Hi

I will have a look at your chart tomorrow as I'm not in front of a PC just now.

Are you using the FC component or the UART?

Regards

Hello
Okay, that's no problem. I use the UART component.

Hi

I assume you are using one of the super-cheap 433MHz modules available everywhere. These are cheap for a reason and can be a bit of trouble to get working.

You say that your Tx/Rx code works when the UARTS are hardwired together, but not in RF, which would point to the modules. This post may be of help (old forum)

Hi
I use RF modules from HOPERF Electronic, they are not expensive, the receiver module uses an RFM83C integrated circuit. Thanks for the article you suggested.
