Description

一种设备连接方法、装置和系统
本申请要求2015年06月16日递交的申请号为201510334071.X、发明名称为“一种设备连接方法、装置和系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及计算机技术领域，特别是涉及一种设备连接方法、装置和系统。
背景技术
随着技术的发展，人们使用移动终端的频率越来越高，在人们使用移动终端的过程中，使用该移动终端与其他设备进行交互，以传输或者获取信息的频率也越来越高。比如某个用户将移动终端通过接入wifi(wireless fidelity，无线保真)设备以访问互联网；又比如某个用户将移动终端通过蓝牙连接接入另外一个用户的移动终端或者其他设备，以传输或者接收数据，比如传输图片、视频、文档等等；又比如，某个用户将移动终端通过OTG(On-The-Go，其是在没有网络节点的情况下，实现设备间的数据传送的技术)连接到另外一个用户的设备，以传输或者接收数据。
而用户的移动终端通过类似前述的各种方式连接到某个设备，存在如下几种连接方式：
其一，由用户在移动终端找到设备标识，输入连接密码进行连接，一般包括如下几个步骤：
(1)用户通过某种渠道获取设备标识及连接密码；
以wifi路由器为例，如果用户A想连接到该wifi路由器，可以从该wifi路由器的设置者处问询wifi路由器的标识和连接密码。其问询的方式可以由多种方式。比如wifi路由器的标识为ABC，密码为123456。
(2)用户在其移动终端上打开相应连接界面，查找相应标识所对应的设备；
比如用户打开手机的wifi的连接界面，在该连接界面中众多wifi路由器标识中查找ABC对应的wifi路由器标识。
(3)用户选择相应的设备，进入相应密码输入界面之后，输入连接密码以进行连接。
比如对前述ABC的wifi路由器标识，用户点击该标识，进入登录界面，然后输入 连接密码，点击连接。如果连接密码正确，则连接到ABC的wifi路由器；如果连接密码不正确，则连接失败。
其二，用户利用移动终端扫描针对设备的二维码与该设备进行连接。
其三，在一些特制移动终端中，加入NFC(Near Field Communication，近距离无线通信)模块，通过NFC模块与设备进行连接。
但是，对于上述第一种连接方式，容易发生由于人为的密码输入错误而导致连接失败；用户的操作繁琐，并且整个过程耗时长；还有由于设备标识和密码是对外界暴露的，在用户获取设备标识和密码时容易被他人盗用。
对于上述第二种连接方式，需要移动终端具备摄像头，并且被连接设备具有显示屏，对摄像头的精度、自动对焦等还有一定要求，用户操作也比较繁琐。
对于上述第三种连接方式，由于很多移动终端都不包含NFC模块，其应用范围狭窄，无法满足需求。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的核心思想之一在于，对于用户使用具备音频接口的第一设备，当其想要将第一设备与目标设备进行无线连接时，通过第一设备的音频接口连接到目标设备或者中继设备中，通过音频信号指示目标设备或者中继设备去获取目标设备的无线连接权限信息，然后第一设备即可自动根据该无线连接权限信息与目标设备进行无线连接。节省用户的操作步骤，提高连接速度，提高目标设备无线连接权限信息的安全性。
需要说明的是，在本申请实施例中，上述第一设备包括移动终端，上述移动终端是指可以在移动中使用的计算机设备，广义的讲包括手机、笔记本、平板电脑、POS(point of sale，销售终端)机、车载电脑等。
上述目标设备包括具备无线接入功能的设备，比如提供wifi的无线路由器，可以设置为wifi热点的移动终端，可以提供蓝牙连接、红外线连接接入功能的移动终端等。
上述中继设备为第一设备和目标设备之间的设备，可以独立于目标设备，由中继设备获取目标设备的无线连接权限信息；上述中继设备与第一设备直接进行音频通信，将无线连接权限信息返回第一设备。
参照图1，其示出了本申请的一种设备连接方法的步骤流程图。
图1所示实施例从发起连接的第一设备一侧进行描述，具体可以包括如下步骤：
步骤110，检测第一设备的音频接口是否被插入；如果检测到第一设备的音频接口被插入，则进入步骤120；如果未检测到第一设备的音频接口被插入，则不进行后续执行过程。
可以理解，在本申请实施例中，上述第一设备具备音频接口，对于音频接口，常见的包括四个引脚：GND(地底线)、L(左声道)、R(右声道)和MIC(麦克风)。
