>Description:
When I try to connect to hidden SSID with wpa_supplicant I get this message from wpa_supplicant:

  14:48:57.988: CTRL-EVENT-SCAN-RESULTS 
  14:48:57.989: CTRL-EVENT-NETWORK-NOT-FOUND 

If I unhide the ssid the connection works.

This my configuration:

armv7# cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1
country=FR

network={
	ssid="mt7612e-4C16"
	scan_ssid=1
	bssid=78:a3:51:26:4c:15
	psk="fUzLoM%UGAkI"
	key_mgmt=WPA-PSK
	auth_alg=SHARED
}


I don't know if this issue comes from wpa_supplicant or bwfm.
