I am working on a project that allow me to control a robot, using rpi, in bluetooth. I have a lot worked on bluetooth and I all work fine in android.

But in iOS it's ... very strange...

I transformed my raspberry into a iBeacon and with an application like Locate (iBeacon) I can see it. I have sucessfully paired my rpi with my iPhone using this tutorial : http://www.wolfteck.com/projects/raspi/iphone/

But even if the rpi is paired it is not visible in bluetooth setting, bluetooth terminal application like (BluTerm and BluetoothLE) and on my cross platform ionic-cordova app using this plugin: don/BluetoothSerial.

To be clear:

what I have:

  • rpi 2 and this bluetooth module: http://plugable.com/products/usb-bt4le
  • Bluez 5.11 installed
  • All bluetooth serial communication working on android
  • Raspberry and iPhone(ios 8.2) paired together. The pairing request from the rpi because ios bluetooth settings don't see my raspberry.
  • Raspberry transformed in beacon and visible with locate app.

What I want:

  • raspberry visible in bluetooth setting/ bluetooth terminal application like (BluTerm and BluetoothLE). Because my cross platform app use the native scan system and terminal like communication.

Some settings :

pi@raspberrypi $ hciconfig hci0 -a

Bluetooth Serial Modules like HC-05 and HC-06 might interest you. These modules connect through the UART pins (6,8,10) and provide terminal access via the Blueterm.

Your statement "terminal like communication" led me to think terminal access via bluetooth. Hence my suggestion. I do have a HC05 (and HC06) that i use to get console access.

  • No. You won't be able to use a classic bluetooth module with an iDevice unless it is MFI certified, which the HC-05/HC-06 are not.

  • Hi Chris, I read a little on MFI certified device, there is a way to do it simply for test without company and apple contact ?

  • Hi Vittal, thanks for your answer. Are you sur about HC-05/06 and iPhone connection ? Have you a link to a working project or tutorial?

If it's not visible in your scanning turn Bluetooth advertising ON with:

sudo hciconfig hci0 leadv

  • Hi HallMark, thank you for the answer even if the project is finish now (I just don't use iOS). Bluetooth advertising was ON. Android device could see my device so advertising was on.

  • @AdrienRobotLabo: You have used RFCOMM or L2CAP on Raspberry Pi side to get it working with Android?

  • I have used RFCOMM from command line and pybluez (don't know which protocol pybluez use) from programming.
