CC3235MODSF: Radio Tool Question

Part Number: CC3235MODSF

Customer has some questions in regards to Radio Tool.  They want to do the following (so that the serial cable isn’t connected to the module while they are performing antenna testing)

    1. Connect the serial cable
    2. Start the tool on the PC
    3. Connect
    4. Start CW testing (or other testing)
    5. Disconnect the serial cable
    6. Run the antenna performance test
    7. Reconnect the serial cable
    8. Stop the CW testing (or other testing)


However, although the PC program indicates that “Tx Testing Finished”, the power consumption of the module doesn’t drop back down.

Also, if I try to go back to “Set Up” and click “Disconnect”, then click “Connect” again, it gives me an error.


If they don’t disconnect \ reconnect the serial cable, everything works as expected (power consumption drops when they stop the Tx test, no error for disconnect \ reconnect).

They don’t know if physically moving the serial cable connection causes some noise on the line, and this throws off the CC3235, or if there’s some other reason for this behavior.

Any suggestion why this might not work?

  • Hey Lawrence,

    I will reach out to our tools team and ask them about this. I'll get back to you as soon as I hear back from them.



  • Lawrence,

    The tools team is out of office until next week.

    But why do they want to remove the usb cable during the test? All certification testing was done with the USB cable connected. The same was done when we did antenna performance measurements with the CC3235MODA.

    Perhaps they can try using the CLI version. See section 9 in the Radio Tool User's Guide. They can specify the duration of the transmission so they won't need to reconnect; although I am not sure if this will resolve the power consumption issue.
