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 |
*) Note that the driver backport might need to be compiled against your specific kernel to work!
Copy the files from the above package or the files you compiled to the root filesystem.
Install kernel-modules:
| Code Block |
|---|
$ 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)
| Code Block |
|---|
$ echo 81 > /sys/class/gpio/export $ echo out > /sys/class/gpio/gpio81/direction $ echo 1 > /sys/class/gpio/gpio81/value |
Interface up:
| Code Block |
|---|
$ ifconfig wlan0 up |
Scan and Connect to Wi-Fi Network
Simple Scan
| Code Block |
|---|
$ iw wlan0 scan |
Connect manually using wpa_cli
Start wpa_supplicant:
| Code Block |
|---|
$ wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant.conf & |
Run wpa_cli:
| Code Block |
|---|
$ wpa_cli wpa_cli v2.6 Copyright (c) 2004-2016, Jouni Malinen <j@w1.fi> and contributors This software may be distributed under the terms of the BSD license. See README for more details. Selected interface 'wlan0' Interactive mode |
Use the scan command to list available networks:
| Code Block |
|---|
> 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:
| Code Block |
|---|
> add_network 1 |
The output ('1') is the network ID used in the next commands:
| Code Block |
|---|
> 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:
| Code Block |
|---|
> select_network 1 |
Will 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.
