CC1312R: Getting CC1312Rs radio communicate with CC1120 radio

CC1312R: Communication between CC1312 and CC1200 @ 500kbps

Other Parts Discussed in Thread: CC1200

I'm trying to use a 1312 with an existing radio network that uses the CC1200 @ 500 kbps. I'm using the SmartRF studio with the 1312 LaunchPad and the TrxEB board with the CC1200 as an initial test, but am unable to achieve two way communication at any data rates using the provided profiles or modifications to those. Is there something else necessary for cross device communication between these two chips?

    Have you ensured that following is the same for the two devices:

    - Sync word 

    - Datarate 

    - Deviation 

    - Modulation format 

    Also check that the two devices are sending on the exact same frequency (less than ~10 ppm frequency offset between them)
