Wi-Fi & Bluetooth, Trizeps VIII Mini

H&D-Wireless Wi-Fi Module

The Trizeps VIII Mini is available with H&D Wireless SPB228 Wi-Fi Module.
It includes a powerful Marvell 88W997 chipset capable of 802.11 a/b/g/n/ac, 2×2 Wave2 MU-MIMO, Bluetooth 5 Classic and LE.

Please also view the documentation from H&D Wireless regarding implementing the driver into the OS.

i.e. for Yocto

H&D Wireless supplies a Yocto-recipe.

  1. Unpack meta-spb228-pcie-uart-32.tar.gz to your <project-dir>/<build-dir>/sources/-directory.
  2. Add
    BBLAYERS +=  " ${BSPDIR}/meta-spb228-pcie-uart-32 "

    to your <project-dir>/<build-dir>/conf/bblayers.conf

  3. Run bitbake

Power-Up Interface

$ ifconfig mlan0 up

Scan and Connect to Wi-Fi Network

Simple Scan

$ iw mlan0 scan

Connect manually using wpa_cli

Start wpa_supplicant:

$ wpa_supplicant -Dnl80211 -imlan0 -c/etc/wpa_supplicant.conf &

Run wpa_cli:

$ wpa_cli
wpa_cli v2.6

Selected interface 'mlan0'

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

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 mlan0 interface need to be assigned an IP-address, to have it fuctional. Either through DHCP or manually.
