**
** This problem was observed first hand on a BMW 2005/E46 car kit which does
** not send AT+BRSF and behaves as if it would not support 3WAY. With the newly
** introduced code for using attr_value as peer_feature the result was that
** bluetooth connections to the car kit always terminated after 5 seconds
** (via BTA_AG_SVC_TOUT_EVT).
