Comment 11 for bug 1552410

14:15:05 here the car infotainment system is discovered during the device discovery process. The bluez correctly handles the device.

14:15:08 there is a pairing request that gets denied. The status 5 means Status Auth Failed. At the end the bonding is rescheduled for an another attempt.

14:15:12 the 2nd pairing attempt is made. Consequently this attempts fails too however this time with Status Rejected code. (status 11 means Status Rejected`). It is important to note that this happens immediately w/o any waiting time in between (timeout).
