When I use UDP broadcast on local network (192.168.1.255) there are a lot of package drops in our Oculus Go receiver and delta time between incoming packages goes up to 200ms.
I can send 60Hz UDP unicast data to Oculus Go and receive it without problems (Unity 5.6.5p4).
Used UDP broadcast in the past on GearVR Note4 (Android 4.4) where it worked out of the box with our Unity receiver.
Tried the Android multicast lock approach suggested at [1] but it did not help. Logged the lock state every 5s and the multicast lock is being held during application run time. But still the same package problems as before.
Is there anything else which needs to be done on the Oculus Go Android side to receive UDP broadcast without package drops/delays?
Thanks a lot for following up on this. If needed, I can send you data capture plots and used tools (Unity project and C++ test UDP sender).
Forgot to mention that we previously also observed the same issue when we used the Samsung S7+GearVR so I have the feeling that the issue is on the Android side of things.
