Tool/software: TI-RTOS
We are currently working on the CC1312 project.
This is in progress using the [Node-concentrator] basic example.
I want to change the frequency dynamically when using nodes and concentrator. (921 MHz, 922 MHz, 923 MHz)
To do this, I proceeded with the following settings.
First, I set the value using smart rf studio.

I then used the function below to change the frequency dynamically in the program.
-EasyLink_setFrequency(921000000); //setting Frequency(921Mhz)
-EasyLink_setFrequency(922000000); //setting Frequency(922Mhz)
-EasyLink_setFrequency(923000000); //setting Frequency(923Mhz)
<question>
1. Is there a problem with my settings in smartrf Studio(settings , c files)?
2.Is there any problem using 3 frequencies by simply calling EasyLink_setFrequency? Is this the right way to use ?
3.Is there a function to deinit the RF core? ( I want to use features like EasyLink_deinit() / EasyLink_close )
Thanks
