Bluefruit LE Sniffer with Wireshark fails to collect after c

by mdavison on Wed Jun 17, 2020 11:41 am

I am using a Bluefruit LE Sniffer FIRMWARE V2 (http://adafru.it/2269) to sniff BLE traffic between a device and a mobile phone. I am doing this through Wireshark V3.2.3 having installed the ExtCap from nrf_sniffer_for_bluetooth_le_3.0.0_129d2b3.zip. Everything seems to work OK in terms of seeing ADV packets. I then select the particular device I am interested in and packets are filtered down to that device. However, when the mobile connects to the device I see the CONNECT_REQ packet, then nothing until the mobile disconnects when advertising starts again.

I have tried this many times bearing in mind the comments in the FAQ at https://learn.adafruit.com/introducing- ... iffer/faqs (see the second question "When I connect..."), but the results are always the same, no packets after connect until disconnect. I can confirm that the device does indeed connect, notifies and the app then reads data because the app behaves as expected and shows that new data.

Any ideas how to see the data after connection?
