You don't post what RF module or a link to it's datasheet.
First thing I'd do is remove the RF modules and connect the PICs together serial-serial and verify taht the code actually works. If it works, then the RF modules are at fault, or the wiring to them, or some other problem... |

Now i tried rf module and its working. I add a button to 877 and led to 628 and when i push the button led is lighting. And I look the data sheets everything is right
I have some problems about Codes. I'm waiting for ideas. |
