  • Hello, I have a Pixhawk1 version 2.4.8, I have an issue on reading the Board Voltage, it is 4.2 to 4.3 volts, if I measure on te power connector I read with the multimeter 5V. The unit is new with latest software 4.2.0.
    There is some parameter to tune this value ?
  • Hello, total noob looking for help after online searches failed to resolve my problem. I have a 450 frame with a pixhawk 2.4.8. I can't arm. Mavlink console after "commander check" returns "GPS error". I am in manual flight mode ( GPS not required ) and I believe I have GPS not locked as a pre arm condition disabled. I don't know how to get more information about what the actual GPS error is or how to fix it. Anyone have any ideas?
  • Hello,

    I have a quadcopter with:

    2 Lipo 6s ()
    4 ESC Monster 2000 ()
    4 motors rotomax 80cc ()
    4 propellers

    But when i arm ans start motors, one motor stop spin when i pull thé throttle to max.
    The total weigt of the quad copter is 60kg. The drone dors noté take off even i pull throttle, Elevetor toi max.

    What Can tout advice me :
    Change ESC to 14S?
    Change the 2 Lipo 6s with a 14s battery?
    Change propellers with bigger propellers ?
    What else?

    Best regards
  • Hi everyone !!
    I have question. How can I send pixhawk location to raspi 4. I research this subject on the net and when I see it I have to use dronekit software. Does anyone want to provide additional information?
    Note: I will be happy if you would like to share website to search extra
    Thanks all of you !!
  • Hey!
    I have an octocopter with a 20A ESC and a 10000mAh, 10C, 4S multistar battery. The battery I had has been damaged and I can not find a battery with the same (or similar) specifications. I would like to know if it is possible to buy a battery with different specifications, as I understand; the battery I had, provided 10Ah * 10C = 100A / 8 = 12.5A to each servo, which is correct due to the 20A specification from ESC's. So my question is if I could replace the battery with a 5000mAh, 20C and 4S battery?
    I hope you can help me, I am new about it.
  • Hiiii

    How to send additional analog sensor information from Arduino to Pixhawk?

    What is the best way to do it? Can anyone guide me on how I view sensor data on the mission planner?
    I can measure analog sensor data in Arduino now i want to transfer this information to pixhawk.

    All the Best
    • As a noob with a PixHawk 2.4.8, I would try using a free serial port first. My familiarity with Arduinos makes me lean toward serial interface.
      I understand "companion computers" connect to the USB port, the one located below the TELEM2 port
      Setting that up involves lots of details about communications protocols.

      You can find lots of info about this in the PixHawk documentation available online.

      Relaying data to Ground Control Software, you must arrange getting it transmitted via a Telemetry Transmitter (Radio) onboard the craft
      to a Telemetry Receiver plugged into the device running the GCS.

      My PixHawk starter kit came with 915MHz Telemetry Transmitter (aircraft) and Receiver (ground) radios.
      AKA Sik Radios, so named for the Sik firmware they are flashed with.

      I'm sure there must be a way to get your sensor data transmitted along with the rest.

      You could alternately set up the Arduino with an ESP8266 addon shield, flashed with MAVLink firmware for an extra Telemetry channel on 2.4 GHz (sorta like WiFi)?
      And of course make sure your GCS software runs on some device that has WiFi capablility. Perhaps it's running on an Android tablet?

      There should be enough keywords in this post to help you search for relevant information. RTFM = Read The Fricken Manual Good luck :)
  • Hello guys i have 12 original pixhawk 3dr for sale. Anyone interested?
    • PM sent.
  • I am sure most will say not again, Pixhawk telemetry. I do need help and all can be reassured that I have spent many hours scouring the net for useful information. I am not new at quadcopter flying, I started in 2012 and have progressed through many quad types and flight controllers, at present I have two 450 size quads and they fly perfectly but my big quad gives me problems. Electronically they are all identical.

    So to the nub of the issue:
    Equipment : Tarot 650 quad copter
    Flight controller : Pixhawk 2.4.8
    GUI : QGoroudControl version 4.0.5
    Motors : EMAX MT 3506 650kv
    Props : Various from 10X6 to 12X3.8 CF
    ESC: Racer Star 30A BLHeli
    Computer : iMac
    Tablet for missions : iPad

    I have very erratic take off behaviour which I have mostly solved by adjusting the Tuning Parameters in QGC. Once in the air and settled it flies as if on rails. During the flight I occasionally get confusing audio messages from my iPad re possible failure for motor number 4 generally not a problem but on a number of occasions crashes have resulted. Another message tells that the battery voltage is say 10.4V but the iPad shows 12.3V. So I hope that by accessing the telemetry logs I will find information which may solve the problem.

    Two types of files show up on my computer, in the Logs folder they are .bin files and in the Telemetry folder .tlog. I have looked at the files using APM Planner. Again searches for programs that can show the telemetry on screen have not helped with Mission Planner the only other program for non professionals. The information in the .tlog files is useless to me and loading the .bin files displays:
    Error preparing insertquery: ISBD table ISBD has no column named x Unable to execute statement, which is of no help.
    Can anyone list all the data elements in the telemetry file or point me to where I can read about it. Some help with what programs professionals use to analyse the data would also be very helpful as I am not totally computer illiterate.

Flashing in Pixhawk

Hi everyone,Recently I've got my first pixhawk CUAV v5+. I'm amazed to see one thing that through one USB port only we can flash code and read the logging data. To understand how is it working I started looking schematic but didn't understand anything. Can someone please tell how is that working?
