具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本申请进一步详细说明。
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的 元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能解释为对本申请的限制。
本技术领域技术人员可以理解，除非特意声明，这里使用的单数形式“一”、“一个”、“所述”和“该”也可包括复数形式。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
需要说明的是，本申请实施例中所有使用“第一”和“第二”的表述均是为了区分两个相同名称非相同的实体或者非相同的参量，可见“第一”“第二”仅为了表述的方便，不应理解为对本申请实施例的限定，后续实施例对此不再一一说明。
如图1所示，物联网终端支持GPRS+蓝牙，中间设备支持4G+蓝牙，当中间设备的蓝牙打开时，物联网设备会优先选择通过蓝牙(Bluetooth)连接中间设备，并通过中间设备连接物联网平台，以节省物联网终端的流量或功耗。
