Good day everyone,

I haven't tried it, but maybe there's a way you can incorporate this library to read the data matrix codes: https://github.com/zxing-js/library

    Hi @SS_9757450 , @ClayHelberg ,

     

    I've tried integrating the library with Vuforia Studio but it only works in Vuforia Studio preview, not in Hololens II.

    Link: https://community.ptc.com/t5/Vuforia-Studio/Load-Module-and-Use-Functions/m-p/731439 

     

    I'm still unable to figure it out why it didn't work in Hololens II.

     

    Very appreciate if anyone could help on this. 

     

    Thanks.

      As I said, I haven't actually tried it, so I don't know what to recommend, other than trying to use some debugging tools to figure out what is going wrong on the Hololens. I haven't had to do much Hololens-specific debugging, so I'm not sure how that would work, but I'm sure Microsoft has some guides you can track down if you do some googling.

      You might be able to get some insight if you try loading your browser preview in Edge--I would expect Edge to be more similar to the Hololens HTML/JS engine than Chrome.

      If that fails, there are other data matrix reader libraries out there that you could try instead. If you google "data matrix javascript" you should find some potential alternatives, maybe one of them will work better with Hololens.
