Wi-Fi
|
The operation below requires root access. |
UCM-iMX8M-Mini features certified 802.11ac Wi-Fi interface (Broadcom BCM43353 chipset). Before working with Wi-Fi, please, ensure that Wi-Fi antenna is connected.
For hardware setup and Wi-Fi antenna connection instructions please refer to evaluation kit hardware guide.
To start using Wi-Fi insert your network credentials into the following file:
/etc/wpa_supplicant.conf
Insert the network name into ssid field, password into psk field and key into the key_mgmt field (if your network uses key management).
The file should have the following content:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
network={
ssid="<the name of your internet acces point>"
key_mgmt=WPA-PSK
psk="<the password of your internet access point>"
}
Execute the following commands to connect to the network.
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D nl80211 udhcpc -i wlan0
