CS Configuration - Issues with Movement

Hi,
when I am trying to set up channel sounding, I am looking for the best parameters for CS configuration. The main problem I have is that even with slow movement (1 km/h) and at a maximum distance of 6 meters, many procedures do not finish successfully. There are many wrong data points and the result cannot be calculated. I am testing this in a room.
Does the CS procedure need a higher RSSI level to keep reliable measurements, or are the RSSI values the same as with normal BLE communication enough?


If I use what is in the example cs_ras_initiator, I see a big error rate - the results are not available at all.
If I increase min_procedure_interval to hundreds (for example 3*160), it starts to work quite well - it works reliably, but only until I start moving the initiator a little. Then, I think there is some data loss, and the whole procedures have invalid data.
I do not know if there is a way to make it more robust against movement. Maybe it is also because of a bit worse hardware - I have my own custom boards. I use 1 TX and 1 RX antenna.

Thank you, Jan.
