I have an xM1 implant that i want to unlock block 0 to change the uid. I want to do this with an arduino and either the pn532 or the rc522.
I read that the pn532 is reliable with the x series implants, but is there a library to unlock block 0 like the one from miguelbalboa https://github.com/miguelbalboa/rfid/ ?
The rc522’s field is pretty weak and does often not read the implant. if anybody has experience in building antennas this would also help.
I am pretty new to arduino and nfc but i have some experience in programming.
Edit: maybe it’s important to know what i want to make: i want to make a portable uid cloner that i can connect via BLE to my phone and send commands. It’s a project for the end of my apprenticeship
