Hi, TI

As the SDK doc mention, There are following Channel sounding timing parameters that can be changed. Could you kindly tell us where to change those parameters the car_node sample. Thank you

Hello Chen,

Currently, the timing parameters are within the source code and cannot be configured by the user.

Thanks,
Isaac

Which source code including the timing parameters. Could you tell us what the default value for those parameters? Thank you

Hello Chen,

T_FCS = 150 us

T_PM = 40 us

T_IP1 = 145 us

T_IP2 = 145 us

T_SW depends on the antenna configuration and the T_SW supported by the local and remote device. For 2x2, T_SW defaults to the maximum value supported by both the local and the remote device.

The llCsCapab_t struct in ll_cs_common.h contains the timing parameters.

Thanks,
Isaac

As we understanding ,These parameters are the value in local capablitites and remote capabilities. Now the values used in communication are defaults as you mention . Are these pareametes can be changed by app in successive sdk version?

Chen,

As far as I am aware, we do not plan on providing a way to alter the parameters within the application. I will confirm and get back to you by Wednesday (12/17).

Thanks,
Isaac
