我正在尝试连接蓝牙BTLE设备。我发现外围设备没有问题。

推荐答案

简短回答：你需要保留外围设备。

Short answer: You need to retain the peripheral.

长解释：核心蓝牙在发现时不知道您是否对此外围设备感兴趣。连接到它是不够的，你需要保留它。

Long explanation: Core Bluetooth does not know whether you are interested in this peripheral when it is discovered. Connecting to it is not enough, you need to retain it.

在你正在做的所有类中添加一个属性：

Add a property to the class where you are doing all that:

@property (strong) CBPeripheral     *connectingPeripheral;

然后在从<$ c返回之前，在发现设备时将外围设备分配给此属性$ c> didDiscoverPeripheral ：

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
  DDLogVerbose(@"Discovered peripheral: %@ advertisement %@ RSSI: %@", [peripheral description], [advertisementData description], [RSSI description]);

  [central connectPeripheral:peripheral options:nil];
  self.connectingPeripheral = peripheral;
}
