[QUOTE="mm1352000, post: 1182225, member: 82144"] [USER=141969]@CyberSimian[/USER] Perhaps we should open a new thread for these posts... Theoretically the problem could be in one of two places: [LIST=1] [*]The receiver's command processing. [*]The remote control's command generation (specifically: toggle bit handling). [/LIST] How is it that you're so sure that the receiver is at fault? Personally I can't think of any way to categorically prove that the problem source is one or other without checking what commands the remote is producing [at the protocol/bit level]. Unfortunately for me I don't have the appropriate hardware so I can't test. It's a very clever piece of logic... :notworthy: ...but it makes at least two implicit assumptions that ought to be clearly stated and/or explained: [LIST=1] [*]Which commands does each receiver receive? [*]How is the remote manipulating the toggle bits? [/LIST] Certain combinations of these two variables can lead to contradictory conclusions about the source of the problem. ;) If you still have the ability to reproduce this problem, I'd be interested to see IRSS debug-level log files corresponding with the test case. This would enable us to confirm or reject the hypothesis you outlined in your GB post. P.S. I assume you're aware that RC-6 has a standard toggle bit which [apparently] is fixed-value for Microsoft RC-6 commands, and that Microsoft RC-6 commands have a separate non-standard toggle bit. This adds to the complication and expands the set of possible explanations for the problem. [/QUOTE]
