Wi-Fi & BT, Trizeps VIII

  • In progress

    • Laird 60-SIPT Wi-Fi Module

    The Trizeps VIII is available with Laird 60-SIPT Wi-Fi Module.
    It includes a powerful Marvell 88W997 chipset capable of 802.11ac, 2×2 MU-MIMO, BT 4.2, and BT 5 ready.

    Please also view the documentation from Laird regarding implementing the driver into the OS.

    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 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 out > /sys/class/gpio/gpio81/direction $ echo 1 > /sys/class/gpio/gpio81/value

    • 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 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:

    > 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 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 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.
