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. b.
