Guideline 2.5.4 - Performance - Software Requirements
Your app declares support for bluetooth-central in the UIBackgroundModes key in your Info.plist but does not provide Bluetooth Low Energy functionality. The Bluetooth Background modes are for apps that communicate to other devices using Bluetooth Low Energy and the Core Bluetooth framework.
Next Steps
To resolve this issue, please revise your app to add support for Bluetooth Low Energy communication through Core Bluetooth in your app or remove the bluetooth- values from the UIBackgroundModes key.

I have developed a SAMSUNG SMART TV App in development mode. How can I install this app to client TV without using user develop?
I searched a lot in Google but I didn't get any proper solution.
My answer is just for 2012 TV (E/ES/EH) Series:
Unzip your exported application to USB Drive with folder named your apps
Example: SampleApps_1.000_Asia_20140218.zip so resulting X:\SampleApps\config.xml
Plug-on the USB Drive
Turn off the TV
Turn on the TV and go to smart hub
The USB Drive "must" plugged-on when using the Apps because the apps is not installed on TV, just read from USB
This will not work for 2013 TVs as they require a particular signature file generated from Samsung HQ itself.

I need to build an app that controls GarageBand on OS X.
It's an app for iPhone that would control basic functions from OS X GarageBand like play, pause, etc.
I don't know how to build this app, how can I communicate with OS X?. Some friends told me about bonjour, but I have no experience with it and I have no idea on how to use it to build this app and yes I've read the bonjour's page.
Can someone give me some direction?
Your best bet is CoreMidi
https://developer.apple.com/library/ios/documentation/MusicAudio/Reference/CACoreMIDIRef/_index.html
Garage Band speaks midi, and if your app sends midi signals either over USB or some other protocol (like Bonjour to a listening client app) you can interact with GarageBand this way.

I am trying to use Apple's CoreBluetooth framework to connect an iPhone or iPod Touch to a Lego NXT. However, it does not seem like there is any documentation from Apple about this framework at all. Does anyone know how to use it? What the available methods/objects are? Or in general just how to use it.
CoreBluetooth provides APIs only for interacting with new Bluetooth Low Energy (LE) devices. This is a new standard that is not compatible with traditional Bluetooth. The iPhone 4S has a dual mode BT chip that does LE and regular mode. So you will not be able to use CoreBluetooth to talk to traditional Bluetooth devices like NXT. However, in the future it would make sense for applications like NXT to use LE mode Bluetooth.

I am using iOS 4.
I am wondering that is it possible to connect a wireless mouse with iphone via bluetooth? Yesterday I saw a remote access/login to mac pc through the iphone and ipad but its seems hard to operate it as there were no mouse and keyboard.
So, I want to know that is there any way to connect wireless mouse with iphone so it make easy to use when we want to use remote login?
Is there any API that help to develop this kind of application?
In order for a mouse to be available over bluetooth, it would need to be MFi compliant, which requires an MFi authenticator chip in the mouse.
Unless you market an accessory yourself (and receive Apple's blessing), it simply will not work.
You should just try to connect a standard Bluetooth wireless mouse to the iPhone and try, as per the apple supported Bluetooth profiles, the iPhone 4 supports HID profile , which means that Bluetooth wireless key boards and mice should work
See this for reference - http://support.apple.com/kb/ht3647
To do this you either need to Jailbreak your device or make a accessory yourself. No accessory will be able to to use a mouse in apples applications or the home screen unless your device is jailbroken. You can make a accessory yourself but you have to apply for the MFi Program (http://developer.apple.com/programs/mfi/) but developers would have to build the functionality into their app so you couldn't use it on any app.
Regarding the API. It is not possible to use a wireless mouse with a iPad however if you were part of the MFi program you could make a mouse with a 30 pin iPhone connecter on the end which a developer could communicate with.
You should check out the crux loaded. Unfortunately it's for iPad and not iPhone but if you have a iPad it looks awesome. Check it out at http://cruxcase.com/products/crux-loaded-2/. It's kinda expensive :(

I need to develop an iPhone/iPod application which runs in the background and can measure audio output. It is part of a research project to measure how loud people have their music. Unfortunately I am unfamiliar with the iOS 4 SDK.
Ideally, the application would have to know if headphones are plugged in, be able to measure the volume of the audio signal being outputted (and calculate some data) and then be able to, at some point, update data to a central database.
Taking into account the multitasking capabilities, is it possible to develop such an application for the iOS 4?
I am aware that multitasking on this platform is quite limited, however I also noticed that audio processing seems to be possible (only to an extent perhaps?)
Here's a question which shows how it can done, but unfortunately, you can only do it for your app (or more correctly, I should say only when your app is active), you can't add a global hook to be notified in the background when the volume is changed by another app.
iOS (4) doesn't have background services like Android which is what I believe you're looking to do.
