Your heart device and the app communicate throughout the day. Your heart device sends out a secure signal several times an hour that only the app can read. Most of the time this signal is simply telling the app that there is nothing to report.
Your heart device sends out a signal to the app when it needs to send data to your clinic. The app communicates with your heart device using Bluetooth® Low Energy to get the data, and then sends the data to the Medtronic CareLink Network using the Internet. The app can send data through Wi-Fi™* or the cellular network for your phone or tablet.
When the app’s Home tab says Active, that means the app is ready to communicate with the heart device and the Medtronic CareLink Network.
The timestamp you see on the Home tab of the app is telling you the last time the app detected one of those secure signals.
