Compiles fine for me in Arduino 1.8.19 and also the Arduino web editor

Compiles fine for me in Arduino 1.8.19 and also the Arduino web editor
I got my code to compile uninstalled the IDE, deleted all the leftover folders did a new install
now my issue is it compiles it connects once but will not reconnect if you remove power.
what am I doing wrong??

Please post your code between triple backtags ` so it shows correctly...

Your code compiles and I can pair it, but doesn't show up as a controller for me

I tried removing all of the custom vid/pid/serial etc stuff and it's working

Also, you set bleGamepadConfig.setAutoReport(true);, but then you manually call bleGamepad.sendReport();
I set auto report to false below
I changed the delay to 20ms, which polls approx 50 times per sec

Try the code below and see if it works
REMEMBER TO UNPAIR/REMOVE CONTROLLER FIRST

        bleGamepad.press(buttonNum);
        bleGamepad.sendReport();
        delay(100);
        bleGamepad.release(buttonNum);
        bleGamepad.sendReport();
        delay(25);
    }

    // Check if any potentiometers are rotated
    int potValueRY = analogRead(potRY);
    int potValueRX = analogRead(potRX);

    bleGamepad.setRY(potValueRY);

    bleGamepad.setRZ(potValueRZ);

    bleGamepad.sendReport();

    delay(1000); // Add a delay before trying to reconnect

Also, your analogs won't move much as analog read will return a value from 0 to 4095, though you've set the setAxesMax to 0x7FFF which is 32767

You should change:

bleGamepadConfig.setAxesMax(0x7FFF); // Axes maximum value

to

bleGamepadConfig.setAxesMax(0x0FFF); // Axes maximum value

[lemmingDev]

So, I'll close this soon if I don't hear back
