Can't read NFC-Tags #226

Hi, Everything is connected right (I tested every connection with a multimeter). The switch 1 on the reader module is on (up) and switch 2 off: 20230220_232237 20230220_232132 20230220_232159 20230220_232225

The ESP is shown in HomeAssistant as a device of the service ESPHome. So the ESP is recognized. I once connected a LED to it and I could control it with the TagReaderLED switch within Home Assistant, so HomeAssistant can communicate with the ESP. But when I put a NFC-Card on the reader, there is no event in the logbook. The NFC-Card works fine with my smartphone (it's the one the Reader came with).

I was running a very old version of this project and mine was working until today when I updated it because I didn't have the LED and Buzzer enabled.

For me, the esphome appears in hass but like you, the NFC reader no longer works. I'm not sure what specifically the issue is yet. I'm still trying to work it out.

For me it turned out to be bad soldering. Even though I checked every connection with a multimeter, resoldering the NFC-Reader to the cables did the job for me.

After some closer looking, mine is wired completely different. It looks like a lot has changed since I built mine. So I guess I find old firmware or re-wire it.

@BjGoCraft when you re-soldered did you have to remove the jumper pins and directly solder the wires? How did you resolder?

no, I didn't remove the jumper pins. It still looks like on the pictures. I heated up the solder and pumped it away with a desoldering pump. Then I just soldered it again, but this time the soldering points were cleaner so everything has a stable connection
