Hey @idomenashko,
Can you specify the fingerprint sensor used? [R50x/FPM10A]

Hey I have the same issue
I used R503

Hey @antonbek89
So the R503 has a different function to match scanned fingerprints.
It was raised at #10 and a PR was made at #20, do take a look at past issues/PRs while raising a new one (#24).

https://github.com/EverythingSmartHome/fingerprint-mqtt/blob/master/fingerprint-mqtt/fingerprint-R503-mqtt-led-WDT.ino
The code was adapted for R503 and an ESP32; with LED states defined for different errors, reading, learning and scanning mode.

If you need to use it with a compatible esp8266 like a wemos d1 mini, do make the necessary modifications for the wifi and other libraries. There's even a restart trigger (watchdog) if it loses connection to the wifi network, this is because a reconnection strategy is not implemented in the original code.

I have the same issue (a Communication error) with the As608 Fingerprint Sensor. Any quick way to fix this?

on a related note: the mqtt topic is empty when running the standart iso file:

or maybe it has something to do with this?