可以理解，本申请实施例中对音频接口的孔径不进行任何限制，音频接口为任意孔径皆可应用本申请实施例的技术方案。比如3.5毫米孔径的音频接口，2.5毫米孔径的音频接口，或者其他孔径的音频接口，本申请实施例不做限制。
在实际应用中，检测音频接口是否被插入是通过检测GND和MIC之间的阻抗是否为指定值，当GND和MIC之间的阻抗达到指定值，则确认音频接口被插入。上述指定值比如现在通用手机的阻抗设置的4.99K，当然也可根据终端的需要设置其他值。
在实际应用中，可以调用相应操作系统的API去检测音频接口是否被插入。具体调用的API随操作系统的不同而有不同，本申请不对其加以限制。比如对于Android系统，可以调用HeadsetObserver检测音频接口是否被插入。
在本申请实施例中，检测的是第一设备的音频接口是否被音频线的音频接头插入。然后第一设备可以通过音频线连接到目标设备获取无线连接权限信息，或者第一设备可以通过音频线连接到中继设备，由中继设备去获取目标设备的连接权限。
其中，在本申请实施例中，本申请的执行逻辑可通过多种形式预置在第一设备中。比如对于手机、平板等移动终端，可通过APP应用的形式安装到移动终端的系统中。也可以将本申请的执行逻辑在第一设备上市之前直接写入第一设备的操作系统中。那么用户在第一设备中启动本申请的执行逻辑，比如打开相应APP应用之后，即可检测第一设备的音频接口是否被插入。
那么，当用户将音频插头插入第一设备的音频接口后，则检测第一设备的音频接口被插入，然后即可进入步骤120。
步骤120，通过所述音频接口发送第一音频信号；所述第一音频信号用于指示获取目标设备的无线连接权限信息；
在检测到音频接口被插入之后，则可以生成用于指示获取目标设备的无线连接权限信息的第一音频信号，然后将该第一音频信号通过音频接口发出。然后该第一音频信号 可通过音频线传输到前述目标设备或者前述中继设备。
可以理解，上述目标设备或者说中继设备预置了相应的用于处理音频信号的模块，对接收到的各种音频信号进行解析，执行相应动作以获取目标设备的无线连接权限信息，然后返回包括无线连接权限信息的第二音频信号。
可以理解，上述目标设备的无线连接权限信息包括目标设备的设备标识和连接密码。比如对于无线路由器，上述无线连接权限信息包括ssid(Service Set Identifier，服务集标识)和wifi的连接密码。比如对于设置为无线热点的手机，上述无线连接权限信息包括手机的设备标识和无线热点的连接密码。比如对于手机的蓝牙连接，无线连接权限信息包括手机设备标识以及蓝牙连接的连接密码。
当然，上述无线连接权限信息也可采用其他信息，只要是第一设备无线连接目标设备时所需要的信息即可，本申请不对其加以限制。
在本申请的一个实施例中，步骤120可以包括如下子步骤：
子步骤S121，生成权限获取指令；所述权限获取指令用于获取目标设备的无线连接权限信息；
在确定音频接口被插入之后，本申请即可生成权限获取指令，该权限获取指令用于获取目标设备的无线连接权限信息。
本申请可以采用各种协议构建权限获取指令，在第一设备和目标设备，或者第一设备和中继设备之间采用一套协议。
在具体实现中，以简单文本协议为例，本申请可以在确定音频接口被插入后，根据简单文本协议构造权限获取指令。其简单文本协议构造的指令格式如“数据内容为字符串明文“\r\n”，其中以\r\n作为命令或音频响应信号的结束。比如获取路由器的ssid和连接密码，构造的权限获取指令为“getssid:+Equipment info+“\r\n”。
当然，在此仅以简单文本协议为例，本申请还可采用其他协议，本申请不对其加以限制。
子步骤S122，将所述权限获取指令调制为第一音频信号；
然后对于前述生成的权限获取指令，即可将其调制为第一音频信号。如此，第一音频信号也可以理解为用于指示获取目标设备的无线连接权限信息。
由于音频接口和音频线传输的是音频信号，其是波形的信号。而在权限获取指令本身是数字信号，那么需要将数字信号调制为音频信号，才能通过音频线传输给目标设备或者中继设备。
在具体实现中，，将数字信号调制为音频信号，将音频信号解调为数字信号，可以采用2FSK(2binary frequency shift keying，二进制频移键控)的方式进行调制解调。2FSK就是用二进制里的0、1来控制载波的频率，从而达到通信的目的。例如：用1ms(微米)长、1KHz(千赫兹)的正弦信号来代表二进制里的1；用1ms长、2KHz的正弦来代表二进制里的0；那一连串的1KHz、2KHz的信号解调出来就是一连串的0和1。那么在本申请中可以根据需要设置x微米长，y千赫兹的正弦信号代表2进制里的1；设置m微米长，n千赫兹的正弦信号代表2进制里的0。
