QE2 Configuration

Before configuration, ensure that the connections are correct. Use QGroundControl as the ground control station. This configuration applies to scenarios in which one remote controller controls one device:

1. Remote Controller and UAV Status

Both the remote controller and the UAV are powered on. Connect the computer to the remote controller using an Ethernet cable.

2. QE2 Remote Controller Configuration

Ethernet Configuration

Set the computer's local IP address to 192.168.1.123, the subnet mask to 255.255.255.0, and the gateway to 192.168.1.1.

3. Ground Unit Configuration (Configuration for Reference Only)

Open a browser, enter the default address 192.168.1.200, and press Enter to access the LQ management page. Enter the administrator account: admin and password: admin to access the web management system. For the network and wireless settings, set the ground unit to AP mode and set its ESSID to match that of the air unit. Click "Save," and then click "Restart." Serial port data configuration: Configure the serial port used by the remote controller's video transmission unit. Enable serial port 2, enable the client, set the baud rate to 115200, set the target air-unit video transmission IP to 192.168.1.201, and set the port to 1120. After completing the configuration, save the settings and restart the unit.

4. Air Unit Configuration (Configuration for Reference Only)

Open a browser, enter the default address 192.168.1.201, and press Enter to access the LQ management page. Enter the administrator account: admin and password: admin to access the web management system. For the network and wireless settings, set the air unit to STA mode and set its ESSID to match that of the ground unit. Click "Save," and then click "Restart." SBUS serial port parameter configuration: Enable serial port 3, enable SBUS and the server, set the baud rate to 115200, and set the port to 1120.

Serial port data configuration: Enable serial port 1, enable the client, set the baud rate to 57600, set the target IP to 192.168.1.123, and set the port to 8080. After completing the configuration, save the settings and restart the unit. 5. How to Determine Whether the Devices Are Connected Successfully

Physical inspection:

The LQ3 unit has a built-in signal indicator. When the LQ3 indicator remains steadily lit, the devices are connected successfully. When the indicator flashes, the device has no connection.

Web page inspection:

Access the primary device through the Ethernet port (IP: 192.168.1.200): Click "Online Information" in the left navigation bar to open the network settings page. Check whether "IP Address" lists both the primary-device IP and secondary-device IP, which are 192.168.1.200 and 192.168.1.201 respectively, and whether the status information for both devices is Online.

With the Ethernet cable connected to the primary device (AP device): the secondary device's web page can be accessed (i.e., 192.168.1.200). With the Ethernet cable connected to the secondary device (STA device): the secondary device's web page can be accessed (i.e., 192.168.1.201). Ping command inspection:

On the computer, use the ping command to test whether the primary-device IP and secondary-device IP can each be reached. If both can be reached, the two devices are connected successfully.
