I'm not sure that's entirely accurate. I believe there might be some confusion about the actual connection of bluetooth between the two devices.
While most if not all pacemakers don't have real time monitoring between the devices, rather instead an interrogation at certain times. I do believe they would still show connected to ones smart phone.
While there might not be data transmission or "syncing" continuously, they would still show a connection while in range IMO.
Would it be possible that when Investigators said the pacemaker app said disconnect from phone that it was referring to the app losing basic BT connection to the device and not actually losing connection while in the middle of an interrogation?
Edited to add: 2:28am seems like a random time for an interrogation to be taking place. MOO
Yes, pacemakers can maintain a Bluetooth connection with a phone app even when not actively interrogating. This allows for continuous monitoring and data transmission to the app, providing patients and healthcare providers with real-time information about the device's status and performance. For instance, Bluetooth-enabled pacemakers, like those using the MyCareLink Heart app, facilitate ongoing communication, ensuring that important data is readily accessible without the need for frequent manual checks and reconnecting to Bluetooth.
