Have attacehd my output from a connect attampt agains a hidden SSID where I
had BSSID in the config. And it didn't connect over the time I looked.
Here is the scan for the area:
SSID BSSID CHAN RATE S:N INT CAPS
OPERAX 00:0f:cb:9f:de:ee 1 54M 37:0 100 ES
0x000000 00:0f:b5:72:a6:56 3 54M 52:0 100 EPS WPA
0x000000 00:09:5b:b8:c4:4d 3 54M 61:0 100 EP WPA
OPERAX 00:15:e9:60:e8:4c 6 54M 53:0 100 ES
jonsson2 00:05:5d:f2:50:2a 6 11M 78:0 100 EcP
and the wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="LCLSSID"
key_mgmt=WPA-PSK
scan_ssid=1
psk="iM03x123"
bssid=00:0f:b5:72:a6:56
}
