Android Question UDP communication - frozen after short time

[petr4ppc]

Dear friends,

please, I am playing with basics of UDP communication.
Everything is OK, but if I send for example each 5 second message (short text) via UDP, then the UDP communication is frozen after short time. Why it is happen? It is possible to secure the communication?

Thank you

What do you mean with frozen?

I change router (I had very old router) and everything is OK

Frozen = that after for example one minute it was not possible to receive messages on both sides (mobile - mobile)

Thank you Erel,
Best regards
