From 820ae1b865caa05e0614004d0183ca70de2b8665 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sat, 18 Nov 2006 22:15:00 +0100 Subject: [PATCH] [Bluetooth] Always include MTU in L2CAP config responses When sending a positive config response it shall include the actual MTU to be used on this channel. This differs from the Bluetooth 1.1 specification where it was enough to acknowledge the config request.
