I am having trouble trying to pair my bluetooth speaker to the ci20. It can detect the bluetooth speaker, and will connect first time I pair it but drops off after 2 seconds. I then try to reconnect to it but get a
Connection Failed: Nosuch file or directory
and this happens every time I try to reconnect.4th March 2017 at 10:12 am #63701
So I try to connect via command line to see what sort of error message I get and here is the output when using gatttool
/etc/pulse$ gatttool -b BC:66:41:E0:24:A8 -i hci0 -I [BC:66:41:E0:24:A8][LE]> connect Attempting to connect to BC:66:41:E0:24:A8 Error: connect error: Transport endpoint is not connected (134) [BC:66:41:E0:24:A8][LE]>6th March 2017 at 1:48 pm #63700
Could you perhaps share which Debian version you are running and which image is flashed on the Ci20?
The Bluetooth hardware is a bit of a black box basically. The kernel loads the firmware for the chip. And then the interface to the bluetooth chip from the JZ4780 and kernel perspective is a simple UART tx/rx wire. I’m not aware of any kernel configuration options required for Bluetooth audio.
The rest of the Bluetooth stack is in userspace as far as I know. You could check your BlueZ version perhaps. If you are using pulse-audio, perhaps you would need to install pulseaudio-module-bluetooth ?
