Initiate SDK node problem

[dregner]

Hello,

I am trying to connect M210 v2 RTK to a desktop computer with Ubuntu 18.04, ROS Melodic and parallel installation of Opencv 3.3.1 and 4.5.3 using a USB-TTL RS232 to make UART connection and an USB-USB connecting drone and desktop to be able to run Advanced Sensing.

When I call ls -l /dev/ttyACM* && ls -l /dev/ttyUSB* it returns that it is indentified the USB and ACM connection.

crw-rw---- 1 root dialout 166, 0 out  4 13:18 /dev/ttyACM0
crw-rw---- 1 root dialout 188, 0 out  4 13:18 /dev/ttyUSB0

I also set the transfer rate of TTL-USB to 921600 using minicom, and gave persmission to device to read and write with sudo usermod -a -G dialout $USER && sudo chmod 666 /dev/ttyUSB0

Unfortunatelly when I launch roslaunch dji_osdk_ros dji_sdk_node.launch it appears some connection problem presented below and I am not being able to fix it. I have been trying to turn on/off drone and RC several times ass described here, but the problem still stand.

It appears it has some problem providing a udev file, but I don't know how to fix it. Does anyone have some idea to help on this problems?

Thank you!

Dear developer ,

Thank you for contacting DJI.

Please try to run with “sudo roslaunch dji_osdk_ros dji_vehicle_node.launch”, if it works, you can refer to the following to add DJI USB device node. ​ （For M210 v2 series drones, dji_vehicle_node is recommended, If the error persists, please provide the terminal log of "sudo roslaunch dji_osdk_ros dji_vehicle_node.launch"）.

Thank you for your understanding and support, hope you have a nice day.

Best Regards, DJI SDK Support Team

A couple days I was still facing this problem, I ended on this thread explaining the small mistake on yours documentation. After remove the following problem all went just fine. Can you please fix it?

The command there is: SUBSYSTEM=="usb", ATTRS {idVendor} =="2ca3", MODE ="0666" However, the correct command is: SUBSYSTEM=="usb", ATTRS{idVendor} =="2ca3", MODE ="0666"

So, the space between ATTRS and {idVendor} is wrong. Leaving this here in case someone else runs into that problem. Thank you
