Unexpected subscribe message

[rob42]

BTW getting all /vessels/self/ data could result in a lot of data. Would be better to ask for the data thats actually required.

It connects to delta stream using: ws://host:port/signalk/v1/stream?subscribe=none

Spec for streaming api says.....
You can specify the contents of the strea by using the subscribe query parameter.

• ws://hostname/signalk/«version»/stream?subscribe=self
• ws://hostname/signalk/«version»/stream?subscribe=all
• ws://hostname/signalk/«version»/stream?subscribe=none

So this is a valid connection query string according to the spec.

Upon successful connection it sends the following subscription requests:

        let aisSub = {
            "context":"vessels.*",
            "subscribe":[
                {"path":"uuid","period":10000,"policy":selfPolicy},
                {"path":"name","period":10000,"policy":selfPolicy},
                {"path":"communication.callsignVhf","period":10000,"policy":selfPolicy},
                {"path":"mmsi","period":10000,"policy":selfPolicy},
                {"path":"port","period":10000,"policy":selfPolicy},
                {"path":"flag","period":10000,"policy":selfPolicy},
                {"path":"navigation.position","period":10000,"policy":selfPolicy},
                {"path":"navigation.state","period":10000,"policy":selfPolicy},
                {"path":"navigation.courseOverGround*","period":10000,"policy":selfPolicy},
                {"path":"navigation.speedOverGround","period":10000,"policy":selfPolicy}
            ]
        };
        let selfSub = {
            "context":"vessels.self",
            "subscribe":[
                {"path":"navigation.*","period":1000,"policy":selfPolicy},
                {"path":"environment.wind.*","period":1000,"policy":selfPolicy},
                {"path":"notifications.*","period":1000}
            ]
        };  ```

So not sure where `playbackRate` would come into it.... that would be a history API query...

Looks like my code added default playback and startTime - oops. So ignore that.
Ok, I was handling 'all', Ive added 'none' now, and will look at 'self' too. Long time since I looked at that code :-)

Seems there is another ws bug in my code that was affecting the above too so closing this.
