III. FAQ

1. Why can’t the ground control station software recognize the CUAV X7+ Flight Controller after powering on the devices?

Possible causes and solutions:

– Cable connection issue:

• Check if both ends of the data cable are firmly plugged in.
• Try replacing the cable.

– Driver installation problem:

• If the drivers aren’t installed, download the corresponding version from the official CUAV website.

– Firmware incompatibility:

• In case of firmware incompatibility, use the official upgrade tool to update the flight controller firmware to the latest stable version.

2. What should I do if data transmission frequently interrupts after connecting the SIYI MK15 to the CUAV X7+ Flight Controller?

Steps to troubleshoot:

– Protocol and baud rate check:

• Confirm that the communication protocols (such as UART, CAN) between the devices are consistent.
• Verify the baud rate parameters.

– Interference prevention:

• Ensure that the connection cables are kept away from strong electromagnetic devices (like motors, power modules).
• Consider using shielded cables to reduce interference if necessary.

– Device reset:

• If the issue persists, try restarting the devices or resetting the parameters.

3. Why can’t I use the real-time video transmission function of the SIYI MK15 after configuring the parameters?

Solving steps:

– Protocol and IP address:

• Check if the relevant video transmission protocols (such as RTSP) are enabled in the ground control station software.
• Ensure that the IP addresses of the SIYI MK15 and the receiving end are in the same network segment.

– Power supply check:

• Check if the power cable of the video transmission module is supplying power properly by measuring the voltage.

– Module reset:

• If the problem isn’t resolved, try unplugging and replugging the video transmission module and restarting the devices.
