core-bluetooth

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 every minute or so. Currently I have: manager = [[CBCentralManager alloc] initWithDelegate:self queue:nil]; NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:FALSE], CBCentralManagerScanOptionAllowDuplicatesKey, nil]; [manager scanForPeripheralsWithServices:nil options:options]; this starts my app scanning for BLE devices and calls this delegate method when a device is discovered: -

The number of questions on SO related to iBeacon and its background capabilities is increasing and there is some confusion on that point. I have been testing the AirLocate project. iBeacon has 2 "capabilities": Region monitoring and Ranging. Region monitoring is limited to 20 regions and can function in the background (of the listening device) and has different delegates to notify listening app (and user) of entry/exit in the region - even if app is in the background or phone is locked. Ranging works only in the foreground but will return (to the listening device) an array (unlimited?) of all

using the BLE with CoreBluetooth (no iBeacon), is there a way to wake app a not running app when the device receives a bluetooth signal? I'm simulating a beacon with the redbearlab's BLE Shield ( http://redbearlab.com/bleshield/ ). Thanks, DAN * UPDATE 03/05/14 * It looks like Apple has introduced a major update with iOS 7.1: now iOS will open your app for you if it detects a UUID that matches your app. The app only needs to be installed, it doesn't have to be running (logic in AppDelegate needed to answer the wake-up call). If the app was running in the background and then closed (I mean here

I'll start with the question. Is the BTLE RSSI a good way to indicate two devices proximity to each other or not? does it only work with small devices like fobs etc? The Issue: I am currently looking at making an app that will use BTLE and allow connections based on proximity. In this regard it is much like the demo app that apple show in the Advanced Core Bluetooth keynote (When two devices are almost touching they then connect). As I understand it the proximity is determined based on the RSSI value when the central discovers the peripheral. When I try this however with two iPads the signal
