Hello,
I tried to make the laptop communicate with px4 via usb cable. I have installed the noetic version of ros and the corresponding mavros. i have completely updated all packages to the latest. But for some reason I can’t communicate properly using the default px4.launch. It always worked previously. I’ve forgotten when it started not communicating properly. Here is the log output from the terminal. what does this usually mean? It seems that it just can’t communicate with my laptop, but it can communicate with an arm board with the same settings.
