Describe the bug:
I'm trying to interface the RC522 RFID reader to my M5 Stick C Plus 2, but it's not found. I already checked cables and they are correct according to the pinout. I also setM5 RFID2 in the config menu.

Steps To Reproduce:

  • Device used:
  • M5Stick CPlus 2
  • RC522

Expected behavior:
I can read tags with my board

Actual behavior:
When clicking on Read Tag, i get the error "RFID module not found!"

Additional context / logs:

Selected: Read tag
[ 71701][W][Wire.cpp:301] begin(): Bus already started in Master Mode.
unsupported serial command: _
failed: _
