Does the above still jive with all of this:
$ hciconfig hci0 lm
hci0: Type: BR/EDR Bus: USB
BD Address: 00:02:72:1E:E0:12 ACL MTU: 1021:7 SCO MTU: 64:1
Link mode: SLAVE ACCEPT
Notice the B/T adapter's link mode is set to slave, yet...
$ hcitool con
Connections:
> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER
In the connection with the mouse, the B/T adapter is master.
I can change it successfully:
brian@pc:~$ sudo hciconfig hci0 lm master,accept
brian@pc:~$ hciconfig hci0 lm
hci0: Type: BR/EDR Bus: USB
BD Address: 00:02:72:1E:E0:12 ACL MTU: 1021:7 SCO MTU: 64:1
Link mode: ACCEPT MASTER
Which doesn't change the connection with the mouse:
$ hcitool con
Connections:
> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER
When I connect the headset using the bluetooth-applet:
$ hcitool con
Connections:
< eSCO 00:18:6B:E5:4F:7E handle 6 state 1 lm SLAVE
< ACL 00:18:6B:E5:4F:7E handle 12 state 1 lm MASTER AUTH ENCRYPT
> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER
The connection with the headset itself has the B/T adapter as master but
this eSCO connection is slave?
Oh wait. The eSCO connection disappeared now:
$ hcitool con
Connections:
< ACL 00:18:6B:E5:4F:7E handle 12 state 1 lm MASTER AUTH ENCRYPT
> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER
Now that I play something through the headset it comes back:
Connections:
< eSCO 00:18:6B:E5:4F:7E handle 6 state 1 lm SLAVE
< ACL 00:18:6B:E5:4F:7E handle 12 state 1 lm MASTER AUTH ENCRYPT
> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER
I guess that eSCO connection is only active when there is audio sent to
the headset perhaps.
I sure wish I could get all of this to work reliably. Even if I had to
follow a recipe of manual steps -- something I have not yet been able to
figure out with any consistency.
