Hello, When I was developing Bluetooth communication apps like Arduino, I created this app to test Bluetooth communication simply because I can't test if Arduino breaks down properly.

Thank you!
It looks like this isn't made with App Inventor.
When I made the app, I used many extensions for design.
And how did you change the packagename?
Changed the package name of the file to apk studio https://puravidaapps.com/packagename.php
