From 63838725c6478102894cfb88feb2a9b1c331855d Mon Sep 17 00:00:00 2001 From: Mat Martineau Date: Thu, 17 May 2012 20:53:45 -0700 Subject: [PATCH] Bluetooth: Reassemble all available data when retransmissions succeed. As retransmitted packets arrive, attempt to reassemble SDUs. If all requested retransmissions have been received, acknowledge them and transition back to the RECV state.
