No, if we are retransmitting a frame that means L2CAP didn't received an ack for it and we are already accounting it in unacked_frames and there is no need to increment unacked_frames in this case. > > Won't this cause the same frame to be accounted twice? > > If there are too many retransmissions, will there be a chance that > "unacked_frames" could cross 0xFF and over flow. No, unacked_frames number is limited by the remote transmission window size. -- Gustavo F.