当然，具体的调制解调方式还可以采用其他方式，本申请不对其加以限制。
那么在步骤S122中，本申请将权限获取指令采用2FSK的方式调制为第一音频信号。
如前述简单文本协议的权限获取指令为“getssid:+Equipment info+“\r\n”，由于简单文本协议采用的字符为ASCII表(American Standard Code for Information Interchange，美国标准信息交换代码)中的字符，而ASCII表的字符在底层都有一个一一对应的二进制代码，那么对于“getssid:+Equipment info+“\r\n”，其实质对应一连串的二进制代码，将上述一连串的二进制代码通过2FSK可以调制为波形信号，即第一音频信号。
子步骤S123，将所述第一音频信号由音频接口发出。
然后即可通过音频接口传输到音频线，再通过音频线传输到目标设备或者中继设备。
在本申请的一个实施例中，子步骤S123可以包括如下子步骤：
子步骤S124，调用音频输出API，通过音频接口的左声道引脚和/或右声道引脚，将上述第一音频信号发出。
在实际应用中，可以调用相应操作系统的API(Application Program Interface，应用程序编程接口)去检测音频接口是否被插入。具体调用的API随操作系统的不同而有不同，本申请不对其加以限制。以Android系统为例，可以调用AudioTrack将上述第一音频信号从音频接口输出。然后第一音频信号沿着音频线就输送到目标设备或者中继设备。当然不同的操作系统，其调用的音频输出API也可能不同，本申请不对其加以限制。
对于第一音频信号的输出，可以只是以左声道引脚传输，也可以只使用右声道引脚传输，也可以两者结合进行传输，本申请不对其加以限制。
可以理解，应用本实施例，可以预先在上述目标设备或者说中继设备设置相应的处理音频信号的模块，设置相同的通信协议，以及在相应的通信协议下，对不同指令预置相应的处理逻辑。
比如都预置了2FSK和简单文本协议的处理音频信号的模块，在目标设备侧预置了 对指令权限获取指令的处理逻辑，那么对于前述转换后的对应“getssid:+Equipment info+“\r\n”的第一音频信号。先将第一音频信号采用2FSK解调为一系列二进制代码，然后将该一系列二进制代码从头部与ASCII表进行匹配，转换即得到“getssid:+Equipment info+“\r\n”，目标设备或中继设备识别该指令为获取目标设备的ssid和连接密码，则执行该指令，获取目标设备的ssid和连接密码，再将ssid和连接密码调制为第二音频信号通过音频线返回第一设备。
在本申请实施例中，目标设备或者中继设备在获取到无线连接权限信息之后，会基于该无线连接权限信息生成返回指令，然后将该返回指令调制为第二音频信号返回第一设备。
如前述简单文本协议和2FSK机制下路由器的例子，可将获取到的ssid和连接密码，构造为返回指令“ssid+password“\r\n”的形式，然后再对“ssid+password“\r\n”以前述相同的机制采用2FSK调制为第二音频信号，再将第二音频信号返回第一设备。
在本申请实施例中，目标设备或中继设备返回的第二音频信号可通过麦克风引脚返回的，第二音频信号然后通过音频线中的麦克风线返回第一设备。
步骤130，通过所述音频接口接收第二音频信号；所述第二音频信号包括目标设备的无线连接权限信息；
第一设备则通过音频接口接收第二音频信号，该第二音频信号则包括了目标设备的无线连接权限信息。
在本申请的一个实施例中，步骤130可以包括如下子步骤：
子步骤S131，调用音频输入API，从音频接口的麦克风引脚中接收所述第二音频信号。
在实际应用中，可以调用相应操作系统的API从音频接口的麦克风引脚中接收上述第二音频信号。具体调用的API随操作系统的不同而有不同，本申请不对其加以限制。以Android系统为例，可以调用AudioRecordk从音频接口的麦克风引脚中接收上述第二音频信号。
步骤140，根据所述第二音频信号中的无线连接权限信息，将所述第一设备与目标设备进行无线连接。
由于第二音频信号中包括了目标设备的连接权限信息，本步骤则可从第二音频信号中提取无线连接权限信息，然后在根据该无线连接权限信息，将苏颂第一设备与目标设备进行无线连接。
在本申请的一个实施例中，步骤140可以包括如下子步骤：
子步骤S141，所述第一设备通过音频接口接收到所述第二音频信号之后，解调所述第二音频信号；
对于目标设备或者中继设备返回的第二音频信号，本申请则可采用相应的解调机制对第二音频信号进行解调。
