Like many others I just use “MIT App Inventor” to create Android Apps using BlueTooth for Arduino projects but except that it’s far of the Corona power! So, when it will be available?
There are three bluetooth plugins in the Corona Marketplace. One is iOS only, one is Android only, and one works for both:

By searching with Google I found old plugins, abandonned. Thanks, I’m going to take a look 
I tried the plugin by Scott Harrison, the connexion works but that’s all, no example how to send and receive data 
You may need to try one of the other ones.
There is not example on how to send data because it is so simple.
bt.send(“hello world”)
I want to use Scott Harrison’s Bluetooth plug-in.
There is a function that sends data to a technical document. (bt.send)
https://scotth.tech/plugin-bt
However, functions that receive data can not find a description.
I would like to have a sample or information about the function that receives the data.
bt.init(function(e) if e.message then print(e.message) end end)
