This app is mainly intended to help your "presence detection"-based project. It is designed to automatically connect with your BT module, whenever it is in range. Once you have opened this app, it will start to search your BT module and when it is found, the app will establish the connection with the module.

To make this app work with your BT module, you have first need to rename your BT module to "MYBT" (without quotes). Use AT mode to do this. Then, open your phone's BT menu, pair your phone with the BT module. You will need to enter the passkey first (usually "1234").

When it is done, launch this app and it will automatically connect to your BT module when the module is within searchable range. If the app cannot find the module, it will keep searching it until eventually the module is found.

This app will continuously run in background process nonstop until you exit the app using 'Exit' menu. There will be notification displayed on your phone's notification bar to notify the current status of the app during its running.
