CC1352P7: CenterFreq modification

Part Number: CC1352P7



I need to modify the RF_cmdPropRadioDivSetup.centerFreq for frequency hopping radio without using RF_close and RF_open commands.

Frequency, power, StartTx/StopTx, etc. are being changed with no problems.

What can you recommend for modification of centerFreq? Can I use any command RF_postCmd()?

Thanks you,


  • Hi Alex,

    When you say you don't want to use RF_close  and RF_open, what is the reason?

    To load a new setup, the radio has to switch on and off.

    If you use RF_postCmd(), the RF_cmdPropRadioDivSetup() command will run the next time the radio switches on.



  • Hi Marie,

    Using RF_close  and RF_open is time consuming (15-20 ms). Could you provide more information please, maybe some examples for changing centerFreq using the RF_postCmd() ?



  • Hi Alex,

    If you're only changing the frequency by a small number, you can use CMD_FS to change the frequency without restarting the radio.

    If you're making a larger jump you can shedule a setup command and your fs and tx command. The setup command will run immediately before the fs and tx commands.
