I’ve tried some ways to make BT work well, but it didn’t work out.
here is my menuconfig, I almost enable all drivers:
I tried rfcomm, and when I use rfcomm to connect my phone, my phone is also giving a respose to me. but it need pair pin code, I tried many ways to set pin code, but I failed.
I also tried bluetoothctl, it could config pair pin code, but it says no default controller available.
is there anybody have idea?
