When I try to use this extensions: [https://github.com/sbcshop/pxt-stembit.git](https://github.com/sbcshop/pxt-stembit.git)
I got the following error: [https://github.com/sbcshop/pxt-stembit.git](https://github.com/sbcshop/pxt-stembit.git)
" Hex file is not available - please connect to the internet & try again " error
I want to use the robot in education, but now I cant send any code on it.

This is a bug in the extension. I’ll file an issue on the repo, but for now this extension won’t be usable until it’s fixed.
