CC2652P: Selectin Tx output Power

Part Number: CC2652P
Other Parts Discussed in Thread: CC2652R, CC1352P, LAUNCHXL-CC1352P, Z-STACK, SMARTRFTM-STUDIO, SYSCONFIG, SIMPLELINK-CC13X2-26X2-SDK, SIMPLELINK-2-4GHZ-DESIGN-REVIEWS

Hi,

I have achieved a CC2652P design by RF Start and I'm currently trying to use it. I have a firmware designed for CC2652R and have flashed the CC2652P with it. It's working but the lqi and rssi I get from zigbee packets is too low. Is there any configuration I need in the firmware to get a better result?

Thanks in advance,

Matias

    According to , you should use examples based on CC1352P to run on CC2652P.

    Hi Matias,

    As YK stated you should be using LAUNCHXL-CC1352P (-2) projects to evaluate the CC2652P.  TX power can be selected inside the Z-Stack -> Radio section of SysConfig.  You can also evaluate radio performance using SMARTRFTM-STUDIO.

    Regards,

    I tested the board with the smart rf studio. I get -90dbm Rx RSSI for the CC2652R Launchpad and -100dbm Rx RSSI. Does this mean the board is not working as expected?

    I also ported my custom firmware to cc1352P and the LQI and RSSI values I get from ZB packets is slightly better but still lower than the ones from CC2652R Launchpad.

    Regards,

    Matias

    Hey Matias,

    If you are not getting good results in either SMARTRFTM-STUDIO or SIMPLELINK-CC13X2-26X2-SDK firmware then there could be an issue with your board design.  It should follow the LAUNCHXL-CC1352P (-2) reference design but exclude the Sub-1 GHz RF path.  You can also submit your design to SIMPLELINK-2-4GHZ-DESIGN-REVIEWS for further review.
