Forwarder encapsulation

Hi.

I need to use MQTT-SN implementation over Digimesh network. I'm thinking on use and build digimesh forwarder to emqx udp port. At MQTT-SN specs, point 5.5, i have read there is special encapsulation for forwarder packets.

Is this encapsulation spec supported by this plugin? I was reading plugin information but I didn't find anything related.

Thanks in advance. Best regards.
