Issues with EM4425 : anyone tried that chip ?

theoroborus commented 6 months ago

Hello everyone.

I have EM chips under hand (ISO15693). I observe incoherence when reading multiple units when they all should be the same chip.

Does anyone has experience with this EM chip ?

Have you run this firmware on your device when testing?
