ESP32C3 Connects to Generic AB Shutter Clicker
/**
*
* This code is a BLE client for the AB Shutter3.
* It scans for the AB Shutter3 and connects to it.
* It then subscribes to the Input Report characteristic and waits for button events.
* When a button event is received, it prints the button event to the serial monitor.
*
* The code is written in C++ and uses the NimBLE library.
*
* The code is written for the ESP32 board.
