At least I know how to generate IDs that do have 0x23 as base frequency... I could implement it like that and that should be fine, but I'd prefer to crack it thoroughly, nice brain teaser

I have uploaded the capture of another transmitter in a new folder. Hope it helps, thank you.

Thanks, even if I don't understand the mapping thoroughly yet (that may require up to 32 extra Rx captures ...) I think I should be able to make a test build during the week-end and there should be enough entropy to be able to fly with several deviated transmitters in the same area without interferences.

I can make further capture if necessary. I can also ship you the FC board if it is easier for you. By the way I have received the Q303 board, thanks.

Here is a test build, please test with several transmitter IDs:

diff

It's not thoroughly cracked, but if it works that should be fine for now ...

Performance of the new build is good. I have spent 30 minutes playing with ID's made up of 1 to 6 digits and all can bind. Great job !

Cool !
That is good enough for now... now to the CX10D
