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.
Espressif ships Bluetooth Classic discovery in arduino-esp32 with a maintained example (bt_classic_device_discovery, added 2021-04). This library's last commit is 2020-12-27 and issue 1, an undefined reference to BTAdvertisedDevice::getServiceUUID(), has been open since 2019-08-11. Source · checked 2026-09-28
