We now stock the ABSniffer 528. It’s a USB dongle that scans for Bluetooth devices and reports the data to a USB COM port.
The SBSniffer 528 can detect up to 100 Bluetooth devices per second.
Inside, there’s an nRF52832 that can be re-programmed using Nordic tools, SDKs and the J-Link interface.
The ABSniffer 502 scans for (any manufacturer) iBeacons and sends the data via USB/TTL plugged into a PC, Mac, Linux or Raspberry Pi. It shows up on the Raspberry Pi as /dev/ttyACM0. It communicates with PCs through a virtual UART port sending the MAC address, UUID, major, minor, measured power and RSSI. It can also be used to configure AprilBrother beacons via USB/TTL commands.
AprilBrother has a full list of AT commands.
