Hello

Hello from Germany

I have two Proxmark devices: one to send data and one to sniff and capture the data sent by the first device. I'm sending a 4-byte sequence, specifically '3FFE1FB6' using the function 'em4x70_send_bit' from em4x70.c soruce file , and using the lf sniff command on the second Proxmark to capture the signal.

I've uploaded a file containing the captured data for reference.

My problem is that I'm unable to demodulate the captured data to extract the original bytes ('3FFE1FB6') sent by the first Proxmark. Can someone help me with this issue?

Thank you.
