I found this log when execute av connect command:
< HCI Command: Disconnect (0x01|0x0006) plen 3 [hci0] 215.582054
Handle: 71
Reason: Remote User Terminated Connection (0x13)
I doubt that why "Remote User Terminated Connection", because when I
heard "connected" from Bluetooth headset and I have done nothing with
it. The full log when execute av connect command is attached. Thanks.
