LP-EM-CC2745R10-Q1: The CC2340 and CC2745 were used to test the channel sounding function, but no valid data could be obtained.

Tool/software:

Hi, TI:

I'm testing channel sounding on sdk 9.10.0.83 using cc2340 as reflector and cc2745 as initiator, but I'm getting invalid data. Please guide me how to set sysconfig and python parameters so that I can get valid distance data.

software and hardware environment: SDK 9.10.0.83，1 * LP-EM-CC2745R10-Q1 board，1*CC2340R53 board,  1 * BP-EM-CS board

The test results are shown below:
