We used CC2745R10-Q1 as CarNode and CC2340R53 as KeyNode to test CS in Python demo, but the distance value could not be obtained.How to implement CC2745R10-Q1 and CC2340R53 channel sounding ranging on SDK9.14.10.41? How to set the parameters of channel sounding and ranging? Is the following configuration correct? thank you

Result:

mode 2 no distance:

    Hello, 

    First, what is the preferred_peer_antenna variable within the procedure parameters set to? If you are using 2x2 antenna configuration, you should set this to 0b0011. 

    Second, are you using a CC2340R53 LaunchPad? If you are, the RCL PBEGPO2, and PBEGPO3 PinMux need to be configured differently. These should be set to DIO7 for PBEGPO2, and DIO21 PBEGPO3. 

    Let me know if this helps. 

    Thanks,
    Isaac

    Hi, Isaac:

    Thank you for your prompt reply.

    1.Yes, I am using dual antennas, and the preferred_peer_antenna parameter is also set to 0b0011.

    2.Yes, we are using the CC2340R53 LaunchPad. I have configured the pin PBEGPO2 as DIO7, and the pin PBEGPO3 as DIO21.

    After testing, we still have not obtained the ranging data of channel sounding.May I ask if your test data is all normal? Could you provide the parameters of your CC2340R53 for our reference?

    Thanks
