Description

I am using this library https://github.com/lemmingDev/ESP32-BLE-Gamepad on ESP32 Dev kit and all is working fine due to the smaller form factor I bought the ESP32C3 board that is advertised BLE and Wi-Fi again.

My sketch from the above library compile but the HID Device is never visible and able to connect on esp32c3 as its possible to ESP32 Dev Kit is there any issue I have to wait to be resolved or some hackery to enable the bluetooth to work as in the other module ?

Sketch

/*
 * This example turns the ESP32 into a Bluetooth LE gamepad that presses buttons and moves axis
 *
 * At the moment we are using the default settings, but they can be canged using a BleGamepadConfig instance as parameter for the begin function.
 *
 * Possible buttons are:
 * BUTTON_1 through to BUTTON_16
 * (16 buttons by default. Library can be configured to use up to 128)
 *
 * Possible DPAD/HAT switch position values are:
 * DPAD_CENTERED, DPAD_UP, DPAD_UP_RIGHT, DPAD_RIGHT, DPAD_DOWN_RIGHT, DPAD_DOWN, DPAD_DOWN_LEFT, DPAD_LEFT, DPAD_UP_LEFT
 * (or HAT_CENTERED, HAT_UP etc)
 *
 * bleGamepad.setAxes sets all axes at once. There are a few:
 * (x axis, y axis, z axis, rx axis, ry axis, rz axis, slider 1, slider 2)
 *
 * Library can also be configured to support up to 5 simulation controls
 * (rudder, throttle, accelerator, brake, steering), but they are not enabled by default.
 *
 * Library can also be configured to support different function buttons
 * (start, select, menu, home, back, volume increase, volume decrease, volume mute)
 * start and select are enabled by default

You really will need to ask the developer of that library. NimBLE absolutely works on esp32c3. Turn on verbose debugging and see if you are getting an error during runtime that would indicate why the service is not advertising properly.

@lbernstone thanks for the feedback I assume you are telling me to enable NimBLE logging I couldn't find any info on how to do that is there any document ?
