We are currently developing an application that allows Bluetooth connection to hardware devices as well as collecting user health information. When the user is using a device connected via Bluetooth, we can get information from that device and store it via API. We currently want to create a background task that will get device information via Bluetooth every 10 seconds and send it. It will run even when the iPhone is in sleep mode. I have tried many ways, but these tasks will be closed after less than 1 minute when the user sleeps. I don't know if Apple has a separate mechanism for this job or is there a way to implement this feature.
