CC1200: After reconfiguration of CC1200 in runtime, transmission stops

Aratrika Kundu

Part Number: CC1200

Hi,

I have configured the CC1200 for 915MHz, with Freq dev of 55KHz and baud rate of 19.2kbps. All my TX and RX happens with this settings. But there is a special scenario in which I have to transmit a packet at 915Mhz with changed Freq dev of 235Mhz and baud rate of 76.8kbps to transmit a certain packet. so i am re-configuring the RF to the second setting in run time and again re-configuring to first setting.

But i am observing that no transmission happens in any of the scenarios transmission doesn't happen.

Is there any particular steps we need to perform to reconfigure the RF in run time? Kindly help me solve this issue.

Thanks,

Hi Aratrika,

Just for some clarification, do you transmit/receive sucessfully if you try using these settings in SmartRF Studio (separately, not reconfigured in runtime)?

Regards,

Zack

Thanks for clarifying. Would you be able to share your code so we can take a look? You can send it in a private message if you do not want to post it publicly.
