具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
本公开一示例性实施例提供了一种唤醒MCU的方法，本方法实施例应用于具有Wi-Fi模块的第一智能设备中，参见图1，方法流程包括：
在步骤101中，当无线保真Wi-Fi芯片处于低功耗模式时，接收第二智能设备发送的无线报文，无线报文属于低功耗模式下专用的报文；
在步骤102中，检测无线报文是否属于指定的唤醒报文；
在步骤103中，如果检测出无线报文属于指定的唤醒报文，通过Wi-Fi芯片与微控制单元MCU芯片之间连接的唤醒引脚，向MCU芯片发送中断唤醒信号唤醒MCU芯片；
其中，MCU芯片与Wi-Fi芯片属于同一个Wi-Fi模块。
其中，本公开实施例中的第一智能设备和第二智能设备可以为手机、平板电脑等终端类设备；也可以为智能穿戴设备、智能家用电器等设备，在此并不限定。
在本公开实施例中第一智能设备当前状态下处于Wi-Fi模块中的MCU芯片进入了 深度睡眠状态，并且Wi-Fi模块中的Wi-Fi芯片也进入了低功耗模式下。
其中，Wi-Fi芯片在低功耗模式下只能接收低速率、小数据量的无线报文，即低功耗模式下专用的无线报文。
由于Wi-Fi模块功耗较大，为了降低智能设备功耗有效利用能源，智能设备会在Wi-Fi模块没有数据收发任务时控制Wi-Fi模块中的MCU芯片进入深度睡眠状态，并在有业务逻辑需要运行时通过中断事件来唤醒MCU芯片进入工作状态。如果智能设备控制MCU芯片进入深度睡眠状态，则其他智能设备无法与本端进行数据的收发，必须等待MCU芯片被唤醒后向其他智能设备广播自身已被唤醒的通知之后，才可与其他智能设备进行数据的收发操作。
本公开实施例可以通过其他智能设备在有数据收发的需求时，通过远程发送唤醒报文的方式告知本端的Wi-Fi芯片，触发Wi-Fi芯片通过与MCU芯片之间连接的唤醒引脚来唤醒本端的MCU芯片，提高了智能设备之间数据传输的效率。
本公开一示例性实施例提供了一种唤醒MCU的方法，本方法实施例应用于智能设备中，参见图2。MCU芯片与Wi-Fi芯片属于同一个Wi-Fi模块。
其中，方法流程包括：
在步骤201中，当Wi-Fi芯片处于低功耗模式时，Wi-Fi芯片接收第二智能设备发送的无线报文，无线报文属于低功耗模式下专用的报文。
在步骤202中，检测无线报文是否属于指定的唤醒报文。
在步骤203中，如果检测出无线报文属于指定的唤醒报文，通过Wi-Fi芯片与MCU芯片之间连接的唤醒引脚，向MCU芯片发送中断唤醒信号唤醒MCU芯片。
其中，步骤201-步骤203为唤醒Wi-Fi模块中的MCU芯片的流程，在唤醒MCU芯片之后进入与第二智能设备通信的流程。
在步骤204中，MCU芯片控制Wi-Fi芯片由低功耗模式进入正常工作模式。
在步骤205中，MCU芯片控制Wi-Fi芯片广播通知报文。
在步骤206中，Wi-Fi芯片接收第二智能设备根据通知报文发送的数据。
本公开实施例可以通过其他智能设备在有数据收发的需求时，通过远程发送唤醒报文的方式告知本端的Wi-Fi芯片，触发Wi-Fi芯片通过与MCU芯片之间连接的唤醒引脚来唤醒本端的MCU芯片，并在唤醒后与其他智能设备进行通信。提高了智能设备之间数据传输的效率。
本公开一示例性实施例提供了一种唤醒MCU的方法，本方法实施例应用于智能设 备中，参见图3，方法流程包括：
在步骤301中，当检测到触发了向第一智能设备发送数据的事件时，第二智能设备生成用于唤醒第一智能设备Wi-Fi模块中的MCU芯片的唤醒报文；唤醒报文属于第一智能设备Wi-Fi模块中的Wi-Fi芯片处于低功耗模式下专用的报文；
在步骤302中，将唤醒报文发送给第一智能设备，以唤醒第一智能设备Wi-Fi模块中的MCU芯片。
其中，本公开实施例中的第一智能设备和第二智能设备可以为手机、平板电脑等终端类设备；也可以为智能穿戴设备、智能家用电器等设备，在此并不限定。
其中，在本公开实施例中，第二智能设备可以在每次触发了向第一智能设备发送数据的事件后，无论第一智能设备是否处于深度睡眠状态，都会向第一智能设备发送唤醒报文，以提示第一智能设备准备发送数据；
另一种情况下，第一智能设备会定期向第三方服务器发送自身的状态，例如：通过发送心跳报文方式告知第三方服务器第一智能设备的Wi-Fi模块处于工作状态。如果第三方服务器未按时收到第一智能设备发送的心跳报文，则可以确定第一智能设备中的Wi-Fi模块处于休眠状态，即Wi-Fi芯片处于低功耗模式，MCU芯片处于深度睡眠状态。因此，第二智能设备可以在触发了向第一智能设备发送数据的事件时，向第三方服务器获取第一智能设备的状态，并确定第一智能设备的Wi-Fi模块处于休眠状态时，向第一智能设备发送唤醒报文。
本公开实施例可以通过其他智能设备在有数据收发的需求时，通过远程发送唤醒报文的方式告知本端的Wi-Fi芯片，触发Wi-Fi芯片通过与MCU芯片之间连接的唤醒引脚来唤醒本端的MCU芯片，提高了智能设备之间数据传输的效率。
