Hi. I have medical app that communicates with bluetooth device all the time monitoring heart rate and oxygen. I set it as background: External accessory communication, Uses BLE, Background fetch, Remote notifications, Background processing. Unfortunately after about an hour max 2 hours it stops communicating with bluetooth device and stops sending data to the server. I know in Android for example if device in similar to iOS background mode but phone plugged into power then app will never be suspended. Is there some way for the app to be always running? We can tell users to keep it powered or always in foreground. Please help.

Hi. I have medical app that communicates with bluetooth device all the time. I set it up to run in background mode ("Background processing"). It works fine if most cases but i noticed that when I start facetime my app suspends. Why is this happening and whats best practice at handling this? Thank you.
