Connects with the Proximity Band over Bluetooth Low Energy to send and recieve data.


Connecting to the Proximity Band:
Turn on the Proximity Band.
Wait for the LEDs to quickly flash.
Start the Proximity Band Andoid App.
If Bluetooth is not turned on, accept the prompt to turn it on.
Using the "Bluetooth LE Device" dropdown, select the Proximity Band device.
Tap the "CONNECT" button.
If successful, the button text will change to "DISCONNECT".
The app will attempt the automatically re-connect to the last connected device on the next launch.

Setting alarm settings:
Threshold slider: determines how low the signal strength must be for the alarm to activate.
Filtering slider: determines how smooth the filtered signal strength is.
Delay slider: determines how long the signal strength must remain below the threshold for the alarm to activate.

Setting the notification groups:
While the device is connected, notifications are forwarded to the Proximity Band.
Each notification can activate the red, green, or blue LEDs.
To choose which app's notifications will activate the red LED, tap on the red box under "Notification Groups" and select them from the list of all apps on the Android device.
Similarly, the same process is used for the green and blue notification groups.

Turning off the alarm:
In any case while the alarm is turned on, simply press the "Ok" or "Cancel" on the alarm dialog that pops up.
