外部附件框架蓝牙对.每次计数的connectedAccessories 0 [英] External Accessory Framework bluetooth pair. connectedAccessories every time count 0

问题描述

我想尝试用蓝牙读取/写入数据

I want try read/write data with bluetooth

我尝试配对:

Mac Book<-> iPod 4

Mac Book <-> iPod 4

自定义设备<-> iPod 4

custom device <-> iPod 4

我尝试了这个Apple示例(EADemo) https://developer.apple.com/library/ios/samplecode/EADemo/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010079

I try this Apple sample (EADemo) https://developer.apple.com/library/ios/samplecode/EADemo/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010079

我在设置->蓝牙中创建了一对:

I created pair in the settings->bluetooth:

Mac Book<-> iPod 4-好的(已连接)

Mac Book <-> iPod 4 - ok (connected)

自定义设备<-> iPod 4-确定(已连接)

custom device <-> iPod 4 - ok (connected)

但是

[[EAAccessoryManager sharedAccessoryManager] connectedAccessories]

总是获得计数为0的数组.

always get array with count 0.

有什么想法吗?

谢谢.

推荐答案

EADemo正在使用外部附件框架，因此需要将协议字符串添加到项目的info.plist中.这就是苹果用来锁定与非MFi配件的连接的方式. 有关更多信息，请查看 MFi程序

The EADemo is using the External Accessory framework and therefore needs a protocol string added into the info.plist of your project. This is what apple use to lock down connections to non MFi accessories. For more info check out the MFi program
