Wi-Fi & Bluetooth, Trizeps VIII

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, Bluetooth 4.2, and Bluetooth 5 ready.

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

Install Driver and Power-Up Interface

*) 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

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.
