    Hi,

    If you are using nortos version of rfPacketTx, according to this post:
    e2e.ti.com/.../2288317
    there is a bug with RF_close using nortos (in older versions of sdk).

    To resolve that, please download and use the latest CC13x0 sdk.

    Hi,

    I have not personally used RF_control API.

    For updating frequency at run time, am I correct to assume that you want to do so without calling RF_close and RF_open?

    If so, one option is to update your frequency parameters (RF_cmdFs.frequency, RF_cmdFs.fractFreq, RF_cmdPropRadioDivSetup.centerFreq) and then call RF_runCmd for RF_cmdPropRadioDivSetup and then for RF_cmdFs.

    For the frequency parameters, you should use the respective values given by Smart RF Studio.
