Is it possible to sniff 6lowpan\coap over BLE with wireshark?

[Phil Beeson]

I'm using the latest SDK (14.1) and have got a working COAP server running over BLE on a nRF52DK, and can exercise the service from my Ubuntu desktop without any problem.

I have a separate windows machine running the Nordic sniffer which I've been using successfully to sniff GATT data.

Is is possible to configure Wireshark to decode the 6lowpan traffic over BLE, if so how.

At the moment I can see the connect request, but no more. I'm not sure if I'm just missing a configuration step, or if there's some fundamental piece not missing. I can't believe I'm the first person to try this, but I don't see anyone else asking the same question.

Any suggestions?

Thanks.

From the provided capture file it looks like the Sniffer is unable to follow into connection to capture the packets.

Wireshark will show this without any configuration, except from the key files if you are using DTLS. This screenshot shows how it will look like in the packet details:

There is a known issue with the nRF Sniffer where it is not able to follow link into a connection, please see this answer for some suggested solutions.
