Hi Daryl, > Will making the default value of credits zero break other things? I got some time to test this and it brings our RFCOMM code back to the behavior of 1.0b. The session wide credits value is useless and the dlc credits value must be zero in the initial place. But we must make sure that we request 1.1 credit based flow control for outgoing connections. The attached patch should solve all problems. Max, please review the patch to make sure I don't forget anything. Regards Marcel
