Install Driver and Power-Up Interface

Date Description Download
15.04.2019 Binary Package for Sterling-60 Release 7.0.0.52 & kuk_imx_4.14.78_1.0.0_ga st60_7.0.0.52_rootfspatch_20190415.tar.gz

*) Note that the driver backport might need to be compiled against your specific kernel in order to work!

  • Copy the files from the above package or the files you compiled to the root-filesystem.
  • Install kernel-modules:
$ insmod compat/compat.ko
$ insmod net/wireless/cfg80211.ko
$ insmod net/mac80211/mac80211.ko
$ insmod drivers/net/wireless/laird/lrdmwl.ko
$ insmod drivers/net/wireless/laird/lrdmwl_pcie.ko
  • Enable the Wireless interface ( nPCIE1_W_DISABLE)
$ echo 81 > /sys/class/gpio/export
$ echo high > /sys/class/gpio/gpio81/direction
  • Interface up:
$ ifconfig wlan0 up

Scan and Connect to Wi-Fi Network

Simple Scan

$ iw wlan0 scan

Connect manually using wpa_cli

Start wpa_supplicant:

$ wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant.conf &

Run wpa_cli:

$ wpa_cli
wpa_cli v2.6

Selected interface 'wlan0'

Interactive mode

Use scan command to list availlable 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-2.4G

To connect to one of them, you will first need to create a network:

> add_network
1

The 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 shows 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 1

Will trigger connection to the previously set up network WLAN_EXAMPLE-5G.

The wlan0 interface need to be assigned an IP-address, to have it fuctional. Either through DHCP or manually.

Notes

Enable & Disable 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 WLAN function.
