Battery Request Second time disconnection

[magesh vasudevan]

Issue: when the battery level is requested for the first time from mobile its responding correctly. but, when it is requested for the second time from mobile, disconnection happens with message unknown error (0x3b).

[Sigurd]

The error 0x3b is caused by "Unacceptable Connection Interval". What values are you using for these parameters ? MIN_CONN_INTERVAL, MAX_CONN_INTERVAL, SLAVE_LATENCY and CONN_SUP_TIMEOUT ? It may be that the bluetooth stack used in motoE does not accept the connection interval parameters you are using.
