I need to do below things with Pi :-

  1. Convert to Bluetooth Keyboard

  2. Need to pair with my smartphone to Reject all Call and accept only whitelisted call.

I am sure I need to use HID and HFP profiles but problem is selection of compatible Bluetooth USB dongle.

I came across few usb as below :

  1. http://plugable.com/products/usb-bt4le
    Remarks: Support HID and HFP .Few threads says that Broadcom chips are bad for Pi

  2. CSR 4.0 Remarks: Cannot identify which all profiles are there. I need a help here to identify which all profile are supported.

Please help me .Advance thanks

  • Be careful with Bluetooth keyboards, I've had numerous problems with stuck keys and others. – C Malasadas Apr 1 '17 at 3:11

  • Ah, I thought you were talking about using a Bluetooth keyboard for your Pi, my bad. – C Malasadas Apr 1 '17 at 11:53
  • No. I made Pi as Keyboard. Here , Pi is loaded with HID Device profile . – ABHIJITH KINI Apr 1 '17 at 12:53

The Plugable USB Bluetooth Dongle (Plugable support team doesn't know this .I had once contacted them to know feasibility but they gave a negative response ) works to turn Pi as Keyboard. I installed BlueZ 5 and load HID profile with help Python package called pybluez .It worked.
