Cannot save configiguration

[videobuff]

Describe the bug The configuration is not saved to SPIFFS.

Environment Platformio Expressif 1.12.14 ArduinoJson@6.16.1

To Reproduce See the YouTube movie. I can do everything, but it wont save, and there is no proper id given, all are 0

Expected behavior Save it to SPIFFS to be able to recall later

Screenshots See the movie at youtube https://youtu.be/7pCqvhruycg

Also it does not work from the CLI. If i recall the config, it is always empty.

Thank you for the detailled description. Unfortunaltey the video quality is to low to recognize anything that is stated in the console/Serial output. Yet I can see different issues that seem to point to some incomplete UI in the SPIFFS. No Icons are showing for Steppers, Switches and Encoders also your output "listing files in root folder" is not complete. It shows only 5 files, yet in the current version of the UI it should be 10. Can you please post the output of your call to "Upload Filesystem Image" in platformio?

Here the output I get when uploading the current version of the UI:

Also I suggest to turn on debugging in your program at the point where you create the Stepper Motor instance. If you used something like this: stepperMotorServer = new ESPStepperMotorServer(ESPServerRestApiEnabled | ESPServerWebserverEnabled | ESPServerSerialEnabled, ESPServerLogLevel_INFO);

Then change it to this: stepperMotorServer = new ESPStepperMotorServer(ESPServerRestApiEnabled | ESPServerWebserverEnabled | ESPServerSerialEnabled, ESPServerLogLevel_DEBUG);

OR you can use the serial console of the ESP Stepper Motor server and just type (but then you would not get the debug output during boot): ll=4 to set the log level to all. Then try again in the UI to create a new config (just add a stepper with dummy data, no need to create a full fledged config before clicking save).

If this does not help in finding the cause, and you only need a fixed configuration, you can also create it manually in the "config.json" that you uploaded along with the UI.

A simple sample configuration would look like this:

{
    "serverConfiguration": {
        "port": 80,
        "apName": "ESP-StepperMotor-Server",
        "apPassword": "ServerPassword",
        "wififMode": 2,
        "wifiSsid": "",
        "wifiPassword": ""
    },
    "stepperConfigurations": [
        {
            "id": 0,
            "stepPin": 32,
            "directionPin": 33,
            "name": "X-Axis",
            "stepsPerRev": 200,
            "stepsPerMM": 100,
            "microsteppingDivisor": 1,
            "rpmLimit": 1000
        }
    ],
    "switchConfigurations": [
        {
            "id": 0,
            "ioPin": 14,
            "stepperIndex": 0,
            "switchType": 64,
            "name": "Limit 1 X-Axis",
            "switchPosition": -1
        }
    ],
    "rotaryEncoderConfigurations": [
    ]
}

just copy this into the config.json file and upload to see if reading the configuration works at all.

plase also post your main.cpp (without your wifi credentials ;-) if any)

The error was completely on my side. When I moved to my win10 PC, installed platformio and the project according to your instructions, all went well. Thanks very much. I have build an antenna rotor controller using a stepper motor in stead of the old fashioned 2 fase motor. using your library i should be able to control it in all aspects.
