The STM32 sniffer for Bluetooth® Low Energy allows you to learn, analyze, and debug Bluetooth® Low Energy communications.
You will be able to listen to advertising packets or follow communications between two devices. If the devices are paired, it may even be possible to decrypt the packets.
There are two STM32 sniffer solutions targeting the following devices:
- STM32WB55
- STM32WB09

1. Installing the STM32 sniffer
The STM32 sniffer for Bluetooth® Low Energy consists of two main parts:
- The software part, running on the computer, which captures, analyzes, and displays packets.
- The firmware part, running on the STM32WB MCU, which intercepts over-the-air packets.
