what should I fill in to replace the <wlan_interface>?

Hi, author. I want to ask a quest that i get a result showed "status: 5, rtt: 0 psec, distance: 0 cm." after i finished all steps.
So, what should i do to solve this problem? Thank you.

After successfully configuring, execute the following command: "iw dev measurement ftm_request conf"

The content of the file "conf" is as follows: xx:xx:xx:xx:xx:xx bw=40 cf=5180 asap
I will receive the following output:
Success to put for target argument xx:xx:xx:xx:xx:xx
Command failed: Invalid argument (-22)

The content of the file "conf" is as follows: xx:xx:xx:xx:xx:xx bw=80 cf=5180 asap
I will receive the following output:
Success to put for target argument xx:xx:xx:xx:xx:xx
Command failed: Invalid argument (-22)

However, I can set it to bw=39, 41, 79, etc., and it works fine. The issue only arises when set to 40 and 80. Still, I can confirm that the bandwidth of my access point (AP) is set to 40 or 80.
ps: xx:xx:xx:xx:xx:xx is ap MAC

I have a little question. Can dell xps 13 provide a nanosecond-level counter? otherwise how did you solve the time measurement problem which as I know is the major obstacle of ftm.
