Recently I've come across the suggestion that when you are using the Pixhawk power module, you should snip the (+) wire (middle one) that connects the ESC to the Pixhawk unless you are using a Zener…Continue

@C K:

You should try uploading the firmware again and see if, maybe, your vehicle is DISARMED when the blue lights are blinking.

For further understanding of your problem you could attach your DATA LOGS and someone could take a look into it.

@Chris: Blue light at Pixhawk means it is not locked to satellites but blue light at GPS means it is locked to satellites.

@Esteban: Yes I checked the light's meanings before. Unfortunately the issue is not that apperant to solve.

I started to think that there is a hardware issue. I made tens of different trials and couldn't solve the problem.

C K,

My understanding is that the blue LED does not indicate a GPS 3D fix. Only a green LED indicates a 3D fix. I get a blue LED when I am using flight modes that don't require GPS. Sometimes the LED will change to green anyway when a GPS 3D fix is achieved.

While my Pixhawk was working perfectly suddenly a GPS connection problem started. I can see that my GPS is fixed to the satellites because it's blue light is flashing. But Pixhawk seem like it doesn't conect to atellites because it's blue light doesn't turn to green. 

Maybe it is a hardware problem??

I will be greatful for any help.

Hi everyone, I would like to know if i can use a Qground firmware to build a VTOL and use the mission planner to mapping? Cheers

There is no price difference between the 1MB and 2MB versions.
It's just an updated chip.

Pixhawk 2 alpha versions shipped this week, so we are not far off.
