I have the same problems as lots of people...
referring to this post ( http://arduino.cc/forum/index.php/topic,19577.0.html )
i configured the same boards, sketchs.....but i still can't get anything on the receiver side.
I bought two transmitter/receiver ( so 2 rx and 2 tx) from seeedstudio.
It's written 433 on all 4 parts. They are meant to work together because they are sold together.
I can't believe that they are broken, probably i'm making something wrong.
I tried to connect pin12 from transmitter to pin11 from receiver..........and happily it works,
so i guess i can say that the software is ok. They concerning the wiring i have 0 and 5V on the rx and tx.
What else ?
The antenna is also connected. I read that i must use 300cm antenna, but also 17cm like on this post.
I don't know wich length is correct.
.....if someone can help....
