Hey guys, I am working on a fixed wing uav design using Pixhawk 2.4.8 (Please find the configuration below). I can arm the motors and it works fine when connected to PC via a usb cable. But Pixhawk fails to arm once disconnected from PC. Instead of blinking blue, it blinks red when trying to arm.
PX4 ; QGroundControl ; Taranis controller ;
No telemetry device (I do not intend to take the laptop with me for testing)
My concern is I don’t yet know if there are other side affects. But at least I can press the Pixhawk Arm switch (note that it will keep flashing so I just do a quick press), move yaw to lower right and finally throttle up my motors!
