Hi All, I traced code and found in some case headset is not unlocked well. for example when something goes wrong in headset_resume_complete(), client->dev = NULL so client_cb() will skip headset_unlock() then headset will be locked forever until restart bluetoothd. I have no idea what's the lock idea behind, BTW still unclear how the problem happens to cause this. Please help to provide idea. log: Nov 25 15:55:50 itrs-ubuntu bluetoothd[26202]: Accepted new client connection on unix socket (fd=22) Nov 25 15:55:50 itrs-ubuntu bluetoothd[26202]: Audio API: received BT_GETCAPABILITIES_REQ Nov 25 15:55:50 itrs-ubuntu bluetoothd[26202]: Audio API: sending BT_GETCAPABILITIES_RSP Nov 25 15:55:50 itrs-ubuntu bluetoothd[26202]: Audio API: received BT_SETCONFIGURATION_REQ Nov 25 15:55:50 itrs-ubuntu bluetoothd[26202]: config sco - device = 00:1E:DC:AB:6D:3F access_mode = 2 Nov 25 15:55:50 itrs-ubuntu bluetoothd[26202]: /org/bluez/hci0/dev_00_1E_DC_AB_6D_3F: Connecting to 00:1E:DC:AB:6D:3F channel 1 Nov 25 15:55:50 itrs-ubuntu bluetoothd[26202]: State changed /org/bluez/hci0/dev_00_1E_DC_AB_6D_3F: HEADSET_STATE_DISCONNECTED -> HEADSET_STATE_CONNECT_IN_PROGRESS Nov 25 15:56:09 itrs-ubuntu bluetoothd[26202]: /org/bluez/hci0/dev_00_1E_DC_AB_6D_3F: Connected to 00:1E:DC:AB:6D:3F Nov 25 15:56:09 itrs-ubuntu bluetoothd[26202]: telephony-dummy: device 0xb8486ba8 connected Nov 25 15:56:09 itrs-ubuntu bluetoothd[26202]: State changed /org/bluez/hci0/dev_00_1E_DC_AB_6D_3F: HEADSET_STATE_CONNECT_IN_PROGRESS -> HEADSET_STATE_CONNECTED Nov 25 15:56:09 itrs-ubuntu bluetoothd[26202]: State changed /org/bluez/hci0/dev_00_1E_DC_AB_6D_3F: HEADSET_STATE_CONNECTED -> HEADSET_STATE_PLAY_IN_PROGRESS Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: connect(): Connection refused (111) Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: headset_lock(before): hs->lock:0, lock:2, state:3 Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: headset_lock: pass lock check Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: headset_lock(after): hs->lock:2, lock:2, state:3 Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: Audio API: sending BT_SETCONFIGURATION_RSP Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: State changed /org/bluez/hci0/dev_00_1E_DC_AB_6D_3F: HEADSET_STATE_PLAY_IN_PROGRESS -> HEADSET_STATE_CONNECTED Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: Audio API: received BT_STREAMSTART_REQ Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: Audio API: sending BT_STREAMSTART_RSP Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: Audio API: sending BT_STREAMFD_IND Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: unix_sendmsg_fd: Bad file descriptor(9) Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: resume failed (headset_resume_complete) Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: Audio API: sending BT_STREAMSTART_RSP Nov 25 15:56:12 itrs-ubuntu bluetoothd[26202]: Unix client disconnected (fd=22), type:1, dev: Nov 25 15:56:17 itrs-ubuntu bluetoothd[26202]: Received AT+CLIP=1 Nov 25 15:56:17 itrs-ubuntu bluetoothd[26202]: Received AT+CSCS="UTF-8" Nov 25 15:56:17 itrs-ubuntu bluetoothd[26202]: Badly formated or unrecognized command: AT+CSCS="UTF-8" Nov 25 15:56:17 itrs-ubuntu bluetoothd[26202]: Received AT*SEAM="HBH-PV720",13 Nov 25 15:56:17 itrs-ubuntu bluetoothd[26202]: Badly formated or unrecognized command: AT*SEAM="HBH-PV720",13 Nov 25 15:56:17 itrs-ubuntu bluetoothd[26202]: Received AT+CLAN?
