We use changing advertisement data just fine in our iOS app. Are you keeping a reference to the peripheral that is given to you? you should get a ton of logs. You need to keep a reference otherwise it discards that peripheral as per the docs in the header: * @discussion This method is invoked while scanning, upon the discovery of <i>peripheral</i> by <i>central</i>. A discovered peripheral must * be retained in order to use it; otherwise, it is assumed to not be of interest and will be cleaned up by the central manager.

For my IOS app (on ios8), once it get the advertisementData, it will stay the same, even the data has been changed on the BLE device. How can I get the updated advertisementData in my ios app?

Here is the code, the startScan is called every 5 seconds.

func startScan() { let opts = [CBCentralManagerScanOptionAllowDuplicatesKey:true]; centralManager.scanForPeripheralsWithServices(nil, options:opts); }

func centralManager(central: CBCentralManager!, didDiscoverPeripheral peripheral: CBPeripheral!, advertisementData: [NSObject : AnyObject]!, RSSI: NSNumber!) { println("\(advertisementData)"); }

Here is the output, [kCBAdvDataLocalName: MyDevice001, kCBAdvDataIsConnectable: 1, kCBAdvDataManufacturerData: <11e467f7 7ec2ed>]

the output will never change. how to get the updated advertisementData value?

Thanks, Hank Li
