@Marco
On my machine with BT moudle 8087:0026, I reproduced the problem, and
replaced with 20.10 firmware ibt-19-0-4.sfi, but still could not work in
hsp/hfp mode.
What I found is the bt driver can't receive the SCO packet, the returned
packet length is always 0.
And if the bt headset can't work in the hsp/hfp mode, please run hci config, if
the output like below (RX bytes: sco:0 TX bytes: sco:1), that means the bt
driver can't receive SCO packets, as a result the headset can't work in hsp/hfp
mode since hsp/hfp mode depends on SCO link.
