Topic: Arduino Wifi Shield UDP - sending data (Read 802 times) previous topic - next topic


Hi, Ive been struggling for a week trying to send any data at all from my Arduino UNO + Arduino Wifi Shield to my PC. Ideally, I would like to use UDP, though at this point Im happy with anything that allows me to send information wirelessly.

Ive been through the Wifi Shield examples on the Arduino webpage. Ive tried to send info via TCPIP (client), where I got the blue "data" led on my shield on, but my PC wouldnt receive anything; and I tried UDP, where the led didnt even turn itself on.

Im trying to read the info on Matlab. Any clues on how to work this out? I wish I had some code to show you, but there is nothing. That's exactly what I am looking for, a piece of code as a starting point (to send either a string or a number).
