The MIT App Inventor stores the values (all numeric) with double quotes. The arduino writes to the firebase and stores the values with single quotes. Does it matter? Before I get too much further, should I figure this out?
I read a post about using a web interface - will this mean a re-write of the MIT App ?
It only matters if you have phrases or spaces in your value strings. For example, if you have a tag called data:
data : "content"
will return content
data : "my content"
will return only my
because the Firebase component is expecting a string in the string...
data : ""my content""
which will return my content.
So the choice is yours:
Either get your arduino to send strings in double quotes, or use the Firebase REST api and the web component. There are also a couple of extensions available for working with Firebase Realtime Database
