OSDK linux/ROS obtains the video stream through the USB for data transmission, troubleshooting steps:
1. Check whether the ACM device is successfully recognized (dual A-USB is connected to the drone and the onboard computer)
2. Using “ifconfig ” check whether the local assigns an IP to the ACM device (M210: 192.168.42.3)
3. Ping the drone IP (M210: 192.168.42.2)
After the ping is successful, test the video stream again.
M300 does not use RNDIS virtual network port, use USB BULK, please use “sudo ” to run sample to ensure access to USB.
