No Tag scnned ESP32 with PN532 testes oder SPI and I2C

Gompman · October 20, 2021, 11:20am

Hey folks,

first topic

I am currently having problems with the PN532 and an ESP32.
The project is based on the standalone tag reader from adonno.
However, I need more IO inputs for buttons. Hence the ESP32.
Buttons work like charm.

Using I2C, I can sometimes read RFID tags after flashing. but only a few times. As a test, I have now connected the RFID reader via SPI. here is an attached LOG:

I have the same issue, did you manage to find a solution? Other people who had this problem said it was a wiring issue, but I checked and it doesn’t seem to be the case

Gompman · November 1, 2021, 8:50pm

I tested with another esp32 board and another rfid board. Same result. I switched back to esp8266 d1 mini. Works like a charm.

00punisher · September 20, 2022, 9:08pm

I have the same issue, any solution? Thanks!

ibarbech · January 19, 2023, 11:37am

I have the same problem with pn532_i2c, pn532_spi never worked for me.
I found a solution for pn532_i2c, but it doesn’t work for pn532_spi.
The solution is add 4.7k pullup resistor to 3.3v for sda and scl.
I want to read 2 pn532, one for entry and one for exit.
So I need to use pn532_spi and pn532_i2c.
If someone can help me, I will be very grateful.
Good luck with your project.
