    • RE: FLIR LEPTON 3.5 Thermal camera with VOXL 2

      Hi @Alex-Kushleyev @modaltb @Eric-Katzfey
      I still have the same error when i use my custom board. Could you verify my board pinouts.

    • RE: microhard integration with voxl2, not able to get the data.

      @tom I had an additional query , when i connect the microhard ground module to the windows system, I am able to get the portal on browser through the ip address 192.168.168.100. when I assign the ip to the QGC, it is not loading.
      This was not an issue in ubuntu, in ubuntu the QGC was loading automatically.

    • RE: M0173 dual tracking camera error

      @Alex-Kushleyev, I using voxl2 with M0173 board with camera config 29.
      The errors are now solved, I made the necessary changes and reconfigured every server and pipeline and calibrated the cameras.

      @Alex-Kushleyev
      Yes it is running in the 250k baud rate.
      I did not verify with the voxl-esc tools. I directly connected it to the FC.
      I am using the voxl-fpv-dev version of px4

      Voxl2 is connected to Flight core v2 through telem 1.
      ESC is connected to flight core through telem 2.
      the parameters are the following

    • RE: VOXL FPV Racing 4-in-1 ESC with flight core v2 and voxl2

      @Alex-Kushleyev Thank you for reverting back. I will verify this and get back.

      I changed the firmware version to the voxl-fpv-dev still the FC is not detecting the ESC.

      if i start esc through voxl_esc start , it is starting

      could please verify the parameters I mentioned.
