    ekf_invalid.png

    Hi, I have an error with ekf2.
    The local position data status is invalid.
    I'm using PX4 version 1.11.
    Does modified library with changes is necessary?

      @znn ,

      Are you using the ModalAI PX4 "1.11.3-0.0.5" ? https://docs.modalai.com/flight-core-firmware/#v111-change-log

      Or from PX4 mainline?

        @modaltb From PX4 mainline.
        I used Qgroundcontrol and select the current stable release.

          @modaltb I think the basic problem is on the internet.

          I tried

          • opkg install voxl-suite

          and I got opkg_download_backend fail error
          opkg_update_error.png

          and with the following command

          • ping www.modalai.com

          the error comes up.
          ping_error.png

          Is the ekf2 problem related to this internet problem?
          In some forum pages, the microhard radio has to be disable but i'm not using microhard.
          Is there something i can do?

          Here some additional info about VOXL.

              @znn This looks like you are in "soft ap" mode on wifi. You need to be in station mode on wifi in order to get access to the network. https://docs.modalai.com/wifi-setup/#configure-station-mode

                @Eric-Katzfey Thanks, but i've been tried with station mode so far. I'll check again.

                I think the RX part in wlan0 should not be zero, right?

                Thank you for the reply.

                  @Eric-Katzfey The main cause was system image version. The internet problem has solved!
                  now i'll try again the QGC setup.
                  Thanks a lot.
