Your mobile phone needs to connect to your Revitive via Bluetooth.
The first step in the process is to pair your phone with your Revitive. You must let your Revitive app perform this process. Do not try to do this manually from the phone settings.
Once you have successfully paired, your Revitive will show the Bluetooth icon on its display.
Your phone will now automatically connect to your Revitive when you run the app and your Revitive is in Bluetooth range.
Your phone will disconnect when the app is closed and no longer running (not put in background). It will be be ready for automatic re-connection on the next start of the app. This is good practice as it saves on battery usage.
