步骤2043：蓝牙模块重新向安全模块发送来自上位机的数据，执行步骤2041。
步骤205：蓝牙模块向上位机发送操作结果。
可选地，步骤205中蓝牙模块向上位机发送操作结果时，还包括：
步骤L：蓝牙模块判断发送完成标志是否置位，是则完成发送，执行步骤206；否则继续判断。
可选地，上述步骤L中，蓝牙模块判断发送完成标志没有置位时，继续判断之前，还包括：蓝牙模块判断从接收到来自安全模块的操作结果到当前时间是否超过第六预设时间，是则执行步骤210；否则继续判断。
步骤206：蓝牙模块判断是否断开蓝牙连接，是则执行步骤207，否则执行步骤210；
具体地，蓝牙模块判断是否断开蓝牙连接，具体为：蓝牙模块中的蓝牙芯片判断是否监听到蓝牙断开事件，是则判定断开蓝牙连接，否则判定没有断开蓝牙连接。
更具体地，蓝牙协议栈在预设的时间内检测心跳包是否存在，如果是则蓝牙芯片监听不到蓝牙协议栈中的蓝牙断开事件，蓝牙模块判定没有断开蓝牙连接；否则蓝牙协议栈产生蓝牙断开事件，蓝牙芯片监听到蓝牙协议栈中的蓝牙断开事件，蓝牙模块判定断开蓝牙连接。
步骤207：蓝牙模块组织断开指令，唤醒安全模块，在第三预设时间之后向安全模块发送断开指令。例如，第三预设时间为10毫秒。
例如，蓝牙模块组织的断开指令为：6B08000000000103。
步骤208：蓝牙模块判断在第四预设时间之内是否接收到来自安全模块的断开指令的应答，是则执行步骤209；否则执行步骤210。

步骤209：蓝牙模块将自身的状态设置为深度省电模式。
步骤210：蓝牙模块设置自身状态为低功耗待机模式。
可选地，上述蓝牙模块将自身的状态设置为深度省电模式，具体为：蓝牙模块将自身的状态设置为深度睡眠模式。
相应地，上述步骤111之后还包括：安全模块设置自身状态为深度睡眠模式。
具体地，上述安全模块设置自身的状态为深度睡眠模式，具体为：安全模块关闭与自身连接的外围设备和自身的无关模块、保持自身的唤醒模块有电，并将安全模块的芯片主核下电；
具体地，上述蓝牙模块将自身的状态设置为深度睡眠模式，具体为：蓝牙模块关闭与自身连接的外围设备、关闭自身的无关模块、保持自身的唤醒模块有电，并将自身的芯片主核下电。
安全模块和蓝牙模块处于深度睡眠模式时，关闭与自身连接的外围设备、关闭自身的无关模块，模块中的芯片主核下电后时钟处于关闭状态，电流在纳安级别(功耗约为40nA)，与低速时钟模式相比省电效果更好；与关机模式相比模块能够迅速从深度睡眠模式中唤醒为工作模式，快速响应外围设备请求，用户体验较佳。
深度睡眠模式的蓝牙模块和安全模块只是将模块中的芯片下电，关闭功耗较大的外围设备，保持模块中的唤醒模块保持有电；被唤醒时通过唤醒模块唤醒，对模块中的芯片上电，设置时钟频率，无需对所有的设备进行初始化，唤醒速度比由关机状态转换为开机的速度快。
本实施例2中，当蓝牙模块断开蓝牙连接时，进入深度睡眠模式，与蓝牙断开连接后直接关机的方案相比，蓝牙模块接收到来自上位机的数据时由深度睡眠模式转换为工作模式要比由关机状态转换为工作模式的时间短，开机时可以提升用户体验，功耗处于纳安(nA)级别，比关机时功耗稍高。
可选地，步骤209中，蓝牙模块将自身状态设置为深度省电模式具体为：蓝牙模块执行关机操作。
本实施例2中，当蓝牙模块断开蓝牙连接时，蓝牙模块执行关机操作后蓝牙安全设备完全断电，功耗为0，可以最大程度节省电能，省电效果好，但是开机时需要对所有设备进行初始化，开机速度比由深度睡眠模式唤醒慢。蓝牙模块和安全模块可以共用一个供电模块，当蓝牙模块接收到来自安全模块的断开指令的应答时，执行关机操作，断开电源，与此同时安全模块也断电。
