Hi Bluez,
I found a pairing/connection bug in bluetoothctl.
* Steps to reproduce:
[bluetoothctl] scan on
[bluetoothctl] pair ble_device
[bluetoothctl] connect ble_device
[bluetoothctl] exit
Right after exiting from bluetoothctl, Disconnect happens like below.
< HCI Command: Disconnect (0x01|0x0006) plen 3 [hci0] 156.978499
Handle: 128
Reason: Remote User Terminated Connection (0x13)
> HCI Event: Command Status (0x0f) plen 4 [hci0] 156.995345
Disconnect (0x01|0x0006) ncmd 1
Status: Success (0x00)
> HCI Event: Disconnect Complete (0x05) plen 4 [hci0] 157.005387
Status: Success (0x00)
Handle: 128
Reason: Connection Terminated By Local Host (0x16)
@ Device Disconnected: 00:22:D0:8D:22:6D (1) reason 2
* My observation1:
This is not the case of the hcitool. It works.
* My observation2:
Right after receiving GATT services, bluez does some more work.
But the Value doesn't look like normal.
