external IMU chapter 18 & 19 of manual
  • Hello, i have installed late beta software and i would like to use my Pixhawk 2.1 as an external reference to use as an aid for the gimbal.

    What i don't understand is what i need to enable to make it work, do i have to enable both connections? External IMU sensoe AND mavlink connection to my Pixhawk or just connect mavlink to my pixhawk and it'll be used as an external imu too?

    Since i am experiencing a problem with mavlink (it stops working after a minute or so) i am just wondering if maybe i am making a mistake connecting my flight controller in both ways on same serial as an external imu and as a flight controller.

    I went trough the instructions a number of times but it is still not clear to me what needs to be done.

    Basicly, what i am referring to is chapter 18 and 19 of the instruction manual, and since i want to have my flight controller to help, do i need to connect the FC in both ways as described in chapter 18 and 19 or just like in chapter 19 with mavlink and i am done?

    regards,

    Corrado
  • Hello, problem gets worse. Mavlink connects and looks like it is working ok, than all of a sudden it hangs up and no data come trough the serial.

    It looks like it hangs whenever i try to send a mount command from the mission planner. Actually it looks like it hangs even if i do nothing but issueing a command crashes it instantly.

  • Hello!

    You need only a Pixhawk connection via Mavlink. Once you set it up, you select the "MavLink" in the "External IMU type" to use a correction from it.

    "Hello, problem gets worse. Mavlink connects and looks like it is working ok, than all of a sudden it hangs up and no data come trough the serial."

    - try to use the latest beta firmware 2.68x. I remember such problem was in intermediate versions, but currently it is fixed.
    If the problem still exists, please write a bugreport to our support service, we will check it more detailed.

  • We tested latest software beta and still experience hangs on mavlink, sometimes it stays up for up to a minute, sometimes it locks in few seconds.
    My collegue opened a bug report on the site, thanks for your help.
