[Feature Request] Add ESP32-BLE-Gamepad support

[LeeNX]

More like a Feature Confirmed, mostly.

I was able to connect to bluepad32 running on an ESP32-Dev board, with an ESP32-C3 running TestAll.ino sketch from ESP32-BLE-Gamepad

bluepad32 reported the following on re-connect

Controller model: Android, VID=0x02e5, PID=0xcdab
idx=0, dpad: 0x00, buttons: 0x0000, axis L: -512, -512, axis R: -512, -512, brake:    0, throttle:    0, misc: 0x02, gyro x:     0 y:     0 z:     0, accel x:     0 y:     0 z:     0
idx=0, dpad: 0x00, buttons: 0x0000, axis L: -512, -512, axis R: -512, -512, brake:    0, throttle:    0, misc: 0x04, gyro x:     0 y:     0 z:     0, accel x:     0 y:     0 z:     0

I can confirm changes in the attrib as per the TestAll sketch. I was thinking it might be possible to add the battery status in the serial reporting.

Might be worth adding a note to the Android section about making your own gamepad that would be supported.

I don't have any other ESP32 device, so I can't test a pure BLE setup, but that is something I plan too do.

Thanks for testing it.

regarding the doc, would you like to add the info yourself in the doc ? This file: https://github.com/ricardoquesada/bluepad32/blob/main/docs/supported_gamepads.md (use develop branch).

Reporting the battery, yes, that is pending for BLE devices.

I can try over the weekend. See if I can make something that is acceptable.

Thanks

Thanks @ricardoquesada , I was not sure if more info or details to the TestAll.ino sketch was worth putting into the docs, but I think we can close this as it's merged.

If you think anything else is worth adding, let me know.

Thanks. I simplified the doc a bit.