本公开一示例性实施例提供了一种唤醒MCU的方法，本方法实施例应用于智能设备中，参见图4。
其中，该方法流程包括：
在步骤401中，当检测到触发了向第一智能设备发送数据的事件时，生成用于唤醒第一智能设备Wi-Fi模块中的MCU芯片的唤醒报文；唤醒报文属于第一智能设备的Wi-Fi模块中的Wi-Fi芯片处于低功耗模式下专用的报文。
在步骤402中，将唤醒报文发送给第一智能设备，以唤醒第一智能设备Wi-Fi模块中的MCU芯片。
其中，步骤401至步骤402为需要与第一智能设备进行通信时，唤醒第一智能设备Wi-Fi模块中的MCU芯片的流程；从步骤403开始进入唤醒了第一智能设备Wi-Fi模块 中的MCU芯片后的通信流程。
在步骤403中，接收第一智能设备Wi-Fi模块中的MCU唤醒之后发送的通知报文。
在步骤404中，根据通知报文，向第一智能设备发送数据。
本公开实施例可以通过其他智能设备在有数据收发的需求时，通过远程发送唤醒报文的方式告知Wi-Fi芯片，触发Wi-Fi芯片通过与MCU芯片之间连接的唤醒引脚来唤醒本端的MCU芯片，并在唤醒后与其他智能设备进行通信。提高了智能设备之间数据传输的效率。
本公开一示例性实施例提供了一种唤醒MCU的方法，参见图5。
本公开实施例为结合第一智能设备和第二智能设备两方的操作流程对唤醒第一智能设备Wi-Fi模块中的MCU芯片的流程进行描述，以及在唤醒后进行通信的流程进行描述。
其中，该方法流程包括：
在步骤501中，当检测到触发了向第一智能设备发送数据的事件时，第二智能设备生成用于唤醒第一智能设备Wi-Fi模块中的MCU芯片的唤醒报文；唤醒报文属于第一智能设备Wi-Fi模块中的Wi-Fi芯片处于低功耗模式下专用的报文。
其中，第一智能设备中预置有Wi-Fi芯片处于低功耗模式下专用的报文的协议，根据该协议以及生成唤醒报文的规则，生成唤醒报文。
在步骤502中，将唤醒报文发送给第一智能设备，以唤醒第一智能设备Wi-Fi模块中的MCU芯片。
可选的，由于第一智能设备的Wi-Fi芯片处于低功耗模式，有可能接收低功耗模式下专用报文的接口不可靠，因此第二智能设备发送的唤醒报文可以发送多次。
相应的，在第一智能设备侧可以允许第一个唤醒报文未被响应。
在步骤503中，当Wi-Fi芯片处于低功耗模式时，第一智能设备Wi-Fi模块中的Wi-Fi芯片接收第二智能设备发送的无线报文；无线报文属于低功耗模式下专用的报文。
其中，本步骤为第一智能设备Wi-Fi模块中的Wi-Fi芯片。
在步骤504中，检测无线报文是否属于指定的唤醒报文。
其中，第一智能设备中预先设置有唤醒报文的生成规则，根据该生成规则可以确定接收到的无线报文是否属于唤醒报文。其中，可以通过在无线报文中的各字段中于生成规则进行匹配的方式来确定是否属于唤醒报文。
在步骤505中，如果检测出无线报文属于指定的唤醒报文时，则通过Wi-Fi芯片与MCU芯片之间连接的唤醒引脚，向本端MCU芯片发送中断唤醒信号唤醒MCU芯片。
其中，MCU芯片与Wi-Fi芯片属于同一个Wi-Fi模块。
Wi-Fi模块中的Wi-Fi芯片与MCU芯片之间连接有唤醒引脚，通过该唤醒引脚可以使得Wi-Fi芯片在接收到唤醒报文时，触发Wi-Fi芯片通过唤醒引脚发送脉冲信号，即向MCU芯片发送中断唤醒信号。
在本公开实施例中，MCU芯片通过来自远端智能设备发送的唤醒报文，触发外部的中断唤醒信号来进行唤醒，来实现远程唤醒MCU芯片的方式。
在步骤506中，第一智能设备Wi-Fi模块中的MCU芯片控制Wi-Fi芯片由低功耗模式进入正常工作模式。
在步骤507中，第一智能设备Wi-Fi模块中的MCU芯片控制Wi-Fi芯片广播通知报文。
其中，通知报文可以以广播的方式进行发送，以让广播范围内的第二智能设备以及其他智能设备获知第一智能设备的Wi-Fi模块已经进入工作状态，可以进行数据的收发。
在步骤508中，第二智能设备接收第一智能设备Wi-Fi模块中的MCU唤醒之后发送的通知报文。
此时，第二智能设备确定第一智能设备中WI-FI模块已经进入工作状态，即MCU芯片已经被唤醒，WI-FI芯片已经进入正常工作模式，可以确定第一智能设备可以进行收发数据。
在步骤509中，第二智能设备根据通知报文，向第一智能设备发送数据。
在步骤510中，第一智能设备接收第二智能设备根据通知报文发送的数据。
至此，通过第二智能设备远程唤醒第一智能设备中的MCU芯片，并唤醒MCU芯片之后进行传输数据的步骤结束。
本公开实施例可以通过其他智能设备在有数据收发的需求时，通过远程发送唤醒报文的方式告知本端的Wi-Fi芯片，触发Wi-Fi芯片通过与MCU芯片之间连接的唤醒引脚来唤醒本端的MCU芯片，并在唤醒后与其他智能设备进行通信。提高了智能设备之间数据传输的效率。
