FD1 Server Messages

A Server message is where the FD1 server sends a message to the client that might be unexpected or out of bound. For example a server might send a message advising it is going to close the websocket shortly.

Most activity is driven from the client, your end, and the server responds. This can be a single request-response, or multiple responses request-response/response/response.

A server generated message uses a request packet, and the "a" field starts with "fn1."

{
a: "fn1.link.link_status",
  v: {
    message: "Server is powering down in 15 minutes",
    ...
  }
}
