Hi,
The drone visualized by the 3-axis in the 3D map view goes away intermittently. However the dot in 2D can be still clearly seen and moving. If I restart voxl-portal, I can again see the drone in 3D. Any idea how to fix it?
On the related note, where are the html files of the portal located in the docker/voxl board? Suppose I want to change the color etc., which html/css files should I change?
Many thanks. Warm regards,
Arjun
@Alex-Gardner hi alex! How to go back to the default configuration? We didn’t change actually, not sure why the configuration is looking for different cameras. Many thanks!
@Anubhav smells like a version mismatch problem. Can you also run Voxl-mapper with -d for more info?
@Nishkala please write a more meaningful question so that people on this forum can help you. What are the symptoms? Why do you think it is bricked? What all did you try?
@darwin-keem you can save the map from the web portal. It gets saved on the board at a specific location. You can then copy it and render it in your software.

@Matthew-Booker thank you! 
@Alex-Gardner anyone? Thanks in advance for your answer.
Hi all! I wanted to confirm if the following was true:
If true, why are we not using also the ToF for the localization and VIO? Another related question is can we have vertical apriltags (like on walls) and also re-localize based on them?
Many thanks in advance.
Hi @ahmed-mustahid : I am no expert, but I too get that warning sometimes but the voxl-mapper still works and generates a valid scene. I thought it is just when the camera is blocked or it doesn't have enough features or something like that it displays that warning. I am also curious to learn from the voxl team what this warning means.
@Matthew-Booker However, when I try to save the mesh from the portal, in my compiled version, I get this symbol not found error. Any ideas why it can not find this function and how to fix it? Many thanks in advance.

@Matthew-Booker Thanks a lot!
What works for me is:
voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./install_build_deps.sh apq8096 sdk-0.8
voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./build.sh apq8096
voxl-cross:~/voxl-mapper(master)(0.0.7)$ ./make_package.sh ipk
scp voxl-mapper_0.0.7.ipk root@10.0.1.10:
On voxl 1 board, I added arm64 7 to /etc/opkg/arch.conf
voxl:~$ voxl-configure-opkg dev
opkg install --force-reinstall --force-downgrade --force-depends --force-overwrite voxl-mapper_0.0.7.ipk
Then everything seems to work so far!
