Hello all, I’m newbie with px4.
What I want to do is to plot the sensor data of on-board sensors in pixhawk4 with my notebook in real time.
I’ve been trying to stream the log data in real-time using mavlink_ulog_streaming.py with the pixhawk4 connected via usb port.
But every time I try, I come up with the error message of
[Errno 16] Could not open port /dev/serial/by-id/usb-3D_Robotics_PX4_FMUv5.x_0-if00:
[Errno 16] Device or resource busy: ‘/dev/serial/by-id/usb-3D_Robotics_PX4_FMUv5.x_0-if00’
can anyone help me with this problem?
Thanks a lot
