In my sketch using OTA I am defining a password:
I can update my sketch OTA via ArduinoIDE and it ask for the password. But I do not get prompted for password when uploading my LittleFS data via "Tools>ESP8266 LittleFS data upload".
I get this error:
Authenticating...FAIL 15:11:17 [ERROR]: Authentication Failed LittleFS Upload failed!
If I don't define an OTA password, I can upload both sketch and LittleFS data with no issues.
