I use pixhawk for FCU
I can't find that log, but there was no distance sensor logged as I remember. It was empty
last week I tried lidar+px4flow on APM stack and it worked pretty nice
which means it is not an H/W issue
but APM doesn't support mavros local_set_point command with no GPS as far as I tried
so I'm keep I'm working on LPE anyway.
may be trying through I2C would help?
