# Using WiFi
|
|
|
|
Applicable platforms: STM32MP157-DK2, STM32MP135-DK.
|
|
|
|
WiFi support is only enabled in the *demo* configurations.
|
|
|
|
The `brcmfmac` Linux kernel module for Wifi is autoloaded, thanks to
|
|
*udev*.
|
|
|
|
You can verify that it has been correctly loaded with the `lsmod`
|
|
command:
|
|
|
|
```
|
|
# lsmod | grep brcmfmac
|
|
brcmfmac 212992 0
|
|
```
|
|
|
|
Then you can scan access points with `iw` command, connect to them
|
|
with `wpa_supplicant`, and get an IP address using the `udhcpc` DHCP
|
|
client.
|
|
|
|
```
|
|
# ip link set wlan0 up
|
|
# iw dev wlan0 scan
|
|
# wpa_passphrase $SSID $PSK > /etc/wpa_supplicant.conf
|
|
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
|
|
# udhcpc -i wlan0 -q
|
|
```
|
|
|
|
Of course, if necessary, Buildroot supports adding network management
|
|
tools such as *Network Manager*, *Connman* or *systemd-networkd*.
