我正在使用我的应用程序连接 BLE 设备 并跟踪连接状态,如下所示
//Called when device is connected
- (void)centralManagerCBCentralManager *)central didConnectPeripheralCBPeripheral *)peripheral
{
[self.activePeripheral discoverServices:nil];
if (peripheral.isConnected)
{
currentStatusLbl.text = [NSString stringWithFormat"Connected"];
}
}
//Called if device disconnects
-(void)centralManagerCBCentralManager *)central didDisconnectPeripheralCBPeripheral *)peripheral errorNSError *)error
{
currentStatusLbl.text = [NSString stringWithFormat"Disconnected"];
[self.centralManager connectPeripheral:peripheral options:nil]; //Connect again
}
//Device found, request connection
- (void)centralManagerCBCentralManager *)central didDiscoverPeripheralCBPeripheral *)peripheral advertisementDataNSDictionary *)advertisementData RSSINSNumber *)RSSI
{
NSString *localName = [advertisementData objectForKey:CBAdvertisementDataLocalNameKey];
devieName.text = [localName stringByAppendingString" Found"];
if (localName && ![localName isEqual""])
{
[self.centralManager stopScan];
self.activePeripheral = peripheral;
self.activePeripheral.delegate = self;
[self.centralManager connectPeripheral:peripheral options:nil];
}
}
运行 7.1.1 的 iPhone 5 遇到的问题是标签上的状态不断在连接和断开之间切换。状态栏上的蓝牙图标确认了这一点(持续显示连接和断开状态)。我尝试打开/关闭设备(BLE 设备和手机的硬重置)。还打开/关闭蓝牙。但我仍然遇到这个问题。
我也遵循 here in this question 提供的建议但没有运气。
如果我做错了什么或者这是操作系统问题,有人可以告诉我吗?
谢谢。

写[主动外设保留];在 didDisconnectPeripheral 的 if 条件内。
希望对你有帮助
