 Differently than <u>**passive**</u> sniffers, which do not interact with the BT network (piconet), the **<u>active</u>** sniffer connects itself to the remote BT device (BR/EDR target) and allows testing the BT protocol down to the Baseband layer while guided by a BT host stack such as **[blue-kitchen](https://github.com/bluekitchen/btstack)**.
