Want to know what kind of BLE devices are in your vicinity? The Cluetooth Scanner listens for advertising packets from nearby devices and displays info about them. Info can include:
- Name – the device’s advertised local name if present
- RSSI (signal strength) – received signal strength in dBm
- Address – the device’s MAC address, either public (permanent, manufacturer-assigned) or random (device-generated, may rotate for privacy)
- Company – decoded from the Manufacturer Specific Data (MSD) company ID bytes
- Chip – the silicon vendor inferred from the OUI (first 3 bytes of a public MAC address), e.g. Espressif for ESP32-based devices
- Services – advertised GATT service UUIDs decoded to profile names where known
- Appearance – standardized Bluetooth SIG device category code
- Apple Type – apple Continuity message subtype
- Guess – a best-guess device type for Apple devices based on advertisement payload analysis
- Scan count – how many times the device has been detected across scan cycles
