WiFly GSX Breakout Adhoc + UDP

Wireless & IoT
1

I just received the WiFly GSX Breakout.

My ultimate goal is to have the WiFly serve an adhoc network and communicate to a ipod touch using the UDP protocol.

I got this all working with the WiShield from asynclabs.com. But they just shut down their store. (too bad)

So i am now using the TX/Rx on the WiFly GSX Breakout with this driver

I think i got the adhoc part via software working with the code below.

Now I need to figure out how to establish the UDP communication.

WiFly.uart.print( (chOut = Serial.read()) , BYTE);

Serial.print (chOut, BYTE);

Hello Stephan,

do you have any pictures of your setup with wifly gsx breakout ?

Hey!

I am trying to do something similar and was wondering if you had success connecting over adhoc network using UDP.

Thanks,

Hey!

Did u ever figure it out? I would like to know the same thing :smiley:
