nl::Ble::BleLayer

此类提供了一个接口，可供单个线程通过 BleLayer 平台接口函数将数据驱动到堆栈上行，或者通过与 BLEEndPoint 相关联的 WeaveConnection 对象使数据下行。

摘要

您可以通过以下两种方式将 WeaveConnection（由 WeaveMessageLayer 定义）与 BLE 连接相关联：

首先，应用可以被动接收传入的 BLE 连接，并通过相应的平台接口函数将此接收生成的特定于平台的 BLE_CONNECTION_OBJECT 移交给 BleLayer。这会使 BleLayer 将 BLE_CONNECTION_OBJECT 封装在 BLEEndPoint 中，并通知 WeaveMessageLayer 已收到新的 BLE 连接。然后，消息层将新的 BLEEndPoint 对象封装在 WeaveConnection 中，并通过消息层的 OnConnectionReceived 回调将此对象传递给应用。

其次，应用可以主动建立传出的 BLE 连接，例如通过连接到 BLE 外围设备。然后，它通过 WeaveMessageLayer 创建一个新的 WeaveConnection，为此连接分配一个身份验证类型，并通过 WeaveConnection::ConnectBle 将其绑定到用于新的 BLE 连接的 BLE_CONNECTION_OBJECT。然后，此函数会建立 WeaveConnection 的身份验证类型成员变量指定的安全会话类型。