本实施例2中，上述蓝牙模块设置自身状态为低功耗待机模式，具体为：蓝牙模块关闭与自身连接的外围设备和自身的无关模块。进一步地，蓝牙模块设置自身状态为低功耗待机模式时，还包括：蓝牙模块将自身的时钟设置为低速时钟模式，并将自身的芯片设置为睡眠模式。例如，低速时钟模式的时钟频率为0.7MHz。
需要说明的是，本实施例2中蓝牙模块中的无关模块包括但不限于通信模块；无关模块中的通信模块可以但不限于UART(Universal Asynchronous Receiver/Transmitter，通用异步收发传输器)模块/SPI(Serial Peripheral Interface，串行外设接口)模块/I2C(Inter－Integrated Circuit，内部集成电路)模块。
本实施例2中，上述安全模块设置自身的状态为低功耗待机模式，具体为：安全模块将自身的时钟设置为低速时钟模式，关闭自身的无关模块以及与安全模块连接的外围设备，将自身的芯片设置为睡眠模式。
例如，安全模块将自身的时钟频率由2.5MHz设置为0.07MHz；
具体地，安全模块关闭与其连接的外围设备，具体为：关闭与其连接的功耗较大的外围设备。例如，关闭与其连接的显示模块。
具体地，安全模块中的无关模块包括通信模块、算法模块和存储模块。例如，算法模块可以包括但不限于SM4算法模块/SM1算法模块/Hash 算法模块/Sha2算法模块；
安全模块的通信模块可以但不限于UART(Universal Asynchronous Receiver/Transmitter，通用异步收发传输器)模块/SPI(Serial Peripheral Interface，串行外设接口)模块/I2C(Inter－Integrated Circuit，内部集成电路)模块/USB(Universal Serial Bus，通用串行总线)模块。
本实施例2中，上述安全模块设置自身状态为工作模式，具体为：安全模块将自身的时钟切换为高速时钟模式。
例如，当安全模块处于低功耗待机模式，等待被唤醒时，时钟频率为0.07MHz，安全模块将时钟切换为高速时钟模式具体为：安全模块将时钟频率由0.07MHz切换为2.5MHz。
本发明中，蓝牙模块和安全模块设置自身状态为低功耗待机模式时将自身的芯片设置为睡眠模式，同时关闭时钟的，可以进一步降低功耗。如果只关闭时钟，不将芯片设置为睡眠模式，芯片会继续执行工作程序，当将芯片设置为睡眠模式之后，芯片停止执行工作程序。
进一步地，安全模块设置自身状态为工作模式时，还具体包括：安全模块开启自身的无关模块。例如，安全模块开启通信模块和算法模块。本发明中，安全模块中的算法模块和通信模块可以内置在安全模块的芯片中也可以与安全模块中的芯片连接。更进一步地，安全模块设置自身状态为工作模式时，还具体包括：安全模块开启与自身连接的外围设备，例如，开启与自身连接的显示模块。
本实施例2中，上述蓝牙模块设置自身的状态为工作模式，具体为：蓝牙模块开启自身的通信模块。
进一步，蓝牙模块设置自身的状态为工作模式时，还包括：蓝牙模块将自身时钟切换为高速时钟模式。例如，蓝 牙模块将时钟频率由0.07MHz切换成2.5MHz。更进一步地，蓝牙模块设置自身的状态为工作模式时，还包括：蓝牙模块开启与自身连接的外围设备。
本实施例2中，上述蓝牙模块唤醒安全模块具体为：蓝牙模块拉低与安全模块连接的第一控制管脚的电平。例如，蓝牙模块与安全模块连接的第一控制管脚为combus控制线。可选地，本实施例2中，还包括：蓝牙模块拉低与安全模块连接的第一控制管脚的电平之后的预设时间内，蓝牙模块将第一控制管脚的电平拉高。例如，蓝牙模块拉低与安全模块连接的第一控制管脚的电平之后的10毫秒之内，蓝牙模块将第一控制管脚的电平拉高。
