I am a newbie with PX4 and drones in general. I have a quad frame, with Pixhawk flight controller.
Initially I was using Mission Planner and after setting up the flight controller I would take it out to fly. I would press the hardware safety switch which came with the flight controller, and arm the drone while moving throttle stick in bottom-right position on my RC. This would arm the drone and motors will start spinning.
Now I am trying the same with QGroundControl but not able to arm. I see that it only gets armed/disarmed if the flight controller is connected to QGC. Even pressing the hardware safety switch won’t do anything if drone is not connected to QGC. I have setup aux arm channel and a switch on my RC as well. But it only works if the drone is connected to QGC, otherwise I see red light blinking thrice on the flight controller.
My questions are these:
- Is it the case that I need to keep drone and QGC connected, via say a telemetry device in order to arm/disarm it? I do not have a telemetry module.
- If not, what is the way to arm/disarm the drone? I think there are some parameters to set but I am not able to find them.
