DWM3000EVB + nRF52840-DK cannot implement DS-TWR

[OsakaAtsushi]

Hello.

Currently, I want to run DS-TWR with “ex_05a_ds_twr_init.c” and “ex_05b_ds_twr_resp.c” using DWM3000EVB and nRF52840DK. However, if I execute it with the parameters as they are, only transmission is possible, but not bi-directional communication.
When I investigated the cause, I found that it was “Preamble Detect Timeout”.

Even if I increase the delay and timeout values, it is not possible to move to the ranging phase. Are there any other factors? Also, I am using two devices on one PC, do I have to use two PCs?
Please let me know when you have time.
