Unable to start a mission : vechicle is not ready

Are there any other messages showing up? Click on the loudspeaker symbol (next to the GPS symbol) on the top to see all messages.

#3

One other thing to check is if you have a takeoff waypoint as the first mission item.

#5

Aha, low battery. That’s confusing because the battery symbol seems to show 78%.

You could try this circuit breaker to disable the battery checks: https://dev.px4.io/en/advanced/parameter_reference.html#CBRK_SUPPLY_CHK

Have you checked this? Can you share the mission plan that you’re trying?

#12

USB is connected now . that’s why unable to ready getting message I think only sir

#13

Yes USB needs to be disconnected unless you set:

#14

Yes I already disabled USB .

It’s hard to know what happened when and which screenshot happened because of what etc. You need to tell the whole story. What you try and what happened.

And to make the screenshots more readable you might Google how to take a screenshot.

See is you have MPC_OBS_AVOID parameter set to 1.

#21

If you did not have a subsystem prepared for Obstacle Avoidance the MPC_OBS_AVOID should be set to 0.

#25

thank you sir given reply to me .but don’get that parameter

#26

If you can arm it will start a logfile. Could you share that logfile to https://logs.px4.io?
