Selected interface 'wlan0'
Interactive modeUse the scan command to list available networks:
> scan_results
> bssid / frequency / signal level / flags / ssid
a8:9d:21:9d:fe:ec 5300 -78 [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP][ESS] WLAN-EXAMPLE-5G
a8:9d:21:9d:fe:e4 2412 -90 [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP][ESS] WLAN-EXAMPLE-2.4GTo connect to one of them, you will first need to create a network:
> add_network
1The output ('1') is the network ID used in the next commands:
> set_network 1 ssid "WLAN_EXAMPLE-5G"
> set_network 1 psk "YourWLANPassword"The 'list_networks' commands show which networks have been set up ( i.e. WLAN_EXAMPLE-5G).
With 'select_network <network ID>' you select the network to which wpa_cli should connect:
> select_network 1Will trigger connection to the previously set up network WLAN_EXAMPLE-5G.
The wlan0 interface needs to be assigned an IP address, to have it functional. Either through DHCP or manually.
Notes
Enable & Disable the WLAN function of the Device
GPIO3_17 ( GPIO81; see Using a GPIO in Linux) can be used to enable and disable the WLAN function.
Set GPIO high to enable; set GPIO low to disable the WLAN function.
