WIFI-Bluetooth USE

WiFi

WiFi Connection

  1. Edit the WiFi configuration file using vi or nano editor

    vi /etc/wpa_supplicant.conf 

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

    network={
    ssid="luckfox"
    psk="12345678"
    key_mgmt=WPA-PSK
    }
    • ssid: Name of the wireless network

      psk: Password of the wireless network

      Modify according to your actual wireless network name and password. No need to change other settings.

  2. If you want to switch WiFi networks, you need to restart the wpa_supplicant service:

    killall -9 wpa_supplicant 
    wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
  3. Connect to the wireless network.

    udhcpc -i wlan0

WiFi Speed Test

  1. On the virtual machine or host

    iperf3 -s -i 10 -p 5001
    • -s: Specifies that iperf3 runs in server mode

      -i: Sets the report interval to 10 seconds

      -p: Specifies the server port as 5001

  2. On the development board

    iperf3 -c 192.168.10.176 -p 5001 -f m -i 2 -t 24
    • -c:指定客户端模式,并设置要连接的服务器IP地址为192.168.10.176
    • -p:指定服务器端口为5001
    • -f:指定报告的格式。m 代表 Mbps,即报告的带宽单位为兆比特每秒
    • -i:指定报告的间隔时间为每1秒
    • -t :指定测试的持续时间为30秒

  • Configure ttyS1 as a Bluetooth HCI device

    hciattach -s 115200 /dev/ttyS1 any 115200 flow nosleep&
  • Bring up hci0

    hciconfig hci0 up
  • Check Bluetooth status

    hciconfig -a
