4.1 DFS Channel Related Commands

Reset DFS channels state:

echo 1 > /sys/kernel/debug/ieee80211/phy0/dfs_reset

The number is a bitmap:

bit0 - reset all AVAILABLE dfs channels (to USABLE)

bit1 - reset all UNAVAILABLE dfs channels (to USABLE)

Trigger a debug radar detection command on a channel:

echo <num> > /sys/kernel/debug/ieee80211/phy0/wlcore/wl18xx/radar_detection

<num> is the DFS channel number. Ex: 60.

Note:

  • Trying to trigger radar on non-operational channel will results with no command.
  • For 40 Mhz: trigger the radar on the primary channel only.
