WIP NOTE - this outlines the process of decoding. if you just want the protocol, go to protocol

FIRST STEPS

i knew that the collar was 433MHZ - and since I have access to an SDR, I grabbed it and took a look at the transmissions coming from the collar remote.

Initially I tried to convert them automatically using logic analyser software - this was a HUGE waste of time so I ended up just making a document and converting them manually

you can see my document here

once they were all decoded into binary, it became pretty clear what the protocol did as I captured more examples.

***NOTE - the section in the middle is your "Secret Key" - you need to find this out if you want to use your remote AND your PC at the same time. if you don't care and just want to use your PC, just choose a random key.
