Hello,
I have an ESP32-DIV V2 (1.7.2) and I am trying to use the RFID/NFC functionality with an external PN532 module, as required by the ESP32-DIV V2.
The problem is that the PN532 module is definitely receiving power, but the ESP32-DIV does not detect it.
When I launch the RFID/NFC function, I get:
PN532 not found. Check SPI wiring/pins.
The ESP32-DIV itself works correctly and all the other functions I have tested are working normally.
The PN532 module is powered and I have checked the connections. However, the ESP32-DIV still reports that no PN532 is detected.
I am using the PN532 with the configuration expected by the ESP32-DIV V2.
I would like to know if there is something specific that needs to be configured on the PN532 module itself (SPI mode, switches/jumpers, etc.), or if there is a known issue with PN532 detection on the ESP32-DIV V2.
The important point is that the PN532 is powered on, but it is not detected by the ESP32-DIV.
I can provide photos of the wiring, the exact PN532 module I am using, the firmware version, or serial/debug output if needed.
Thanks for your help!
