Hello, We have made an iOS app that sends data from our patch device to the iPhone continuously in the background for our intended purpose(collecting health data) , The patch uses the person hotspot to connect to the iPhone to send the data. According to Guideline 2.5.4: "Multitasking apps may only use background services for their intended purposes: VoIP, audio playback, location, task completion, local notifications, etc. If your app uses location background mode, include a reminder that doing so may dramatically decrease battery life." Which background mode we need to use for running the app in background and can we set the repeated local notifications to inform the user that he need to connect to device ?
