I have ARM based board, kernel 4.14.67 and bluez-4.101. I want to connect bluetooth headset for playing sound from the board. My question is similar to that: https://stackoverflow.com/questions/36295784/bluez-4-101-on-embedded-arm-device
I try to do the following:
1) make a file named .asoundrc in home directory
2) hciconfig hci0 up piscan
3) bluetoothd -d -n (how to make debug output more verbose?? It prints just a small amount of info)
4) sdptool add hs - Is this enables Headset profile?
5) power on headset and enter pairable mode on it
6) hcitool cc 00:1C:EF:9F:86:BC - try to connect to headset, there is no any output from the command and I don't know is it successful or not?
7) then I immediately call hcitool con and see
Connections:
< ACL 00:1C:EF:9F:86:BC handle 43 state 1 lm MASTER
but a few seconds later subsequent call of hcitool con returns nothing connected.
No debug output in dmesg or from bluetoothd seen. What may be the reason of connection goes down?
8) Try to play aplay -D btheadset ./testsound.wav, but it failed:
bt_audio_service_open: connect() failed: Connection refused (111)
aplay: main:722: audio open error: Connection refused
