The Bluefruit LE Friend is a Bluetooth Low Energy (BLE) sniffer that allows you to capture and analyze BLE data exchanges using Wireshark. Ideal for debugging BLE hardware or developing custom apps, it provides packet-level insights into BLE communication. The device works with BLE devices only (not classic Bluetooth). It features Firmware V2 for improved streaming compatibility across all operating systems. Please note: reprogramming requires a J-Link programmer and SWD adapter, as over-the-air reprogramming is not supported.
Revision History:
-
As of June 17, 2022 - This board may come with a different regulator than AP2112K due to parts shortages. The regulator can provide at least 150mA.
-
As of March 23, 2022, We've updated the board to use CP2102N instead of CP2104 as the CP2014 has been discontinued and replaced with CP2102n. This USB-to-Serial chip is the same functionality and driver.
-
As of August 2018, We now ship the sniffers with Firmware V2 - this improved firmware from Nordic now has better Wireshark-streaming sniffer software that works with all OSes for live-streamed BLE sniffing
-
As of April 5, 2017, the board has been updated to change the USB-Serial converter chip to CP2104 and remove the SWD connector (you can get to the SWD connection pads on the bottom of
-
As of July 31st, 2015, we're selling an updated version with a black PCB -
the firmware/sniffer code/usage is identical, just the PCB color has
changed!
