I'm working with the "ExternalAccessory framework". I encountered a problem trying my app on a new iPad Air. When i try to show the bluetooth picker this error appear: CoreBluetooth[ERROR] Cancelling picker as we couldn't communicate with Bluetooth The bluetooth is ON . Picker return this error: Error Domain=EABluetoothAccessoryPickerErrorDomain Code=3 "The operation couldn’t be completed. My app work on every Apple Device, except the new iPad Air. EDIT I can connect and communicate with my device. The problem appear only if i call the bluetooth picker. EDIT 2 the problem appears also with a

I am facing 2 problems related to regular Bluetooth.Here is my code. - (void)viewDidLoad { [super viewDidLoad]; [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(showElements) userInfo:nil repeats:NO]; [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(accessoryConnected:) name:EAAccessoryDidConnectNotification object:nil]; [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(accessoryDisconnected:) name:EAAccessoryDidConnectNotification object:nil]; [[EAAccessoryManager sharedAccessoryManager]registerForLocalNotifications]; }

I am using serial programming for get connected serial cable to my iPhone my code is as under #include <stdio.h> /* Standard input/output definitions */ #include <string.h> /* String function definitions */ #include <unistd.h> /* UNIX standard function definitions */ #include <fcntl.h> /* File control definitions */ #include <errno.h> /* Error number definitions */ #include <termios.h> /* POSIX terminal control definitions */ static struct termios gOriginalTTYAttrs; static int OpenSerialPort() { int fileDescriptor = -1; int handshake; struct termios options; // Open the serial port read/write,

I was wondering, if there is a way to use IPhone as an HID device, with some other device like PS3. I checked out the Bluetooth specification and IOS Devices do support HID Profile. So I thought it would be easy to pair my iPhone using passkey mechanism and should be able to start using my iPhone as keyboard or mouse without much hassle. But I found very soon that this assumption is naive and I need to develop custom solution. I was initially thinking about using GameKit framework, but I think it only works between two compatible IOS Devices. If I want to extend this capability, then I have to

I've been trying to read data from a device via Bluetooth 2.1 using an RN-42. The device pairs to an iPhone or iPad Mini, and data is streamed across briefly, but the iOS & BT module disconnect (unpair) within seconds (less than 10). The device is outputting data 5-10kB/s, so well within Bluetooth’s spec. Something that I’ve also noticed is that when I run the function NSInputStream, [NSInputStream read: maxLength:], the number of bytes returned is always 158 or less. The app and hardware don’t crash, but the Bluetooth just unpairs. The device is still sending data to the RN42 even after the

Anybody has a clue on how to use the ExternalAccessory API on Xamarin.iOS? My Xamarin Studio version is 4.0.12(build 3), Xamarin.Android version 4.8.1, Xamarin.iOS version 6.4.5.0 and Xcode is Version 5.0 (5A1413) and I tried target both 6.1 and 7.0 iPad/iPhone. I've walked the internet and there is not much documentation. Even the MonoTouch docs have broken links. What I want is, list the connected bluetooth devices, get one of then by name and then connect to it so I can open a socket and start sending data to it. It is a device that uses Serial communication and yes, it has the Apple
