Hi,

What is an easy way to transmit some bytes (possibly text) from 1 PIC to another wirelessly? I don't need fast speed, perhaps 1200bps or even slower will do. I am trying to find some cheap FM transceiver chips and use them to transmit/receive RS-232 data using the PIC UART module but can't find any.

Have a look at nigel goodwins tutorials.
There is a tutorial all about rf comms.

Thanks, I have had a look, but the tutorial does not explicitly specify or recommend which RF modules to use. Any recommendations for cheap modules is appreciated.

It specifies the ones I used, didn't you check the hardware page?.



But it should work with any similar modules, just check the voltage requirements.
 
Thanks Nigel. I missed your hardware page. I was looking at the tutorial page and download the ZIP file of the tutorials only. Will try to look for these RF modules in my local electronics shop.
