I need to do below things with Pi :-
Convert to Bluetooth Keyboard
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 :
Remarks: Support HID and HFP .Few threads says that Broadcom chips are bad for Pi
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
