Hi,

The official supported hardware is covered in Chapter 1.1 in the nRF Sniffer User Guide v1.4. To set up the Sniffer you will need one of the following kits :

• nRF51822 Evaluation Kit (PCA10001) and a mini USB cable
• nRF51422 Evaluation Kit (PCA10003) v3.0.0 or later and a mini USB cable
• nRF51822 Development Kit dongle (PCA10000)
• nRF51-DK (PCA10028) v1.0.0 or later and a micro USB cable
• nRF51 Dongle (PCA10031)

According to RedBearLab they also support the nRF-Sniffer: redbearlab.com/.../, so if you get "Sniffer ready and connected on COM15" it should be working. Make sure that the BLE devices that you are trying to sniff are advertising. The devices that are advertising should be listed under "Available devices".
