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.

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.

Firmware - What exactly is this? I know that it isn't a piece of code which just helps in communicating with the hardware since it is the device driver's function.
I guess it is something more complex than that. All the time I see firmware updates for my mp3 players and smartphone. In smartphones I see that after a firmware update the OS's version is bumped up e.g., from Ice Cream Sandwich it goes to Jelly Bean (Android). Does this mean that firmware is an alias to OS?
Firmware is just software that is programmed into a device. In the example you used, the OS would qualify being called firmware. In other devices, it could be less sophisticated than iOS or Android, for example, a lot of DVD players and Blueray players have a firmware component, so do smart TV that are Internet enabled and routers, for instance.

I found this post that suggests to use AirServer to capture video from iPhone. Unfortunately AirServer doesn't support iPods (even though I have a 4th gen iPod running iOS 5.0). Is there a way via software or should I get my iPod to connect to a TV and record it there? I have seen that there are some good cables to connect iPod to TV but I lost the link and now can find only suggestion that explains how to do it on jailbroken iPods.. (which I don't want to do).
EDIT (For the one that closed the topic): is there any code snippet that I can use to send the video data from my app to AirServer?

I'm currently doing an internship in a medical laboratory
They want to buy Ipad and medical device connected to it
example: diabet tester http://www.ibgstar.us/
blood pressure monitoring system http://www.ihealth99.com/
I'm wondering if I can code my own application that gets the data from the medical device and then handle it?
thks for your answers
I think they're some step to success it .
At first you need a Hardware solution like said "Mundi".
You need to grab data from device and store them somewhere accessible (like in a BDD with online acces).
And then the iPad application just have to connecte to the data-Source and play with it
The short answer is YES.
There are many ways to get the data into the app via a network. If you would like to read from the device directly, you would have to additionally find a hardware solution.
I'm not sure this applies, but I've seen some really cool medical apps written using Harvard's SMART project. They provide a simple but effective framework, which is independent of the Hospital Information System (like Cerner, Epic, VistA).

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.
