Okay got it !
As I need to be able to install remote application, I use the AirVantage platform to install it.
But it works the same way as you explained.
When I export my project to an AirVantage Application Package, I need to untar the file to add all non .lua files in it and then re tar it to upload the project to AirVantage platform.
And the app runs well on the RV50.
I will study the code to see if I’m still able to show variable from my lua file to my html file. If yes, I will use that structure in the future.
Thanks you helped a lot !
