send UDP packets over LTE from Android

Question

I cannot figure out how to send a UDP packet over a 4G LTE network from an Android app (no WiFi). Does anyone have any ideas or know where I can find some documentation? I need to write two android apps, one client and one server, so that I can send UDP packets with timestamps from one device to the other. This is to test 4G LTE network latency from device to device.

Please help!

Thanks!

You can use the DatagramSocket class:

This should work regardless of WiFi or mobile connection type, although you may find some mobile operators have some restrictions on UDP connections.
