Hi sansand,

Yes server sends heartbeats every 30 seconds.

So the " task.LoopingCall " I added is correct?

Hi sansand,

I have no idea what is that about and what it is doing :)

Ok. So what would be the best way to keep the connection alive by sending a ProtoHeartbeatEvent in 10 second intervals?

Forgot to say that I'm using OpenApiPy.

Since I can't find anything in the samples, and there's no confirmation back from the server when I send a ProtoHeartbeatEvent, I don't know if I'm doing it right.

I would greatly appreciate an input from the developers or someone that has a working example, how it's supposed to be done.

Hi sansand,

The server does not send any confirmations for heartbeats. If the connection is not dropped and you keep receiving heartbeats from the server, then it means tou are doing it right.

Since the sample https://github.com/spotware/OpenApiPy/tree/main/samples/ConsoleSample does not send a ProtoHeartbeatEvent, do we really need to do it (server keeps sending a heartbeat every 30 sec)? How long until the server drops the connection, if we don't send a ProtoHeartbeatEvent?

Hi sansand,

Yes, when there is no other interaction with the server, you need to send heatbeats to keep the connection alive. If you stop sending heartbeats, the connection will be dropped after some seconds.

RE: ProtoHeartbeatEvent

I have these methods in my app  in python but it never returns anything and the connection drops after 30 seconds, what I have wrong?

    # ----------------------------------------------------------------------------------------    
   def pruebas_loopincall(self):       
       lc = LoopingCall(self.enviar_señal)               
       lc.start(3)

   # ----------------------------------------------------------------------------------------    
   def enviar_señal(self):

       request = ProtoHeartbeatEvent()
       deferred  = self.client.send(request, responseTimeoutInSeconds = 60)                        
       deferred.addTimeout(60, reactor)            
       print("deferred", deferred)
