'IWD ap not starting: START_AP failed: -95

Interface is set to AP mode.

When turning on ap it is giving "Operation not supported".

[iwd]# ap wlan0 start "start_wpa2" password Operation not supported

Output of iwd -d:

src/netdev.c:netdev_link_notify() event 16 on ifindex 5
src/scan.c:scan_notify() Scan notification Trigger Scan(33)
src/scan.c:scan_notify() Scan notification New Scan Results(34)

Using WPA_Supplicant, same AP is able to start.



Solution 1:[1]

Using a different device driver solves the problem, it is problem in the driver, not in IWD. By adding debug prints in cfg80211 and Netlink helps which is making problem.
