I have these (http://www.seeedstudio.com/depot/433mhz-rf-link-kit-p-127.html) and for the life of me CANNOT get them to work.
The virtualwire library doesn't get past the setup (vw_setup(2000)
function. Has anybody else had this issue?
I'm with you on this one.
I've tried a few different solutions.. one was to hook the arduinos up together, removing the wireless components completely, just to get the arduinos to talk.. I was told they would work fine with the code provided.. but I haven't gotten the receiver end to show that it's actually receiving.
And that's trying both with and without the kit.
Could you post a photo of how you have the tx and rx modules hooked up? And the code you're using? I've used the 433MHz modules from Sparkfun with the VirtualWire library w/o problems.

Turns out, as I first suspected, it was user error, on my part.. No surprise!
I'm not sure where I went wrong the few times I did try to hook it up, but I ended up getting it to work today, just using the example Transmitter and Receiver with the VirtualWire library.
One confusing thing for me,
Transmitter Arduino: Pin 12 to data
Receiver Arduino: Pin 11 to data
Didn't really explain in the example, did a little digging in the .cpp file.
And also, when I had it working today, I noticed with the receiving end, on the breadboard(brand new) , the jumpers were VERY touchy. I never noticed any issues with any other circuits so far.. but if it's not in the right position, it won't receive. (I tried quite a few different parts of the breadboard, same results, along with jumper wires)
But all in all, it's working and I'm excited to see how my coding-newbness works out some lame sketches:D
Best of luck to you!
