Error on OSMAND protocol

Because Ronaldo said:

you don't have to send "GET", you have to send the ip and port of the server...

the timestamp needs to be in Unix format

And then I said that you should ignore his comment.

Ok,

So the right string would be then in my opinion:

GET /?id=9991234&lat=51.6520&lon=3.99932×tamp=2022-03-09T21:17:00Z&hdop=3 &altitude=4&speed=5 HTTP/1.1

Am i correct?

Well i got a bit working.

But it only updates after reconnect.

in Log file i get this message.
