Bluefruit LE Sniffer - Bluetooth Low Energy (BLE 4.0) - nRF51822 (Firmware Version 2) Ecosystem_Qwiic/STEMMA QT You can also use theThe Bluefruit LE Sniffer is a USB Bluetooth Low Energy capture tool based on the Bluefruit LE Friend hardware. It passively listens to BLE traffic between devices and streams the data into Wireshark for packet level analysis. It supports BLE only, ships with Nordic Firmware V2, and requires a J Link for firmware reprogramming. Interested in learning how Bluetooth Low Energy works down to the packet level?
