Launch app in background when BLE device is in range
I’m making an iOS app to support a Bluetooth LE device. First time the app launches, we pair, but after that I want to communicate with the device whenever it is in range. Using background modes, this works fine for when the app is launched and goes into background and the screen is turned off. But, when the phone is rebooted, the app needs to be relaunched before it will be able to detect the device.
Is there any way to have the app launch in the background whenever the BLE device that it is paired to comes nearby?
