Let me know if there is a particular LFRFID protocol you want me to do a video on. Otherwise, I'll just create my own random protocol using a variety of features (like Manchester, FSK, PSK, etc.)
Thank you for the very informative video! For the past few weeks I have been trying to read/decode an 125kHZ RFID Key, which uses an unknown protocol. The flipper can only read the raw data, which i visualized in a python program but I am struggling to get information out of it. Do you have any idea how i could decode it? Thank you in advance! :)
Which Python program are you using? Do you have a screenshot of part of the signal that you can share on my Discord? discord.com/invite/NsjCvqwPAd (or share directly with me at @CodeAllNight on Discord.) The next few videos are going to be looking at different modulations for 125kHz RFID. The first step is to try to figure out which modulation you are using (Raw, FSK, PSK, Manchester, etc.) Next, you have to work to convert the data into bits (the data itself can also have different encodings, such as Manchester). Often the protocols have some embedded checksum data, so every so many bits, there may be an extra bit or two with parity information. The idea of how to encode a 0 or 1 isn't universal (so try inverting your data; 1->0, 0->1). The order of bits can be most-significant bit or least-significant bit. If the data is larger than 8 bits, the bytes can also be ordered in MSB or LSB order. Try to see how often the signal repeats, your captured data might not be perfect (so you will want to analyze multiple copies).
Amazing every smart thanks for teaching us all 💯💯👍
So nice of you. Hopefully next week we can make our own encoder/decoder!

Great Video. This is slightly more in depth than Im familiar with. But enjoy learning this stuff.

@@MrDerekJamison I posted on your Discord in your nfc-rfid channel.
@@stonecrop1874 Awesome, thanks! Hopefully someone replies, otherwise I'll try to look at it this weekend.
