Once you start nRF Sniffer for Bluetooth® LE, the plugin reports advertisements and lists nearby devices in the Device List. The software interface has several commands for controlling the operating mode of the nRF Sniffer.
Note
The nRF Sniffer might not pick up all connect requests and does not always pick up on a connection. In such cases, reconnect and try sniffing again. If you do not see any activity in your Wireshark console, see Troubleshooting.
The nRF Sniffer has two modes of operation:
- Listen on all advertising channels to pick up as many packets as possible from as many devices as possible. This is the default mode.
-
Follow one particular device and try to catch all packets sent to or from this particular device. This mode catches all:
- Advertisements and Scan Responses sent from the device
- Scan Requests and Connect Requests sent to the device
- Packets in the connection sent between the two devices in the connection
