I am a high school junior and I am attempting to build an autonomous drone for my school project. I have little to no experience with drones, so I am only a beginner.
I am having problems connecting my pixhawk flight controller to Mission Planner on my PC. Whenever I connect, I get the "no heartbeat packet received" received error when mavlink attempts to connect to my pixhawk.
Also, I had a successful connection to the pixhawk a few days back, and even today I can see the pixhawk detected under COM4 port, however, it refuses to connect. The pixhawk boots up fine and I am able to hear the successful boot up sound. I have tried restarting my computer, unplugging all peripherals, and trying multiple different USB ports/cables, but to no avail.
Any help/suggestions would be greatly appreciated!
