Cannot decrypt and filter the BT mesh packets with Wireshark

Hello All,

I am newbie and trying to sniff BT mesh logs using wireshark with nrf52840 dongle. I was successfully able to sniffer the wireshark packets for BT mesh. But currently I am facing two issues. After adding net key(0x34CBB351D5891900A00FB8B3D247D694), app key(0xAB3C4F1E983C9BEE4D7733827763EC7B), device key(0x975460D781FA59E0A97898A60BAF0062) and source address, but I am unable to get the info in the packets (decryption) which I need for debugging.

Also I am not able to filter only "BT Mesh" packets in the wireshark as of now. It would be of great help if there is any way to do that.

Hi again,

You might want to ask Wireshark about this.

There is a ble mesh extension to wireshark in which you can add the network and device keys, but I believe there is still as issue decrypting the application layer. For more info see this previous case.
