问题 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(

问题 I've looked at the Apple docs on this and it seems after adding the correct protocol to the Info.plist from my understanding it should launch the corresponding app? 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

问题 I'm writing an iOS application for communicating with mini mPlay Drumi MP18B (a small Bluetooth loudspeaker). As far as I know, showBluetoothAccessoryPickerWithNameFilter displays only devices with protocol strings added to Supported External Accessory Protocols key of Info.plist. So I need to add this protocol string to a list. Where can I get a protocol string for this certain device? Is there a list of device supported protocols anywhere in an internet? Most of manufactures doesn't mention

问题 The enum UIEventSubtype (iOS UIKit Framework) contains events such as play, pause, next, seek, etc. However, the iPod Access protocol contains numerous other events, such as select, up, down and back (think iPod with clickwheel). The iPod app on iOS can receive these other events and respond accordingly (move selection up/down/back in playlists), but developer apps don't have seem access to these controls. Does anyone know a way to receive these additional events in an iOS app (for jailbreak)

问题 I'm developing an external device, this device has a large amount of data to be sent via Bluetooth to the iphone / ipad, but sends a very slow speed is only about 60kbps. The device sends data to the PC speed is 256kbps, I think not because of device problems. Who knows the iOS Bluetooth maximum speed is? Information: Use external accessory framework, Bluetooth 2.0 + EDR Thanks, 回答1: I know this is a bit late, but based on all the work I've been doing, the iDevice's are generally slower than

问题 I have MFi device(RFID reader) and I'm trying to catch scanned tags in my app. So I use EAAccessorymanager to get the shared accessory and read data from it. When I open session and scan tags, stream function does not fire and I can't understand what I'm doing wrong. import Foundation import ExternalAccessory class RFID: NSObject, EAAccessoryDelegate, StreamDelegate { var _accessory: EAAccessory! var _session: EASession! var _protocolString: String? func turnOn() { let manager =

问题 I want try read/write data with bluetooth I try pairs: Mac Book <-> iPod 4 custom device <-> iPod 4 I try this Apple sample (EADemo) https://developer.apple.com/library/ios/samplecode/EADemo/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010079 I created pair in the settings->bluetooth: Mac Book <-> iPod 4 - ok (connected) custom device <-> iPod 4 - ok (connected) But [[EAAccessoryManager sharedAccessoryManager] connectedAccessories] always get array with count 0. Any ideas? Thanks. 回答1:

问题 I had asked this question earlier but was closed for unclear or insufficient details. Hopefully, I have explained it better. Here it goes. I am building an iOS application that communicates to the external accessory using a proprietary protocol (over iAP). I know that by adding a unique protocol name in the info.plist file, the application can be made to launch automatically when iOS device is connected to the external accessory (I am aware that support is needed from the external accessory

问题 I have a Bluetooth device enrolled in the MFi program. I am able to pair the device via Bluetooth in the iPhone settings, and then use Apple's EADemo example code to access the device via the ExternalAccessory framework. However, I'm wondering if it's possible to first silently pair in the background via CoreBluetooth , and then use the ExternalAcessory framework to communicate with the device? I've run some experiements and after pairing with CoreBluetooth , the ExternalAcessory framework
