Connect Antenna to the Board ​

At the factory, there is an antenna in the package box for installation on the board. The antenna is needed for WiFi and Bluetooth functions. The installation method is as follows:

Download Corresponding Image ​

Use Network Disk🚀 to download our provided .img image file from the System Image/Buildroot/ directory.

The image used in this document is: TaishanPi-3M-RK3576_Buildroot_AP6256-mSATA.img

Look for the image file with ap6256 in its name, as this chip integrates WiFi and Bluetooth functions.

Flash Image to Development Board ​

Reference Finished Image Flashing to flash the downloaded image file to the development board.

Log in to Development Board Serial Terminal ​

Connect to WiFi Network ​

Check if the wlan0 device exists:

bash
ifconfig

If the wlan0 device exists, it means the WiFi driver is loaded successfully. Start connecting to the WiFi network:

  1. Open the /etc/wpa_supplicant.conf file and modify ssid and psk:

ssid is the WiFi name, and psk is the WiFi password.

For example:

conf
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
update_config=1

network={
        ssid="tspi-wifi-test_5G"
        psk="www.lckfb.com"
        key_mgmt=WPA-PSK
}
  1. Create a /var/run/wpa_supplicant directory:
bash
mkdir -p /var/run/wpa_supplicant
  1. Kill any possibly running wpa_supplicant process:
bash
killall wpa_supplicant
  1. Use the wpa_supplicant command to connect to the WiFi network:
bash
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
  1. Obtain IP address (optional step, if IP address is not automatically obtained):
bash
udhcpc -i wlan0

After successful connection, you can use the ping command to test if the network is connected:

Connect Bluetooth Device ​

Check if the hci0 device exists:

bash
hciconfig -a

If the hci0 device exists, it means the Bluetooth driver is loaded successfully. Scan for nearby Bluetooth devices:

bash
bluetoothctl
power on
scan on

exit can exit the bluetoothctl interface

Connect to a Bluetooth device in the bluetoothctl interface:

bash
pair Bluetooth Device MAC Address
trust Bluetooth Device MAC Address
connect Bluetooth Device MAC Address
