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 have done some research on core bluetooth framework. Successfully setup discovery of peripheral of other iPhone, connect, discovered services and characteristics and write some values. All went well. Surprisingly come to know there is apple MIFI program (need to research on it).
In excitement I ordered iPhoneSE, HC-05 bluetooth module, Arduino Builder's Kit R2 with original Arduino UNO. It took some days/wasted in shipment and decent amount and now it's not working.
I write proper set up/initialization for peripheral and central classes, adopted delegates and I think it's all correct. However I am not able to connect to HC-05 bluetooth module.
Observations:
On a Android device i turned on bluetooth in device settings, HC-05
was able to be discovered, enter 0000/1234 (password as per
documentation). And yes i was able to connect it. It means HC-05 is
not malfunctioning.
On a iPhoneSE iOS v11.0, Setting -> turn on bluetooth. But HC-05 is
not discoverable.
I simply want to be successfully discover and connect to HC-05 module using BLE technology. Then with delegate methods look up services/characteristics and then try to on/off led.
I can provide more info and background if needed.
I need some help and direction so that I can purchase the correct bluetooth module which connect to iPhone, and I am sure I can do it.
Thanks.
To answer above question-
HC-05 will not connect iPhone. Because HC_05 is not bluetooth low energy.
I have used AT-09 from amazon.
I have written complete article how I achieved it here, and challanges I faced with solution.
The HC-05 isn't compatible with iOS.
This is because Apple uses MFi Licensing Program and HC-05 is not licensed.
To get things working go for a module supporting minimal BT Version V4.0 BLE. Even better, BT Version: V4.2 BLE & V5.0 (better range and larger packet-size), if iOS (v11.0) supports it.
I am not going to recommend a specific model, that's what Google is for.
Apple devices under the MFi licensing scheme only support limited profiles.
HC-05 is based on Bluetooth 2.0. What will work for Apple mobile devices (iPhone, iPad) will be those modules that utilise Bluetooth 4.0 or Bluetooth Low Energy (BLE).
I'm trying to determine what functionality I can add to a BT accessory by paying for the MFI authentication coprocessor. For example, could I...
A. Pass location data to the accessory?
B. Push incoming SMS messages to the accessory?
C. Launch my app on the phone from the accessory?
As Dennis mentioned, all information regarding the MFi program is covered under a VERY water tight NDA. However, what can be said is that all devices that connect to the iPad through Bluetooth or the docking connector port are accessed through the External Accessory framework. Documentation on the External Accessory framework is easily accessibly from Apple's documentation pages and can also be easily googled.
Communication with devices through the External Accessory framework is fairly simple once you've established a connection with a device. In short, the process is to find the desired connected accessory from an array of devices, establish a connection session and the session object contains a input and output stream. Data by creating a delegate that with the device and finally, monitor the associated input and output streams which you use to communicate with the device.
Again, the majority of the information associated with MFi is tightly sealed. However, as far as connecting to devices (that you have the right to connect to) is simple, well documented and is easily searchable since the framework is part of the standard, iOS library.
One other note on Bluetooth. There is also a Core Bluetooth framework that is available with iOS 5.0 and up. This is a much simpler framework that you can use to discover and auto pair with Bluetooth Low-Energy devices (which are part of the new Bluetooth 4.0 spec.)
If you are planning on making an iPad application or desire to have a fairly high level of backwards compatibility with earlier iOS devices, I wouldn't recommend using the new CoreBluetooth framework. The reason is because only the iPhone 4S and the soon to be released "New iPad" have the necessary Bluetooth chipset to connect with Bluetooth LE devices.
All Mfi information is under NDA.
It dosent cost anything to sign up and get access to the information , you can do it here.

I've been trying to find examples on communicating with bluetooth devices on iOS and have been coming up short. As I understand it SPP is not yet supported. At the simplest level, I'd like to send a simple 1 or 0 signal to the bluetooth device I'm creating. (It's a bluetooth switch that would turn something on and off). Is there a way to cleverly do this through the HID or HFP profiles?
The short answer to your question is that you can't connect to an arbitrary Bluetooth device you may happen to have, you can only connect to a Bluetooth device that has come through Apple's licensing program (i.e. the "Made for iPod/iPhone" label). From Apple's documentation:
Q: [The External Accessory framework allows] my application to communicate with Bluetooth devices. So why doesn't my application see the Bluetooth accessory sitting next to my iPhone?
A: The External Accessory framework is designed to allow iOS applications to communicate only with hardware accessories that are developed under Apple's MFi licensee program.
So there is no public API for accessing an arbitrary Bluetooth device from within iOS: you have to go through the External Accessory Framework to communicate via Bluetooth, and the EAF's mission is "communicate with MFi devices," not "communicate with arbitrary external devices." A sufficiently ingenious developer could probably hack something in there, but -
it's a non-trivial undertaking
you are spectacularly unlikely to get past the App Store approval process
So there's just not much percentage in it - the effort of doing so is unlikely to reward you.
If there already exists an MFi device that can be coerced into doing something that you want, that's probably your best chance - short of going through the MFi approval/licensing process yourself, of course. If you want to do so, have at it and good luck.
I'm answering this question late because Zeroxide's answer is incorrect (you can use a random Bluetooth keyboard with your iOS device because Apple implemented that connection, which is different from giving you a public API path to doing likewise) and I find Rokridi's answer to be incomplete-though-headed-in-the-right-direction.
Edit: A caveat has since been added to the linked Apple page about Bluetooth Low-Energy devices. So there's a loophole, but it's not a big one because very, very few Bluetooth LE devices have actually been produced as yet.
As far as i know, if your external device is non iOs device then you should use External Accessory Framework to communicate your application with it. Threfore, you external device should be certified by Apple through the Made for Ipod program (MFI). Hope this helps.
If you want to use classic Bluetooth (not BLE), then you have to first PAIR the iOS device to the Bluetooth device (in Settings). If you can't do that then you can't communicate with it with your app.
NO. whether device is MFi certified or not, you can connect device to iphone if bluetooth profile is HFP, or HID's (ordinary profiles. not iAP profile). Think about bluetooth headset or keyboard. does it need MFi mark on it to use? NO. Never.
Is it possible to communicate with an Infrared device (USB Infrared, TV, Mobile Phone, etc) using iOS (iPhone or iPad)?
Well, i know it's possible, since there are many remote/universal remote applications in the AppStore. I basically want to know how?
What are the limitations and
requirements?
What kind of additional hardware is
required? If it's available in the
market?
Which protocols should i know about?
Which iOS libraries can help me in
the process.
Can anyone point me in the right direction. Thanks.
Any devices using IR for controllers are either wifi or have custom hardware that outputs IR signals based off of output from the device. So without using your own hardware, I don't believe this is possible
Infrared isn't unbuilt in iPhone. All those remote apps are wifi based.
The hardware isn't available but there is a hack you can make to the headphone socket.

There is no infrared connectivity within iOS.However there are bluetooth and wifi.Generally you can use bluetooth functionality by importing GameKit framework.Thanks
is there an iOS api to communicate to a paired bluetooth device? Looking for a starting point.
Thanks in advance!

Like ing0 said you can use GameKit. But it depends what you want to do with bluetooth. You can't access the bluetooth PAN by default, and the lower level bluetooth API requires that you sign an agreement with Apple and join the MFi (made for iPod) program to make a hardware divice that works with Bluetooth.

Read up on the GameKit framework. There are some good examples on Apple's Resources sending and receiving byte arrays. This definitely works with other iDevices but not sure about any old device...