如前述的包括回指令“ssid+password“\r\n”的第二音频信号，采用2FSK对第二音频信号进行解调，得到一系列二进制码，再将该一系列二进制码从头部与ASCII表进行匹配，转换即得到“ssid+password“\r\n”。
子步骤S142，从解调后的结果中，提取目标设备的无线连接权限信息；
如前述的解调后的结果“ssid+password“\r\n”中，可以提取无线连接权限信息ssid和password。
子步骤S143，基于所述无线连接权限信息，将所述第一设备与目标设备进行无线连接。
以前述无线连接权限信息ssid和password为例，得到该无线连接权限信息之后，即可将第一设备连入前述无线路由器的wifi中。
在本申请的一个实施例中，子步骤S143可以包括如下子步骤：
子步骤S144，用无线连接API，根据所述无线连接权限信息将第一设备与目标设备进行无线连接；
在实际应用中，无论是wifi、蓝牙连接还是红外线连接，均需要目标设备的设备标识和连接密码之后，第一设备的相应wifi模块、蓝牙连接模块或者红外线连接模块才能向目标设备发送正确的连接请求，使第一设备和目标设备可以成功连接。
对于前述无线路由器的连接，第一设备以Android系统为例，在第一设备中可调用WifiConfiguration，根据上述无线连接权限信息将第一设备与目标设备进行无线连接。
在本申请的一个实施例中，子步骤S144可以包括如下子步骤：
子步骤S144，调用无线连接API中的无线配置API，根据所述无线连接权限信息进行无线连接配置；
第一设备以Android系统为例，在连接前述无线路由器的wifi时，其调用WifiManager在第一设备中进行wifi热点配置。
上述WifiManager首先获取WifiManager对象，然后在该WifiManager对象中进行如下配置：
(1)配置wifi热点的类，如WifiConfiguration apConfig＝new WifiConfiguration()；
(2)配置wifi热点的名称，如apConfig.SSID＝"YRCCONNECTION"；
(3)配置热点的密码，如apConfig.preSharedKey＝"password"；
(4)通过反射调用以设置wifi热点，并确定wifi加密类型，如Method method＝wifiManager.getClass().getMethod(
"setWifiApEnabled",WifiConfiguration.class,Boolean.TYPE)；
(5)返回热点打开状态，如return(Boolean)method.invoke(wifiManager,apConfig,true)；如此，wifi热点在第一设备中配置完毕。
子步骤S145，调用无线连接中的连接API，根据所述无线连接配置，将第一设备连接到目标设。
在前述wifi热点在第一设备中配置完毕，则可将第一设备连接到目标设备的wifi中。
以前述第一设备以Android系统为例，将第一设备连接到目标设备的wifi中时，可调用WifiConfiguration进行连接。
在进行wifi连接时，WifiConfiguration获取WifiManager对象后，以WifiManager对象为基准创建WifiConfiguration对象。然后在WifiConfiguration对象中根据wifi加密类型选择相应类型的连接方式，以将第一设备连接到目标设备的wifi中。
在WifiConfiguration对象中根据wifi加密类型选择相应类型的连接方式比如：
(1)Type＝1，表示wifi没有设置密码，则在WifiConfiguration对象中按序进行如下操作：
将KeyMgmt字段设置为NONE；
将wepTxKeyIndex字段设置为0；
可将上述设置添加到wifi列表；
执行WifiConfiguration中的函数wifiManager.enableNetwork(wcgID,true)即可连接到目标设备的wifi。
(2)Type＝2，表示wifi为WEP加密类型，则在WifiConfiguration对象中按序进行如下操作：
将config.SSID字段设置为连接密码设备标识；
将config.wepKeys字段设置为连接密码password；将AuthAlgorithm字段设置为SHARED；
将GroupCipher设置为CCMP，再将GroupCipher设置为TKIP；
