I have bought 5 BLEs from sensor tag, I Downloaded some iBeacon detection code.
But I do not know UUID of the 5 BLEs. Do I Need to put the UUID in my iBeacon detection code?
How Can I get the bluetooth device list using iBeacon code?
While you can use CoreBluetooth to do an LE scan and see all nearby iBeacons, the info you get back about each iBeacon is not very useful -- iOS blocks you from being able to read the iBeacon identifiers, including the ProximityUUID. See My blog post about this here.
So the bottom line is that while you can see unknown Proximity UUID iBeacon devices with iOS, you cannot even be sure the devices you see are iBeacons at all.
Android and OSX Mavericks do not have this restriction, so if you have access to one of those devices, try my company's iBeacon Locate or ScanBeacon products, which will read your identifiers for you.
Is impossible, at lest no way to get this list via public API, you must know the UUIDs before ranging

I have a Bluetooth device, and I try to execute a function when my application is near the device.
I read on an iBeacon technology, but I did not really understand if the iBeacon could be used on all Bluetooth devices as long as you have your UUID, or you need the Bluetooth device have a service that sends a special UUID for iBeacon?
If you have access to the firmware on your Bluetooth device, it is generally simple to set up iBeacon advertising. You must enable the Bluetooth controller to emit a manufacturer advertisement with a specific 22 byte payload. The details of how you do this is device-dpecific.
That payload contains three identifiers which you may choose, the Proximity UUID is a 16 byte sequence, the major is a two byte sequence and the minor is also a two byte sequence.
You can see the layout of this payload in my answer here.
You can then use the CoreLocation API on iOS and the Android Beacon Library on Android devices to detect the iBeacon advertisement with the same identifiers and make your app react.
I would like to develop app which detects a lot of beacon device withoud knowing uuid.
However I cannot find way to do this in internet.
I have to define uuid in code.
So is there way to detect iBeacon without knowing uuid?
I know CoreLocation requires you to know the UUID of the beacon you are CBCentralManager, which handles all of the bluetooth spectrum. It has methods for scanning for bluetooth devices. I don't have an iBeacon handy at the moment to test and see if it picks them up, but it is probably worth a try.
The nomenclature used is quite important here. If you want to detect 'iBeacon', then you need to at least know the UUID of the device or devices you're looking for. That's because, in the iBeacon standard, the ID is the only piece of information included in the advertising packet. iBeacon lets you do two things: monitoring and ranging (detecting whether there is an iBeacon in range, and detecting how close the iBeacon is), and both require you to know the UUID.
If you just want to look for beacons, without including the iBeacon properties and features, you can use Core Bluetooth to do that. SDKs of particular beacon vendors base their beacon maintenance features (firmware updates, settings changing) on that. This method is also used by vendors that use their own protocols alongside Apple's iBeacon. We do that at Estimote with Estimote Stickers, and AFAIK Gimbal does this as well.

I need to build an application which display the list of available Bluetooth Cameras and need to paired with them.I have search through the web,but unable to find any useful link.
any Tutorials/Sample code would greatly appreciated. !!
Thanks !!
If you are talking about BLE (Bluetooth Low Energy or Bluetooth 4.0) than the answer is YES. You can easily discover BLE devices in your app.
They identify using a specific UUID which you have to know to discover them. You will act as a so called BLE Central, the camera would be a Peripheral.
I don't know any Bluetooth cameras, but if they support BLE, you can refer to Core Bluetooth framework reference or the Core Bluetooth Programming Guide.
If they don't support BLE, but the old Bluetooth, you would have to be member of the MFi Program. To be a member you would probably be a hardware manufacturer and have already products in stores. I also heard of individuals that got accepted, but you might probably not.
Long story short: BLE - YES, !BLE - NO.
i want to know some details about iBeacons. Couple of days back i created a sample project where i turned my iOS Device into an iBeacon and i tracked down that iBeacon with another device, i am also getting the proximity distance between my Device and the beacon.
So my question is Is it possible to post some advertisements from my device which acting as iBeacon?
How to configure that?
All i wanted to know is how the iBeacon Configuration done to send the data?
Some one please help me out
thankYou
An iBeacon "advertisement" is just a constant transmission of a four part identifier that signifies a unique device. It only contains four fields:
proximityUUID (a 16 byte UUID usually expressed in the form 00000000-0000-0000-0000-000000000000)
major (a number from 0 to 65535)
minor (a number from 0 to 65535)
power (a number from 127 to -128)
That's it. You can't make an iBeacon send any more data than that. It doesn't matter if the device acting as an iBeacon is your phone, an iPad, a Mac computer, or a small battery-powered unit.
If you want to tie other data to an iBeacon, you have to do it through another channel, by some kind of lookup that matches the data up with the identifiers above. You can do this with a static lookup table in your app, a web service, or a CoreBluetooth communication channel. But you have to code that yourself.
After searching on Google, I found that people say it's only possible to connect an iOS device with a non iOS device with the 'MFi program'. Is that true?
My project is mainly focused on sending and receiving information with the Arduino device via Bluetooth directly.
Is communication between iOS and non iOS devices without jailbreak possible? If yes, is there a reference?
(I viewed Stack Overflow question How can an iPhone access another non-iPhone device over wireless or Bluetooth?.)
As I stated in the above-linked question, general Bluetooth communication to external devices on non-jailbroken iOS devices is restricted to MFi-compliant Bluetooth hardware.
However, newer iOS devices (iPhone 4S, new iPad) are capable of Bluetooth 4.0 LE communication with external devices without the need for those devices to be MFi-compliant. This interaction is done through the new Core Bluetooth framework, which lets you send and receive arbitrary data to and from Bluetooth LE devices. This only works with those listed newer iOS devices, though.
Tim points out an interesting hack that you might be able to get away with in making your device appear like a Bluetooth HID keyboard. Devices like this barcode scanner have special modes to appear as HID devices to iOS. You might be able to pull something together based on this, but all data transfer will be one-way from your device, and it looks like this will require entering that data into text fields as if you had a keyboard connected.
Alasdair Alan's "iOS Sensor Apps with Arduino" is a good resource to look at. I've used Wifi with another microprocessor (mbed) but not sure about bluetooth. Alasdair is active on Twitter and he usually is kind enough to answer questions.
