What are HijelHID BLEKeyboard and BLEMouse libraries?

They're Arduino-compatible wrappers for NimBLE-Arduino, letting ESP32 act as BLE HID keyboards or mice across iOS, Android, Windows, macOS, Linux.

Do they work with ESP32 deep sleep for long battery life?

Yes—radio shuts off idle, integrates light/deep sleep, targeting months on coin cells.

How do I get started with these BLE HID libraries ?

Grab from GitHub (HijelHID_BLEKeyboard, HijelHID_BLEMouse), install via Arduino Library Manager, sketch examples included.
