (File Management)

How it works …

Let’s have a look on Safety P+V by 83Technology, an app with a perfect UI.
This app is for managing photos and videos in folders which can be created by the user. You additionally may define a password to secure the data. Further features are:
transfer photos from and to the camera roll
move photos and videos from one folder to another
print photos and open them in another app

Here is a description how to transfer photos or videos between two iOS devices.

Note
On both devices WiFi is turned OFF and BT is turned ON.
The devices must NOT BE PAIRED.

  • Open open SAFETY P+V on both devices.
  • Tap the Sync icon on the device which is the sender.
  • Select iOS Wi-Fi / Bluetooth Transfer. The other device is then listed under ‘Devices nearby’.
  • Select the objects you want to transfer and tap on Send.

20130121-151032.jpg

The selected files are transferred into the ‘Image Sharing’ folder from where you can move them into other folders.

Other apps supporting BT …

There are some other apps available in Apple’s App Store supporting a BT connection between two iOS devices. But on my point of view all these apps make no sense.
Why? Consider the following situation:

You want to transfer an iWork document to another device.
If an internet connection is available the best way is to use iCloud as the documents are synced automatically. If there is no Internet and no WiFi connection available you have to firstly transfer the document to the local folder of the BT supporting app via ‘Open In’. Then the file must be transferred from the BT supporting apps local folder via ‘Open In’ to the iWork app.

My rating: ZERO STARS FOR USABILITY

Summary …

BT is a reliable, powerful, fast and secure wireless technology for data transfer with minimized power consumption. Apple’s BT implementation on iOS devices is mostly incompatible with smartphones or tablets from other vendors.
For some inexplicable reason it’s not available as a standard feature for data transfer between iOS devices.

Thanks for reading my post.
