ESP32 firmware that scans for Apple AirTag / Find My MAC addresses and BLE payloads without an Android phone or nRF Connect (~110 stars, last push 2024-04). Passive scan only, no spoofing or emulation; output over UART. Supports ESP32-WROOM and ESP32-S3. Useful at the survey step to detect trackers in the environment.
Matches only the Apple Find My manufacturer-data patterns (1E FF 4C 00 and 4C 00 12 19), so it does not match the DULT service-data payload (UUID 0xFCB2) that second-generation AirTags are reported to send near their owner.