本实施例2中，蓝牙安全设备的外围设备包括显示模块，但不限于显示模块，上述显示模块与安全模块连接，但不限于此连接方式。例如，显示模块可以与安全模块和/或蓝牙模块连接。
本实施例2中，安全模块处于关机模式时，安全模块下电，被蓝牙模块唤醒时，首先要上电(具体地，安全模块上电具体为蓝牙模块通过LDO或者MOS管给安全模块供电)，将时钟设置为高速时钟模式，并对硬件进行初始化；
安全模块处于深度睡眠模式时，安全模块中的安全芯片的主核下电，与安全模块连接的外围设备关闭，同时安全模块连接的算法模块、无关模块关闭，只有安全模块中的唤醒模块有电，被蓝牙模块唤醒后，安全模块通过唤醒模块唤醒，对安全模块的芯片主核上电，设置时钟为高速时钟模式；
安全模块处于低功耗待机模块时，安全模块只关闭功耗较大的外围设备，安全模块的芯片有电，时钟为低速时钟模式，并且安全模块的芯片设置为睡眠模式，接收到上位机的数据时，将时钟设置为高速时钟模式。
本实施例2中，蓝牙模块处于关机模式时，蓝牙模块下电，接收到开机事件时，蓝牙芯片上电(具体地，蓝牙模块接收到开机事件具体为：用户按下蓝牙安全设备的开机按键后，触发开机事件)，将时钟设置为高速时钟模式，对硬件进行初始化(硬件包括电容等器件)；
蓝牙模块处于深度睡眠模式时，蓝牙模块中的芯片主核下电，与蓝牙模块连接的外围设备关闭，同时蓝牙模块中的无关模块(如通讯模块SPI/UART/I2C)关闭，只有蓝牙模块中的唤醒模块有电，接收到开机事件时，通过唤醒模块唤醒，对蓝牙芯片的主核上电，设置时钟为高速时钟模式；
蓝牙模块处于低功耗待机模块时，蓝牙模块只关闭功耗较大的外围设备，蓝牙模块的芯片有电，时钟为低速时钟模式，并且蓝牙模块的芯片处于睡眠模式，接收到上位机的数据时，将时钟设置为高速时钟模式。
本发明中，安全模块和蓝牙模块在完成相应操作时直接进入低功耗待机模式，与现有技术中蓝牙安全设备被上位机唤醒必须在预设时间之后才进入低功耗待机模式的方案相比，省电效果更佳；另外本发明中，安全模块和蓝牙模块处于低功耗待机模式时，将各自时钟切换为低速时钟模式，同时关闭与自身连接的外围设备和自身的无关模块，与现有技术中只关闭外围设备的低功耗待机模式相比功耗更低，省电效果更好。当蓝牙模块判断断开蓝牙连接时，安全模块和蓝牙模块进入深度省电模式，如此比普通的低功耗待机模式省电效果更好。

本发明与现有技术相比的有益效果是：蓝牙安全设备中，安全模块判断没有接收到数据时以及将操作结果返回蓝牙模块之后都立即将自身状态设置为低功耗待机模式，与现有技术中蓝牙安全设备的省电方式相比，省电效果好，进一步提高蓝牙安全设备的待机时长。
安全模块处理相应操作之后随时进入低功耗待机模式，同时蓝牙模块将来自安全模块的操作结果返回上位机之后也立即进入低功耗待机模式，与现有技术蓝牙安全设备在预设时间之后才进入低功耗待机模式相比，可以进一步提高蓝牙安全设备的待机时长。
另外，本发明中，安全模块和蓝牙模块处于低功耗待机模式时，将各自时钟切换为低速时钟模式，同时关闭外围设备，与现有技术只关闭外围设备的低功耗待机模式相比功耗更低，省电效果更好。
以上，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，本领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所附权利要求书的保护范围为准。
