Hi,

i am using nRF Sniffer to decrypt the BT Mesh packets with Wireshark, it can work smoothly. However, i tested and found that the packets device key encrypted cannot be decrypted and packets using netkey or appkey are all can be decrypted.

can you give me a hand?

many thanks.

What version of Wireshark are you running? I think 3.4 has some improved decryption support.

Hi Bro,
