![]() The sniffer is turnkey and painless: if you have an Ubertooth you can begin sniffing packets right now by running a single command. I also discovered weaknesses in BLE's security and wrote a tool to decrypt packets under some circumstances. My sniffer is highly robust and can capture data from connections on data channels. I've been researching BLE (also known as Bluetooth Low Energy and Bluetooth Smart) since 2012, and I wanted to share the BLE sniffer I built on the Ubertooth platform. Another interesting approach is to use a narrowband radio as a sniffer, like the one on the Ubertooth. His work is very interesting and is a good way to get starting playing with BLE on the cheap.Ī software defined radio approach is very powerful, and if you're interested in sniffing Bluetooth with SDR you should definitely check out gr-bluetooth. ![]() ![]() Recently Omri Iluz wrote about his experiences capturing BLE very cheaply using an RTL-SDR and an MMDS downconverter.
