MSP430FR5739 with CC1120 using SimpliciTI

Hello everyone

I’m trying to make a communication link between 2x MSP430FR5739 experimenter boards with the CC1120 radio modules using SimpliciTI v1.2.1 beta. I got the bsp files from the porting wiki and added them to my IAR project. The first goal is to toggle a led at the AP with a button on the end device.

Since the CC1120 radio module needed to be manually defined in mrfi_board_defs.h , My first question is: have I done this correctly or did I forgot something? (You can see the code I added below) I remember that it first threw me an error which I was able to fix by changing an interrupt routine somewhere.

Utilizing the simple API functions in my own program the SMPL_Init function returns “SMPL_NO_CHANNEL” which is supposed to mean that no Acces point was detected (while I do have one set up). Does this mean that my radio module is working correctly or does it also return this when the radio module is not configured correctly?

If I use the example application code “AP as data hub”, 2 leds on the acces point light up and 2 leds on the end device toggle indicating that no join has happened.

I’m a beginner with this so any help would be much appreciated :) I’ve also added my own simple application code below, any comments on this would also help.

Cheers!
