Strange errors with RFID1356MIFARE in USB-CDC mode

[GeorgeFlorian]

I've plugged the RFID1356MIFARE in USB-CDC mode to the PC.
I've opened a terminal using picocom -b 115200 /dev/ttyACM0 and then this happens:



I did not write those AT commands. That happens all on its own.
And it happens almost every time I plug the board in and open the picocom terminal.

What is up with that ?

Thank you.

I would like an explanation as to why do I have to do that.
Thank you.

It's part of Linux that otherwise interferes as you have found.
