UNET - How to listen for StopBroadcastDiscovery() to finish? And can buffer be changed while BroadcastDiscovery is running?
Hi, I'm currently working on UNET NetworkTransport BroadcastDiscovery.
I'm using a modified version of this example.
However, if I call StopBroadcastDiscovery() and ask for NetworkTransport.IsBroadcastDiscoveryRunning() immediately afterwards, true is being returned.
Is this an asynchronous call? If so, how can I get notified about the Discovery having finished the stopping process?
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Also, is it possible to change the broadcast data while the service is running? I tried the following:
Stop()
Change msgBuffer
Start()
, but this resulted in the following error:
Broadcast discovery has been already running. Stop discovery first before repeat this call
Looks like this has also to do with my first question (see above).
edit:
Yep, Start and Stop seem to be asynchronous. If I waitForSeconds between the Stop() and Start() call, it works as expected. However, waitForSeconds is a dirty hack.
I still would like to know, if I can change the broadcasting data without restarting the service and / or if and how I can listen for Stop() to be finished.

I didn't find a way to change the broadcast data while broadcast discovery is running.
But I solved the problem by doing the following:
Prepare buffer with new data
StopBroadcastDiscovery()
while(not stopped) wait a frame
StartBroadcastDiscovery()
This way I can listen for Stop() to finish and then safely Start() the service again.
See code example:
//preparing msgBuffer in advance... then StartCoroutine(RestartServiceRoutine())
public IEnumerator RestartServiceRoutine()
{
if (IsRunning())
{
StopService();
//wait for service to be stopped, before starting again
while (NetworkTransport.IsBroadcastDiscoveryRunning())
yield return 0;
StartService();
}
}
Hope this helps somebody else!
