- Mon Jun 20, 2016 3:22 pm #49500 This certainly isn't a new topic here...but I can't seem to find any useful examples about how to implement a UDP to Serial Bridge in Arduino. Most of the Arduino UDP examples I've seen have been bidirectional and rely on receiving data before sending it.

I just want to broadcast sensor data so I can later use it with matlab. So I'm wondering if anyone knows any good examples or has written some arduino code for this.

I'm also open to non-arduino solutions if anyone can think of them -> I'm just most familiar with arduino

Thanks

EDIT: Added the code that I ended up using/working for my application. In case it helps anyone. The code is slightly specific to what I was working on, but maybe it can give someone a place to start. The dynamic dns file does the same thing as the other file... just implemented so you don't have to use static IPs.

Maybe take a look at Tardis Time on my project site:

A serial GPS in the attic with the ESP866 AP (open) broadcasts a UDP sentence every second. The arduino code only "culls out" the sentence I specifically want, but I could just as easily send all of the GPS data.

The receiving ESP8266 receives the UDP broadcasts ... I always have 2 clients, sometimes 3. While I am using LCD displays usually, all of that could be cut out and just send to the serial port.

Yeah I've worked with esp-link in the past great stuff. Thanks for responding I figured out what I was trying to do with UDP so cheers.
