ESP-12f to Fingerprint via Softserial
Posted: Thu Apr 22, 2021 2:06 pmHi,
I know softserial is unstable. Anyhow, I'm trying to connect my esp12f since many hours to connect to an fingerprint. I enrolled the fingerprints via an pro mini, did set an passwort, everything fine.
But connecting to the esp-12f doesn't work. It simply goes into the OTA Update. Here is my sketch:
Any help is appreciated.
