信标发送器广播一个固定的服务UUID以启用iOS的后台扫描。当iOS进入后台模式，UUID将从广播中消失，因此Android设备需要先搜索Apple设备，然后连接并发现用于读取UUID的服务。\n*/\nprotocol BLETransmitter : Sensor {\n}\n\n/**\n \n BLETransmitter的主要功能有两个：\n 1.保持iOS设备之间连接的信令特征，并使没有发送功能的Android设备（仅接收，像三星J6一样）通过将信标代码和RSSI作为数据写入该特征，来使其他Pioneer设备知道它们的存在。\n 2.发布信标标识数据的有效负载特征\n\n保持Transmitter和Receiver在iOS后台模式下工作是一项重大挑战，尤其是当两个iOS设备都处于后台模式时。iOS上的Transmitter提供一个可被写入数据而触发的通知信标特性。当特征写入时，Transmitter将在8秒后调用updateValue通知Receiver，用didUpdateValueFor唤醒Receiver。这个过程可以循环重复在Trabsmitter和Receiver之间以保持两个设备处于唤醒状态。这对于可以完全依赖scanForPeripherals进行检测的Android通信是不必要的，Android - iOS和iOS -Android 检测同样。\n \n 基于唤醒的通知方法依赖于一个开放的连接，这对于iOS来说似乎很好，但是可能会导致Android的问题。实验发现，Android设备不能接受新的连接（没有显式连接断开）并且蓝牙堆栈在大约500个打开的连接后停止工作。设备需要重新启动才能恢复。但是，如果每个连接都断开，蓝牙协议栈就可以工作无限期，但频繁的连接和断开仍然会导致相同的问题。建议是\n （1）工作完成后，请务必断开与Android的连接\n （2）尽量减少与Android的连接数\n （3）最大化连接之间的时间间隔。\n 考虑到这些，Transmitter在Android上不支持这种通知模式，而且仅仅在第一次接触时才执行连接以获取有效负载。\n \n */\nclass SpecificBLETransmitter : NSObject, BLETransmitter, CBPeripheralManagerDelegate {\n