GroupCipher设置为WEP40，最后GroupCipher设置将WEP104；
将KeyMgmt设置为NONE；将wepTxKeyIndex字段设置为0；
将上述设置添加到wifi列表；
执行WifiConfiguration中的函数wifiManager.enableNetwork(wcgID,true)即可连接到目标设备的wifi。
(3)Type＝3，表示wifi为WPA加密类型，则在WifiConfiguration对象中按序进行如下操作：
将config.SSID字段设置为连接密码设备标识；
将config.wepKeys字段设置为连接密码password；
将AuthAlgorithm字段设置为OPEN；
将GroupCipher字段设置为TKIP；
将KeyMgmt字段设置为WPA_PSK；
将Protocol设置为WPA；
将GroupCipher字段设置为CCMP；
将PairwiseCipher字段设置为CCMP；
将status字段设置为ENABLED；
将上述设置添加到wifi列表；最后执行WifiConfiguration中的函数wifiManager.enableNetwork(wcgID,true)即可连接到目标设备的wifi。
当然，对于第一设备来说，不同的操作系统，其调用的无线连接API可能不同，具体的连接过程也不同，本申请不对其加以限制。
在本申请的一种优选实施例中，步骤120之前可以还包括如下步骤：
步骤114，通过音频接口发送音频连接测试信号；所述音频连接测试信号用于指示第一设备的连接对象返回音频响应信号；
在本申请实施例中，为了避免由于第一设备的音频接口接入的对象不是目标设备或者中继设备，本申请还通过音频接口向外发送信号，影响用户对其他设备(比如耳机)的使用，本申请首先检查第一设备的音频接口连接的是否为目标设备或中继设备，如果第一设备的音频接口连接的是目标设备或中继设备，则进入后续步骤。
在本申请实施例中，通过第一设备的音频接口向外发送音频连接测试信号，其中，上述音频连接测试信号用于指示第一设备的连接对象返回音频响应信号。那么，如果是本申请的目标设备或者中继设备接收到上述音频连接测试信号，则会针对上述音频连接 测试信号进行音频响应信号。如果不是本申请的目标设备或中继设备，则不会返回针对上述音频连接测试信号进行音频响应信号。
在具体实现中，以前述简单文本协议和2FSK机制为例，本申请可先构造类似“ceshi“\r\n”的连接测试指令，然后将“ceshi“\r\n”调制为音频连接测试信号，再将上述音频连接测试信号通过音频接口发出。
步骤116，检测音频接口是否接收到针对所述音频连接测试信号的音频响应信号；如果检测到针对所述音频连接测试信号的音频响应信号，则进入步骤110；如果检测到针对所述音频连接测试信号的音频响应信号，则停止后续执行过程。
在具体实现中，如前述例子，目标设备或者中继设备接收到包括“ceshi“\r\n”的音频连接测试信号后，先采用2FSK解调该音频连接测试信号，得到“ceshi“\r\n”，采用简单文本协议识别该指令，则会针对该指令返回一个音频响应信号。比如，生成音频响应信号指令“ok“\r\n”，再将“ok“\r\n”采用2FSK调制为音频响应信号，再将该音频响应信号通过音频线返回第一设备的音频接口。
第一设备在音频接口接收到上述音频响应信号之后，采用2FSK进行解调，获得“ok“\r\n”，那么通过简单文本协议识别该指令，就确认音频接口的连接对象为目标设备或者中继设备，那么可进入步骤110。
在具体实现中，本申请实施例可以设置一个时间间隔，比如设置时间间隔为5秒，在音频连接测试信号发出之后，如果5秒之内未接收到针对上述音频连接测试信号的音频响应信号，则停止后续执行过程。
可以理解第一设备发送音频连接测试信号采用的音频接口引脚与前述发送第一音频信号类似，第一设备接收音频响应信号所采用的音频接口引脚与前述接收第二音频信号类似。在此不在赘叙。
当然上述时间间隔可以根据需要进行设置，本申请不对其加以限制。
在第一设备与目标设备无线连接上之后，用户即可将音频插头从第一设备的音频接口中拔出。
通过本发明实施例，第一设备可以通过音频接口获取到其想要进行无线连接的目标设备的无线连接权限信息，然后自动根据无线连接权限信息与目标设备进行无线连接。用户的无线连接的操作简单，不需用户记忆和输入任何无线连接权限信息；其次，目标设备的无线连接权限信息在电路内部传输给第一设备，安全性高；再次，由于音频接口的应用范围广泛，从而本申请的应用范围也很广泛，适配性强。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请实施例并不受所描述的动作顺序的限制，因为依据本申请实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本申请实施例所必须的。
