asked in ESPaper by (150 points)

How can I change the configured WiFi password on the ESPaper? I've flashed the espaper-client firmware which went well, but after entering the WiFi password it can't connect to the WiFi. Looking at the console output reveals that the password has been shortened and only the first 20 characters have been saved:

By getting into configuration mode: press and hold the left button, then press and release the right (reset) button, then release the left button. Now you should be back in configuration mode where you can set your WiFi credentials.

If that doesn't help: there is a line SPIFFS.format() in the main class. Uncomment it so that the file system will be formatted. Then you should get into configuration mode automatically...
