Good Morning Matan,
Thank you for your response, perhaps you could clarify somewhat?
I'm at a loss as to why only one-way audio is heard as my understanding is that it is also 'SCO' data right?
Looking at (the default) '/etc/bluetooth/audio.conf' I see the following which would imply that 'SCO' data is handled via 'HCI' (vs PCM?)
# SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
# Defaults to HCI
#SCORouting=PCM
That said, this morning I 'switched' it to PCM (as below) with no audio working at all! Using the very same config, I plugged in the USB dongle confirm that USB-bluetooth audio still works.
# SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
# Defaults to HCI
SCORouting=PCM
Also, in the forum link I provided at the end of my first post, someone mentioned some 'custom hci commands' might need to be written to the TiWi-R2 device. Might you know of some documentation on these commands? Is there a way to 'reset' the device to a known state?
