ios – 连接两个BLE外设的流程是什么样的？

我的蓝牙朋友,首先,如果你想发送这两个消息,没有必要断开当前的外设连接另一个.但是许多应用程序将连接设备(CBPeripheral)的数量限制为5-10,因为超过5-10个连接设备可能会自发丢失,我对它有点了解(我只使用4个设备).例如：

[[RKCentralManager sharedManager] scanForPeripheralsWithservices:nil options:@{CBCentralManagerScanOptionAllowDuplicatesKey:@NO}  onupdated:^(RKPeripheral *peripheral)
{
  //first of all u should start a scan

  [[RKCentralManager sharedManager] connectPeripheral: peripheral options:nil onFinished:^(RKPeripheral * connectedperipheral,NSError *error) 
     {
      //after u can connect to Peripheral immediately

         [connectedperipheral discoverservices:nil onFinish:^(NSError *error) 
         {
           // services - a collection of data and associated behaviors for accomplishing a function or feature of a device

              [connectedperipheral discovercharacteristics:nil forservice: [connectedperipheral.services lastObject] onFinish:^(CBservice *service,NSError *error) 
              {
                //after u should take a characteristic - Represents a service's characteristic
                CBCharacteristic * characteristic = service.characteristics[0];

                //and at last u can write value in characteristic in which you are going to write down something
                 NSData * data = [NSData  dataWithHexString: newString];
                 CBCharacteristicWriteType @R_874_4763@BCharacteristicWriteWithoutResponse;
                 [connectedperipheral writeValue:data forCharacteristic:characteristic type:type onFinish:nil];

              }];

         }];

     }];

}];

为蓝牙设备发送消息的近似方案,不是必须对@L_616_11@进行投资,它们可以在动作上分发.

您不应该担心连接和发送数据
对于多个设备,因为它适用于CBCentralManager,如果你正确使用它.

CBCentralManager对象用于管理已发现或连接的远程外围设备(由CBPeripheral对象表示),包括扫描,发现和连接到广告外围设备.

您可以立即连接某些设备并向其发送消息,一切正常.
如果您有疑问,请尽量回答.

这是一个很好的例子,你可以看到它的工作原理：https://github.com/ruiking/ble
