nRF sniffer doesn't capture any packages after the connection is established

I try to capture a BLE connection with the nRF Sniffer.

I can see the advertisement packages, but after i established a connection from an andriod device i didn't get any packages.

What i did:

1.I start scanning for BLE devices with nRF Sniffer

2.Select the device i want to watch

3.start Wireshark.

At first when Wireshark starts up it shows me the advertising packets (should it do that if i select a specific device ?, it also shows other advertising BTE devices).

4.Then i did start the BLE connection from my mobile device.

Wireshark didn't show any connection related packets The only thing i can see are advertisement packets from other BLE devices without connection.

Is there any known issue ?

  • It is recommended to use Wireshark v1.10 with the nRF Sniffer. It is the latest version that have been tested. Your procedure is correct, but what could happen is that the sniffer is unable to sniff the connection request, then it will not be able to follow the connection. You should have the sniffer close to both devices. Also, try to turn off other Bluetooth devices that you are not testing with, and disable Bluetooth on central devices that sends out scan requests(smart phones etc.) Also, you should try to replug the dongle.
