"Random" Fatal Error in ongoing operation
Posted: Fri Nov 25, 2022 6:17 amI have a sketch that reads a RFID Card with the MRC522 and send the results to an Webserver.
Everthing works fine, but after a random amount of time I get a fatal error and have to upload the sketch again.
Then it works again as espected, but the error returns sometimes.
The Error:
