Can't get any NFC reading #165

mjvanderveen commented 2 years ago

I've made two separate setups of the ESP8266 and PN532 NFC. On one of them I left out the buzzer and light for now. Both are connected through ESPHOME into home assistant. This setup seems to work.

By both don't detect any NFC tags. I also can't find any log entries about the NFC tag scan. The switch #1 is up and the #2 is down on the NFC chip. The wiring I have: GND --> GND VCC --> 5V SDA --> D1 SCL --> D2

But i've tried other combinations of wiring.

What is the best way to debug this?

connect the ESP to you Computer and check the logs , hit the restart button on the esp8266 an check if it displays an error while trying to detect PN532 at boot ?

or just paste the logs here
