Hi.

Sniffer for the BLE Mesh is now available till the Network layer. (Advertising bearer)

This should provide some debug capability, but we are still missing application layer decryption support.

______________________________

Please use Wireshark version 2.6.2 or later for sniffing BTLE Mesh messages.

Dissector to use use -> btmesh

Set the Network keys and IVIndex in -> Preferences -> protocol -> Bluetooth -> BT Mesh

***Unfortunately this will only decrypt using the network key, as decryption of the application key is not yet available.

Best regards,
Joakim.
