I want to create a one application for communication of card reader with iPhone via dock connector. but problem is there my card reader accessory is not a MFI registered. so i cant get any kind of notification when i connect or disconnect device so please can any one tell me how can i connect or detect Non MFI registered accessory tot iPhone
Thanks.
As you say in your comment, it sounds a little strange(but not impossible) that the reader has the 30-pin-dock interface if it is not "Made for iPhone".
However if you are interested take a look at these refs(only for jailbreak device):
iPhone Serial Port Tutorial and iPhone Serial Communication
Let me know if you want a little more detail, once you figure out what kind of interface you have.

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.
I have been searching and searching, but found nothing yet. Is it really true that there isn't a straightforward way to establish a BT connection from my iPhone to another (3rd party) BT device, i.e. an audio receiver. I know this is possible through the OS (I own a Belkin BT music receiver that works this way - it appears in Settings and from there I can connect to it). Note that I am not interested in pairing to iOS-devices, but an iPhone and my custom made hardware.
I've managed to find Google's BTStack at code.google.com, iBlueNova, Celeste and more, which all must be run through Cydia or similar and also I stumbled upon Apple's MFI-program, which seems fairly complicated.
Does anyone have any experience with bluetooth and iOS, if so, how and where do I get started?
If one might be interested, the project I am developing involves a piece of hardware with a BT device attached on it. The app should be able to send simple commands via bluetooth (basically just ASCII characters) to the device, which will react depending on what it receives.
If you are developing accessories that need to connect to iOS devices and want to use your own communication mechanism then your only option is to join the Apple MFi program.
I want to develop application like this :
http://itunes.apple.com/us/app/paypodd/id341546114?mt=8
I am going to develop one application for credit card reader but i have no idea for connect external device to iPhone. right now i am using ExternalAccessory Class for find connected device but i am not getting any event after connect any Accessory to my iPhone
if anyone has developed this kind of application please provide me the flow
i am really confused..
Thanks .!
Do you plan on producing your own credit card reader for the iPhone/iPod? If so, you will probably need to go through Apple's "Made For iPod" (MFi) program. See: http://developer.apple.com/programs/mfi/
If not, your options for connecting the reader to the iOS device are limited. You cannot connect generic USB or Bluetooth devices -- one of the few devices I'm aware of which gets around this is the Square reader, which is a custom hardware device which communicates over the audio jack. Setting this up likely involved a lot of custom audio engineering on Square's part; it is not an easy task, nor is it something that can be done with off-the-shelf parts.
If you have other plans for what type of reader to use, please add details to your question!
I have researched this to death online and cannot find anything regarding auto launching an iphone app when an external accessory is either paired using BT or plugged into the dock connector.
We are an MFi developer with a BT accessory and application that we would like to launch when paired. We have the Info.plist containing our protocols and the device containing the correct protocol all working and communicating. The application works well with our BT device, however I would like to see the app launch when paired.
I have seen this before with accessories plugged into the connector and would live to know how that is accomplished.

Does iPhone just have that ability for dock connected items to auto start?
I know that the External Accessory framework registers the protocol with the iPhone when the app is installed. This is how the iPhone/iPod knows to take you to the apple store when you connect a BT (or connector) device and you don't have an app for your connected devices protocol.
I don't understand why the app does not launch when paired, I would think this would be a no brainer. Can someone please shed some light on this topic. The best I found is from Apples docs:
Applications that are able to communicate with an external accessory should declare the ?protocols they support in their Info.plist file. Declaring support for specific protocols lets the system know that your application can be launched when that accessory is connected. If no application supports the connected accessory, the system may choose to launch the App Store and point out applications that do."
I cannot understand the meaning by "may choose to launch", does this mean is also chooses to launch? Please help.
The manufacturer of the device needs to include support for this feature at the firmware level. The details of this process are currently confidential by way of the MFi (Made For iPhone/iPod) non disclosure agreement, so unfortunately that is all the detail I can provide. Good luck!
I am wanting to send data over the usb on the iphone and have it captured by my application. This application will be private and not sold. I would also like to just use the standard usb cable that is standard. Is this possible?
This is possible with Apple's MFI Program. The downside is this will probably be quite expensive and you will of course have to develop a piece of hardware that can be sold as a product for your application.
EDIT: If you look at the 'iOS Accessories' section on the MFI Program link above, it suggests that you can communicate over the 30-pin usb dock connector.
