Moreover, reading and interpreting raw packet data gives you greater insight into how BLE works – something that would take much longer by only reading the theory, specifications, and even developing applications! Then you can blame your mobile developer or embedded developer for that pesky bug! (j/k! 😊 ) It integrates with Wireshark, an open-source, free software tool with many powerful features.īy becoming proficient at BLE sniffing techniques, you can troubleshoot bugs more efficiently and optimize performance by adjusting the settings of your Bluetooth Low Energy product accordingly.Īs a Bluetooth developer, this unique skill gives you “magical powers” to uncover the unknowns in many scenarios where things just aren’t working as expected with your Bluetooth Low Energy devices. It plugs directly into the USB port on your computer, so there is no need for cables. This combination is probably the most versatile and cost-efficient solution available today for sniffing BLE! Here are some unique advantages of this solution: One noteworthy BLE sniffer from that list is the Nordic Semiconductor nRF52840 USB Dongle (in combination with the nRF Sniffer and Wireshark). The list of Bluetooth LE sniffers varied from those costing under $50 to others costing tens of thousands of dollars $$$! If you haven’t read that article, I recommend reading it before continuing with this post.

In a previous article, we covered the basics of Bluetooth sniffers (aka Bluetooth protocol analyzer), how they work, and even a comparison of the different BLE sniffers available on the market.
