How to use UDP to send "000190" to local Arduino hardware?

Hello,

TL:DR I need a simple way to send "000190" with UDP to a local Arduino in Objective c. I do not have the hardware to test.

Longer:

Do you have a rec for a library?

Here Is what I have tried: GCDAsyncUdpSocket, and a simple example called UDPEchoClient

I do not get any received log results of course since the server is not available to me so I tried finding an open test server, I also tried running a local server using netcat (all new to me).

Any assistance or direction would be appreciated.

PS I ordered an Arduino for myself to be able to test but it has not arrived yet.
