Hi, Simon

Yes, you are right. I am picking out the ath-next-test branch which is
using the RFC old patch before that.

By the way, the new submitted patch v2 [1] has taken out the following:

if (mode == SPECTRAL_BACKGROUND)
ath10k_spectral_scan_trigger(ar);

So should we add the trigger command in the comment?

ip link set dev wlan0 up
echo background > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
echo trigger > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
iw dev wlan0 scan
echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
cat /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan0 > samples

Otherwise, I am not able to get any useful data.
