CC2745R10-Q1: [BLE 6.0 CS DKC]Long-duration ranging issue in Channel Sounding

Tool/software:

Hi, Ti

*SDK version: 9.12.00.19

I have been conducting tests on the Channel Sounding feature using the new SDK(9.12.00.19). After continuous operation for 40-50 minutes, I observed that the ranging results consistently report an invalid value of 4294967295, and normal functionality can only be restored by a reset operation.

Could you please confirm if this is a known issue? The test was performed using CC2745 (car_node example) and CC2340 (key_node example) for ranging. The code and test scripts I used are attached below.

Best regards!

    Hello,

    It seems that could be an overflow error related to the python script. I will assign this to a member of my team and they should get back to you next week.

    Best,

    Hello Preston, 

    Is the test environment the same as the previous E2E thread? The environment communicated was 1-10m, with initiator within the vehicle. Testing LOS and NLOS situations? Is this still the case? 

    When you say consistently report, is the invalid result (0xFFFF FFFF, or 429496795) always reported, or are you getting some valid results, but mostly invalid results? 

    Is it possible to capture a sniffer log when the issue occurs? 

    Additionally, a 9.11.01 release will be public by the end of this week. This SDK will include a large amount of CS problems. 9.12 was released to provide the initial SDK for our new MCUs coming to market. 9.11.01 will contain more CS related fixes. I would recommend switching to this SDK when released. 

    In the meantime, please provide a response to the questions above, and let me know if a sniffer log is possible! 

    Thanks,
    Isaac
