MRF 24J40 Transmitter

Hi,
I am working on a wireless project. The microcontroller I am using is PIC18F13K22. I want to create a transmitter. I am also using the Zena Analyzer from Microchip.
My problem is that I have the right package structure. But the Payload and Data of the packages are invalid.
I set the initialisation as it is said in the MRF data sheet. I think that it might be a problem of the transmission part or even the package structure. I am not sure.
I would be glad if anyone could help me.
Thanks in advance.

What is your CCS compiler version ?

My Version is 4.114.

#include <MRF24J40.c>
Is this a CCS driver or a Microchip driver you ported to CCS?
Anyway it won't compile without it.

It is only a file I wrote by myself. There are all registers included.

If it's reasonably short, then post it so we can compile your program
and look at it.

I have developed my own drivers for the MRF24J40MA module, and they work perfectly, to get the module working it needs to be initialised correctly only then will it work properly. Read the datasheet and follow the steps given for the initialisation.

Also make sure the receive buffers and the receive interrupts are cleared before issuing the software reset at the end of the initialisation procedure.

thanks
