  • VaNDAL_UK: atomiclama: I was pricing up the cable 0.08 copper wire and SMA connectors came out to about £15 and I could have made 5 meters worth of antennas!

  • hoverfly: Betaflight RC1...Interesting  if you go to the O.S.D  settings and then change the font  by lining up the icons in the correct precise order then hit  enter,...... It opens up the  O.C.D.  screen. :smiley:

Pixhawk PX4 No GPS LED
« on: October 10, 2017, 11:31:50 »
I';m a DJI user, and very new with Pixhawk etc, chose it because it seems allot cheaper than DJI flight controllers.
I bought a setup from here:
Which comes with pretty much everything for the flight controller it seems, I';ve got it running with bare bones at the moment.
Connected GPS, bat monitor, and reciever. I can connect to it in mission planner, and the Transmitter and RX work fine. Motors spin up etc, the only problem I have which might be related to the GPS is that it keeps flying forwards.

I picked it up, carefully and span the motors at half throttle to see whats going on, I move the right stick forwards - This should make the quad tilt forwards however for some reason it keeps tilting on the front right motor. Seeming like its in a + orientation however in mission planner its set to a X frame not a + frame. The GPS and Pixhawk board are both facing forward on the flat surface of the drone. Its only a little 250 type.

The GPS has no LED, and yes its connected correctly to the 12v power and the GPS socket on the Pixhawk board, the first time I powered up via USB the GPS blinked, after installing the firmware in the Mission Planner it no longer has an LED on the GPS. Nor can I see any GPS fix.

Whats going on?

Hard to diagnose remotely, but I would reset level and check motor order.

I';ve reset the level, re-calibrated orientation, checked motor order however still no luck. Now it wont even arm, Battery is fully charged 3S 3000Mah. And it keeps displaying board voltage low??

There is a new firmware available which may have some bug fixes for the PX4, I suggest a full erase and re-flash. ~~
Why use 4 motors when you can use 6?
