B4J Question Continuously receive data from website?

[AmenO123]

I'm trying to receive push messages from the server to the b4j.

I got no luck with firebase so i make a html web that receive the push, but i don't know how to open it with b4j and continuously receive data from it.

With httputils2 i can read the web but to do like i want i should use a timer and set it in 1 seg that will overload the server.

Does it works on b4i instead of b4a?

Yes, as long as the app is in the foreground.
