Talk:Bye Bye Standby 2011 Protocol

I believe that the protocol actually has a 20-bit sender code followed by a 1-bit command ( 1 = ON, 0 = OFF). My evidence for this is limited to the single transmitter available to me at the moment, but if the command is five bits as stated here, then the command codes I see are 0x0A for OFF and 0x0B for ON, not as stated below. Since all four of the disputed bits are reversed on my controller, I conclude these are part of the sender code, not part of the command. For reference, my controller has a (20-bit) sender code 0xA4BC7 (interpreting the first bit in the stream as the most significant). There must be restrictions in this code otherwise some valid 2011 messages would also be valid simple protocol messages, but with the ON/OFF bit in a different position. Maybe it is simply that the first (most significant) bit is always 1, as this bit (and every second bit) in the simple protocol is 0? Any refutation or confirmation of these conclusions would be very welcome!

John,

My interpretation of the protocol was based solely on the remotes I have... if yours do not fit, then it must indeed be slightly wrong in the way you state.

It seemed a bit unlikely that all 3 of my remotes (purchased separately) should have matching bits in those positions if they weren't used for the command... but unlikely is not impossible!

I have a spreadsheet containing all of the codes used for my three remotes if you're interested... but it seems that we have further narrowed the control codes for the new protocol.

Thanks,

Nathan
