Hello!

I found many topics by the key word "cc1310 4 mbps" and now I want to try 1, 2, 4 mbps. I red that in the demo project rfPacketErrorRate there is smartrf_settings_predefined.c. But I can`t understand how do I have to change data rate and choose the modulation 4FSK or 8FSK when there are only CMD_RADIO_SETUP HSM and Overrides for CMD_RADIO_SETUP HSM settings. Can you send me an example file with smartrf_settings for HS mode and explain what parameters should I change to get different data rates? And how to generate smartrf settings in HS mode.

And another question. In the Long Range Mode what is relationship between symbol rate (20 kbps) and data rate (5kbps)? And what maximum data rate can be reached in the LR mode?

    Hi Sergey,

    We only support settings available in SmartRF Studio.

    For LRM the data rate is the actual data throughput. Symbol rate is the physically modulated signals being transmitted over the air. Since symbol rate is higher than rate, it means that each data bit is represented by more symbols. This again means that coding is used to improve sensitivity (range) at the cost of throughput.
