Hello, I attach some photos. The specific sensor is the LV-MaxSonar EZ4 MB1040, tucked away in the data sheet for it is the information that it inverts the serial line, and this is why the inverter is implemented. As demonstrated, it works fine with this if plugged in. I’m not using the ttyOx port, but the ttyS5 port, referencing this as ttyO5 doesn’t work.
Ardupilot doesn’t seem to find it at all, so apmplanner2 doesn’t display or put it in the status bar.
thankyou very much for your help!
