There is bluetooth issue while pairing with remote device ,When we try to pair our device then it take almost 30 to 35 seconds to pair ( And during this period device gets connected also),after this interval device remains unpair and unconnected.
Following are the logs we get:
[bluetooth]# pair 70:1C:E7:96:52:11
Attempting to pair with 70:1C:E7:96:52:11
