Go to Main Menu > Settings > Bluetooth (Note: Bluetooth is ONLY required for Bluetooth Notifications from the phone. All other communications are handled via Wi-Fi)
Turn Bluetooth on by tapping the toggle. If the Bluetooth toggle is blue, then Bluetooth is on. (Note: Once Bluetooth is turned to ON, the connection process is managed by the MGI App).
Once Bluetooth is connected to a phone it will automatically connect to that phone in the future, if available, and Bluetooth is ON.
