I just bought two of each frequency of the RF Links for a project.
I wrote a simple program on two Arduinos: one sends out serial data every 500ms and blinks an LED, and the other waits for serial data and blinks an LED when it receives data.
The setup works great when I connect the TX to the RX with a wire. However, I can't get it to work when replacing the wire with the RF Links! I have tried several things now, with no luck.
I tried several bitrates. 2400bps which is what is stated on Sparkfun, 2800bps which this guy says he used. I also tried 4800bps and 1200bps just for the heck of it. Every time, when I connect the two Arduinos with a wire it works fine, but replacing the wire with the RF modules doesn't work. I have tried with and without a 30cm wire antenna, and I've tried all three frequency modules. I also tried tuning one of them manually.
I'm running out of variables to try. Has anyone else used these successfully? Thanks for your help.
