Ios6 连接后立即断开iOS 6外围设备
好的,我正在使用核心蓝牙将我的I-Pad连接到另一个BLE传感器。 我很容易扫描并检测它,但当我想建立连接时,“did connect peripheral”方法只在30秒内调用,就好像我调用了断开连接一样。。。 即使我在所需的后台模式下选择或取消选择“应用程序使用CoreBooth进行通信”,该结果仍然保持不变Ios6 连接后立即断开iOS 6外围设备,ios6,connection,core-bluetooth,cbperipheral,Ios6,Connection,Core Bluetooth,Cbperipheral,好的,我正在使用核心蓝牙将我的I-Pad连接到另一个BLE传感器。 我很容易扫描并检测它,但当我想建立连接时,“did connect peripheral”方法只在30秒内调用,就好像我调用了断开连接一样。。。 即使我在所需的后台模式下选择或取消选择“应用程序使用CoreBooth进行通信”,该结果仍然保持不变 - (id) init { self = [super init]; if (self) { pendingInit = YES;

如何避免连接后立即断开外围设备?
它让我发疯 您必须在DidDiscoveryPeripal上执行[peripheral retain],或将其放入retain属性。
它在通过BLE框架连接后立即释放。我有一个错误:尝试连接到外围传感器已断开连接:指定的设备已与我们断开连接。您是否使用
CBPeripheral
对象,连接时:yourpheral=peripal
中的didConnect
委托并设置其委托:yourpheral setDelegate:self
(self或另一个类)?您连接的实际BLE设备是什么?
