Hello there!

I m looking for the protocol used over websocket by mender connect addon to perform terminal session, file transfert and port forwarding.

Is it available somewhere ?

The source code is available at [GitHub - mendersoftware/mender-connect](https://github.com/mendersoftware/mender-connect), and i have seen ProtoMsg structure and the relevant around it. However it s not clear to me how the data are serialized over the websocket connection. This is why I’m looking for the spec 🙂

The goal is to integrate it in my mender mcu client.

Thanks

Joel
