Core Bluetooth - constant RSSI updates of in-range devices

Question

I just started with the core bluetooth framework for iOS and I\'m developing an app that needs to constantly scan for BLE devices so that I can retrieve their RSSI number ev

Answer 1

You shouldn't do continous scanning as it is very costly for power. Once you discovered devices you have an array of CBPeripheral objects returned to you. On CBPeripheral you can read RSSI and get a callback when RSSI changes. See the following documentation: http://developer.apple.com/library/mac/#documentation/CoreBluetooth/Reference/CBPeripheralDelegate_Protocol/translated_content/CBPeripheralDelegate.html
