When a user initiates pairing with a BLE Bluetooth mouse,
MGMT_STATUS_CONNECT_FAILED(0x04) is returned with a low
probability, resulting in pairing failure. To improve
user experience, retry bonding is performed when
MGMT_STATUS_CONNECT_FAILED is returned.

Just retry once when MGMT_STATUS_CONNECT_FAILED occurs
because this status may be continuously returned.

Debug log:

Great, I think you are right if kernel does not continue to return MGMT_STATUS_CONNECT_FAILED status.

My idea is to retry only once after returning MGMT_STATUS_CONNECT_FAILED,
it can avoid repeated retry when continuing to return MGMT_STATUS_CONNECT_FAILED.

Cheers,
Chengyi

Hi guys,

I would like to ask if the patch I submitted is valuable. 
Maybe its effect is weak, but do you agree to merge it? Thanks.
