Hi,
i'm trying to get connman managing virtual wifi device created using
mac80211_hwsim kernel module.
In this configuration, a scan wifi from connmanctl always return a "no carrier"
error message.
Using gdb, i found that the connman_device is seen as unpowered. Hence, the
test in device.c:610 fails and connmand return -ENOLINK (err code -67).
This does not seem logical to me. Is this a bug ?

This usually occurs when ConnMan cannot forward such request toward
wpa_supplicant. Therefore, I would suggest you to ensure
wpa_supplicant has control over this new interface. For instance,
check you can request for scanning from wpa_cli. If once done you
still get the same error, you should check wpa_supplicant has been
compiled and executed with the required options, see section
"wpa_supplicant configuration" in documentation [1].

Hi,
scanning with wpa_cli is ok. Also, i recompiled wpa_supplicant following the
advice from connman config recommendation (at least CONFIG_BGSCAN was missing)
Now i still have a problem :
"connmanctl> scan wifi
Error /net/connman/technology/wifi: Not supported"
>From gdb, it still is triggered from device.c:device_scan, but because the
>device's driver is null.
i attached here the log from connmand -n -d output.
