I worked on detecting nearest BLE 4.0 ios devices using corebluetooth by referring this link
http://olesitune.mine.nu/blelogg/?page_id=180
It's not detecting any ios device.can anyone provide some information regarding this.
Thanks in advance
Are you using iOS 6? Only iOS 6 has support for setting the iOS device as server/peripheral. Remember that you can not discover any BLE devices from iOS just using the standard bluetooth settings, you have to write an app for both sides of the communication.
That guide will not help you discover any iOS devices, only standard BLE devices like heart rate monitors, temperatur sensors and such if you don't have an iOS6 device which is configured as a peripheral device.
I see that you have also posted this question elsewhere, but please submit some of your project code, results, debug data before expecting any helpful answers

I've been looking into adding a feature to support input from a blue tooth device for my iphone application. From what I've found in my research, most people point to using the GameKit FrameWork. The issue here, is that it only seems to support Iphone -> Iphone connections.
Most of the documentation or questions I saw were between 1-2 years old, perhaps something else has been released?
Have you checked the Core Bluetooth Framework by Apple?
It's working for iOS 5+
I have a device that broadcasts data via bluetooth. It is MFI certified and I already have an application on the AppStore that communicates with it, using the External Accessory Framework.
The problem is that my application assumes the device is already paired.
Is there a way to enumerate all such devices within reach and allow the user to select (and therefore pair) to one of the devices in the list?
No, you can not do this unless two criteria are first met.
Your device must be a Bluetooth Low-Energy device.
The device must have the Bluetooth 4.0 integrated chip which, at the moment, is just the iPhone 4S and the New iPad.
These devices, if operating in the low-energy mode, can be discovered and paired through the CoreBluetooth framework. There is no walk-through form of documentation on this framework, but if you are a seasoned iOS developer, you should be able to figure out how to use the framework through the cut-and-dry framework docs.
As mentioned, information regarding the MFi program and hardware development is locked down under an Apple NDA. However, the information regarding pairing to these devices in this manner is readily available through information in Apple's own documentation.
In IOS 6.0, they introduced showBluetoothAccessoryPickerWithNameFilter:completion:
I haven't had much success with it (when it does find devices, they become lost a few seconds later, but this may be an issue with my code).
I want to develop iOS application that is a remote cotrol via bluetooth for the specific product. I try to research related methods for iOS programming, but most people almost said is impossible in iOS. I know iOS allow communication between iOS devices and iOS devices via bluetooth and also support some bluetooth control iOS. But I want to develop iOS application that can control non-iOS device via bluetooth.
It is possible - The non iOS device must be an apple approved accessory or MFi Compliant
It is possible if Jailbreaking is an option: you can use BTstack.org to use RFCOMM & L2CAP to talk to remote Bluetooth devices.
I am an Android developer and .Net developer and not yet have acquired the needed knowledge regarding iOS .
I did a search on-line but couldnt get conclusive answers to several questions I have which are the following :
1.iOS Bluetooth , do I have to use the Bonjour or Game Kit or can I access a lower level API.
2.Do currently I have an option to perform pairing between an iPhone device and an Android device ?
3.Can an application access the iPhones MAC ID and Friendly ID Bluetooth slots and change them while its in the background ? Or while the device is sleeping ?
4.Can an application set if the iPhone is discoverable or not discoverable to other devices - not iPhone ? Can it perform it while in the background ?
Regards !

This might be helpful to you: How can an iPhone access another non-iPhone device over wireless or Bluetooth?
Generally, there is NO option to communicate with non-iOS device via bluetooth in regular iOS API. GameKit is intended for using between only iOS devices. However I don't know the lower level API which open to only licensed accessory hardware developer except acquiring the license is incredibly hard differently with software license.
1) You can only get to the base API if you are developing specific hardware and are a MFi member. http://developer.apple.com/programs/mfi/
2) Don't think so. But Not really sure
3) You want to change the mac id in the background? Not that I know of. Also it seems like a really questionable idea.
4) Again don't think so. Maybe with MFi but I don't know.
I have been looking for a way to show the iPhone screen (not the simulator) on a monitor or projector for demo purposes.
Previous SO post suggested jailbreak (Veency, iDemo/DemoGod, screensplitr) or simulator.
Release notes iOS 3.2 (External Display Support) and iOS 4.0 (Inherited Improvements) mentions that it should be possible to connect external displays to iOS 4.0 devices.
Is it now possible to demo an iPhone device on a monitor without using the simulator, or are the release notes about other improvements?
Anyone tried to display an iOS 4.0 device on a projector or monitor?
Update 22.Jul.2010:
To mirror iPhone screen: Jailbreak
and use Veency, iDemo or
screensplitr
To output to
external device from your
application: Implement External Display Support in your app in iOS
3.2, 4.0
Update 15.Apr.2011 ;))
It is now possible to mirror iPad2 on a monitor
Update 1.Dec.2011:
It is now possible to mirror iPhone 4S on a monitor
The iPhone 4 supports the VGA adapter that launched with the iPad. Within your application, any external display appears as an additional UIScreen instance. You can create a UIWindow, associate it with the UIScreen, and place content there that you would like to have displayed on the secondary monitor.
I show how to do this in the video for the iPad session of my course on iTunes U, and provide some code for this in the course notes. Matt Gemmell also has a nice writeup on the subject.
http://code.google.com/p/iphoneos-screen-mirroring/ Has code to allow you to mirror your screen using the cables mentioned above. This code uses private apis so make sure you don't ship with it. This can be done by creating a new target in xcode and conditionally compiling the mirroring code in.
Check Apple Composite AV Cable and Apple Component AV Cable. These connect to a TV and computer so may be you can find a way to get it on a projector.
Since iPad 2 "The Apple VGA Adapter mirrors exactly what you see on iPad 2 so that everyone in the room can enjoy it." Same hardware that needs special coding on original iPad then on iPad 2 by default mirrors.
If you are using a smart TV as a monitor, you can use the AirPlay function. However, not all Smart TVs support this function. You can simply test it by connecting your iPhone and TV to the same network to see if you can use AirPlay. If not, you can try MirrorMeister's free mirroring app, it works on all iOS and macOS devices as long as you connect to the same Wi-Fi.
