Hello guys this is a submission for my apartment garage opener.
Here are high res pics of the back of the fob as well as the PCB. The sticker on the back of the fob is faded but when I searched for it this is the info for it.
IC: 6540A-RANGER
make normal long entries. and several button presses for 3+ seconds while holding each of the buttons
I was able to get it working. Thank you all for your help.
your protocol is rolling, Manchester transfer is 3500 bit/sec. transmits the same code when the button is held down, and changes when the button is pressed again… how did you manage to make it work? or what do you mean
I emulated the sub for Button 1 that I attached and it works. No clue but started to work yesterday.
i.e. you just recorded Raw (how many button presses do you have in the recording?)
Yes I recorded raw and pressed the button 10 times like suggested when submitting subghz. When I replayed it the recording worked.
a prime example of a “resynchronization” attack
