Button press count/duration via bluetooth to android!

Projects General Guidance

I would like to send data from an hc-06 bluetooth module to an android app. The data I want to send is button press count and duration of button press. It is for an e-cigarette system.

Any advice on code would be much appreciated. Thank you.
The App is being designed in App Inventor 2

Fisrt see if you can pair the Bluetooth module, then see if you can send a single byte to the app. After that try sending a packet with delimiters. Finally send your data. You should only need maybe an int for the button count and a long for the duration (unsigned)
