Can't get RF to work

Wireless & IoT
1

I recently purchased the 315MHz RF link but have not had any success using it. I am trying to link two BX24 chips together. Right now I am just sending a continuous stream of 'U’s from one to the other. Everything works great with the chips connected with a wire but I just keep getting garbage with the RF link.

I have tried with the chips near each other and many feet away with no difference. I definitely get a difference on the receiving BX24 when the RF receiver is powered or not but I get no difference with whether the transmitter chip is powered or not. Therefore, I think there is something wrong with my transmitter. I don’t have a scope so does anyone have any suggestions of things to try to see if my transmitter is working?

Any other suggestions?

Any help is greatly appreciated.

You need to post more information if you want help.

Your code, schematic, the micro you are using, etc…

I just bought a pair myself and have been reading up on the issue. Lot’s of people having trouble with these and it seems it’s mostly due to misunderstandings. Here’s a link to some discussions on this forum:
