Arming Switch issue in picshawk 2.4 8

Pixhawk
1

Hi everyone, I’m having trouble calibrating my quadcopter using QGroundControl with PX4 firmware (v1.15.4) and Pixhawk 2.4.8. The issue is that after completing the full calibration process, I’m unable to arm the drone — it requires me to press the safety switch, but when I press it, nothing happens. The LED on the switch blinks, but holding the button doesn’t seem to disable the safety.
What’s strange is that when I switch to Mission Planner (with ArduPilot firmware), everything works perfectly. The safety switch functions as expected, and I can arm the quadcopter without any problems. So I know the hardware is fine.
Has anyone experienced this with PX4? Is there a known fix for this in QGC or a parameter I might be missing?
Even though I set that cbrk_io safety to 22027 nothing happens , I only listen to the picshawk consecutively blinking thrice

I am also experiencing it. That’s probably because some of the safety measures are not met and that’s why it’s not arming here is how I managed to arm my drone although it’s still not taking off.

FC: Pixhawk 2.4.8

Radio: FlySky 6X

  1. Remove the battery from the pixhawk
  2. Turn on your radio
  3. Set the Radio to full throttle
  4. Connect the battery to your drone while the radio is on full throttle
  5. Wait 2 seconds untill it’s fully booted
  6. Press and hold the failsafe switch button on your drone
  7. (Very important) Waint for the buzzer to make a weird sound like is growling instead of beeping
  8. While you are pressing and holding the failsafe switch, reduce the full throttle just a little by -10 %

Then the drone will get in to armed.

If the doesn’t work try it as much as you can. It will finally working.

I have been trying to get my drone flying and I think the pixhawk 2.4.8 is a very difficult FC to play around

Pixhawk 2.4.8 are usually copys/knockoffs and it’s hard to say what you actually have in your hands and whether it will run PX4 properly. That’s why they aren’t listed as supported.

What do you think is the best FC I could use rather for a quadcopter?
