@RoyAzriel Can you just try a fresh SDK install and see if that helps?

The Doodle Labs pinout could be inferred from this cable mcbl-00085

@RoyAzriel I'm guessing that there is a version mismatch somewhere. Can you install a recent SDK from scratch and see if everything comes up fine? And when you say "dev crone" do you mean that this is a custom drone and not one of our products?

@RoyAzriel Does it come up fine after a power cycle?

@daniellee This log shows a normal flight happening in altitude hold mode. RC inputs are coming in and motors are spinning. Was there some issue with the flight this log was captured from?

@voxltester Use any port you like. When you connect to voxl-mavlink-server at port 14550 it will remember the ip and port you connected from and maintain a connection with it.

@voxltester That's what I just explained. Rather than initiate the connection from voxl-mavlink-server initiate it from MAVSDK.

@daniellee I don't see any log files attached in this thread.

@daniellee Ah, okay, now we're getting somewhere. If it is arming that means you see the propellers spinning? Can you send me the log file from px4? (Look in /data/px4/logs).

@daniellee I don't know what that means. If you can see the RC sticks / switches at QGC then PX4 has to be seeing them. What happens when you try to arm the drone from QGC?
