Matrice 300 RTK OSDK not working

Open UVA-AMRLab opened this issue 3 years ago • 2 comments

We just got our Matrice 300, the OSDK and the Manifold 2-C. We are trying to integrate everything and get it work with ROS.

  • Matrice 300 rtk
  • Manifold 2-C
  • Ubuntu 16.04
  • ROS Kinetic
  • DJI Onboard SDK ROS 4.1.0

We connected Matrice with (OSDK) and (OSDK with the Manifold) by following the instructions from the user manual. The Manifold can not be powered on together with the Metrice. The power output from the OSDK is around 300mV which is supposed to be 24V. We also tried to power the Manifold with the external power and connect to the OSDK to see if it can get data from Matrice by launching ros launch files. We changed the UserConfig.txt and the dji_vehicle_node.launch accordingly. But when we launch the dji_vehicle_node.launch, we got the "Linker channel Init Vehicle Failed" error, even when the devices were connected via USB. Here is the log:

error

We checked our /dev/, the /dev/ttyUSB0 and /dev/ttyACM0 were not listed there. How can we know the OSDK is powered/working?

Dear developer ,

Thank you for contacting DJI.

Log shows that the seriel port initial failed!

Please check the serial port configuration. And for Manifold 2C, there is only one serial port UART0 for debug port, suggest to use a USB-TLL cable, and the serial name can be set to /dev/ttyUSB0.

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

Best Regards, DJI SDK Support Team
