How to enable 4-GFSK on CC1310 (CC2650)

Other Parts Discussed in Thread: CC1310, CC1120

Hi,

I'm wondering how to enable 4-GFSK mode using the CC1310 and SmartRF06 EB. According to the documentation 4-GFSK is supported but in the manual I can only find “GFSK” which in tests appeared to
be 2-GFSK mode ( CMD_PROP_RADIO_SETUP: modulation – modType=1 ).

Can anybody help me with the settings for 4-GFSK?

 

Best regards!

    We have not characterized 4-GFSK yet, only verified functionality.

    Setting fecMode = 9 enables 4-GFSK

    For the time being we can only offer limited support on 4-GFSK

    Thanks for your reply! It's working with two CC1310.

    I still have a problem, since I currently need to work with a CC1120(TX) and CC1310 (RX) together. On 2-GFSK I can received the packages correctly. Using 4-GFSK (with the other settings unchanged in SmartRF Studio) however I receive seemingly random bytes. So it appears to be related to something that is affected by this change from 2 to 4 GFSK (using SmartRF Studio, not sure what might be changed automatically). Do you have any suggestion which register/setting might be responsible? Or something that might be worth looking at?

    Best regards
