A small Arduino-ESP32 library that performs a true Bluetooth Classic (BR/EDR) inquiry scan via the Bluedroid GAP API — returning each discovered device's MAC address, name, RSSI and Class-of-Device (CoD). The BR/EDR analogue of a BLE advertising scan (MIT, last push 2020). Only finds devices in discoverable / inquiry-scan mode; pin it to a known ESP-IDF as it is unmaintained.
