They lack the ability to sniff all transmissions that can occur on multiple channels simultaneously. Because the BLE traffic could occur on many different channels, basic analyzers may miss transmission. Using a lower-cost analyzer with Wireshark can be a great starting point for learning about BLE and uncovering initial bugs.ĭue to the complex configurations with BLE that arise from multichannel, central-peripheral, and client-server roles, a deeper analysis of the BLE transmission may be necessary to uncover the whole interaction. This can be useful for walking through scanning/advertising and the connecting process between two devices. At the base level, we can see specific devices are sending out packets with some product-meaningful data like Addressing Data.

The standard Wireshark view presents a lot of information and helps get users out of the dark when it comes to seeing wireless transmissions. Popular options like this include nRF Sniffer for BLE, Ubertooth One, and Adafruit’s Bluefruit LE Sniffer. More common and lower entry analyzers utilize development boards or less expensive hardware platforms to provide packet sniffing abilities. If LightBlue is not providing the level of detail and analysis that is required to troubleshoot, then knowing what other analyzer features exist will help prepare you for when you need to find out what your BLE packets actually look like. A common starting point for most may be inspecting troublesome devices with a BLE phone tool like our LightBlue app (a basic analyzer in addition to a BLE actor). Well, like most things in life, there are many different options to choose from, with a varying range of capabilities across different analyzers. So the next time you run into a problem while developing with BLE, you just need to get an analyzer, right? We have example code using the python API that will work on any OS to log the sniffed data to a pcap file for analysis so you can use this sniffer with any OS with python.Common points of failure in BLE communication: incorrectly defined advertising flagsĪppropriate central/peripheral designationį ailure to pair, bond, connect, or disconnect

The Nordic Wireshark-streaming sniffer software is currently Windows only. You can only use this device to listen on Bluetooth Low Energy devices! It will not work on Bluetooth (classic) devices. The sniffer firmware cannot be used with the the Nordic DFU bootloader firmware, which means that if you want to reprogram this devices you must use a J-Link + SWD adapter! You cannot over-the-air reprogram it. Plug it into your development machine, fire up the special sniffer bridge SW, select the device you want to sniff, and it will fire up Wireshark for you and start pushing data in via a live stream (using Nordic's Windows software), or save to a pcap file that you can analyze with Wireshark later.

You can passively capture data exchanges between two BLE devices, pushing the data into Wireshark, the open source network analysis tool, where you can visualize things on a packet level, with useful descriptors to help you make sense of the values without having to crack open the 2000 page Bluetooth 4.0 Core Specification every time.

This Bluefruit LE Friend is programmed with a special firmware image that turns it into an easy to use Bluetooth Low Energy sniffer.
