Hi @shellpry2,
The USB that you have supports Bluetooth LE using the examples that we provide, You could use the device as a master or slave depending on your application.
But the device doesn't support the sniffer protocol because it is not enabled as a promiscuous mode for the Bluetooth LE protocol.
What is the issue that you are facing on? Are you trying to connect to a different device?
Regads,
Mario
