Based on BLEMouse2XAC BLEmouse2xac project – BLE Mouse/Trackball to Xbox Adaptive Controller Joystick

What it is

This project allows a BLE 5Bluetooth Low energy) mouse movement to be converted in keyboard arrow movements. An ESP32 (M5STack Atom S3) is connected to the BLE mouse via blueooth, and to a mobile phone (or a PC) via an USB link. The ESP 32 is seen as a keyboard that sue keycodes corresponding to the direction arrows.