参照图2，其示出了本申请的一种设备接入方法的步骤流程图。
图2所示实施例对应图1所示实施例，从被连接的目标设备或中继设备一侧进行描述，具体可以包括如下步骤：
步骤210，检测是否接收到第一音频信号；所述第一音频信号用于指示获取目标设备的无线连接权限信息；若检测到第一音频信号，则进入步骤220；若未检测到第一音频信号，则不进行后续处理；
可以理解，本申请实施例的目标设备或者中继设备在接收到由第一设备发送的用于指示获取目标设备的无线连接权限信息的第一音频信号之后，会在对音频信号进行解析和处理，并根据相应执行逻辑返回第一设备所需求的目标设备的无线连接权限信息。
本申请实施例中，在目标设备或中继设备中会预置与第一设备一致的音频信号解析机制，使两侧可以正常进行通信。
由于第一设备的音频接口包括4个引脚：GND(地底线)、L(左声道)、R(右声道)和MIC(麦克风)。
可以理解，相应的在目标设备或者中继设备中，对应设置4个引脚，使第一设备和目标设备，或者第一设备和中继设备，可以通过音频线进行连接，并通过相应引脚接收信号。
当然，目标设备或者中继设备中的各引脚可以对外暴露的音频接口实现，此时，则可用两端均为音频插头的音频线，该音频线其中一端插头插入第一设备的音频接口，另一端插头插入目标设备或中继设备的音频接口，实现两侧的连接。目标设备或中继设备的各引脚也可与音频线相应引脚合在一起，音频线的另外一个插头暴露在外，此时，该插头插入第一设备的音频接口，实现两侧的连接。
在本申请的一个实施例中，对应于图1实施例的子步骤S124，调用音频输出API，通过音频接口的左声道引脚和/或右声道引脚，经由音频线将上述第一音频信号发出。在本申请实施例中，上述步骤210包括：
子步骤S211，在左声道引脚和/或右声道引脚检测是否接收到第一音频信号。
可以理解，目标设备或者中继设备则通过相应的左声道引脚和/或右声道引检测是否接收到第一音频信号。
步骤220，针对第一音频信号进行处理，获得第二音频信号；所述第二音频信号包括目标设备的无线连接权限信息；
在获得第一音频信号之后，即可对第一音频信号进行处理，根据第一音频信号中获取目标设备的无线连接权限信息的指示，获取目标设备的无线连接权限信息以生成第二音频信号，从而，上述第二音频信号包括了目标设备的无线连接权限信息。
在本申请的一个实施例中，如图1实施例中的，述第一音频信号中包括权限获取指令；
相应的，上述步骤220包括：
子步骤S221，对接收到的所述第一音频信号进行解调，获得权限获取指令；
在具体实现中，采用与第一设备一致的调制调解方式和指令协议。如图1实施例中使用的2FSK和简单文本协议。那么对于包括权限获取指令“getssid:+Equipment info+“\r\n”的第一音频信号进行解调，获得“getssid:+Equipment info+“\r\n”。
子步骤S222，根据所述权限获取指令，获取目标设备的无线连接权限信息；
如前述权限获取指令“getssid:+Equipment info+“\r\n”，根据简单文本协议识别该权限获取指令，则调用相应逻辑获取目标设备的无线连接权限。对应于“getssid:+Equipment info+“\r\n”，则获取目标设备的ssid和连接密码password。
子步骤S223，生成包括所述无线连接权限信息的返回指令；
如前述例子，在获取到目标设备的ssid和连接密码password，根据简单文本协议生成返回指令“ssid+password“\r\n”。
子步骤S224，将所述返回指令调制为第二音频信号。
如前述例子，将返回指令“ssid+password“\r\n”采用2FSK调制为第二音频信号。
步骤230，将所述第二音频信号返回第一设备，以使第一设备根据所述第二音频信号中的无线连接权限信息，将所述第一设备与目标设备进行无线连接。
在目标设备或者中继设备生成第二音频信号之后，即可将第二音频信号由音频线返回第一设备的音频接口中。
在本申请的一个实施例中，步骤230可以包括如下子步骤：
子步骤S231，通过麦克风引脚将所述第二音频信号返回第一设备。
在一种情况下，第一设备可通过麦克风引脚接收音频输入的，那么目标设备或者中继设备则将第二音频信号通过其麦克风引脚输出，然后由音频线的麦克风线传输到第一设备的麦克风引脚。
进而，第一设备则可通过子步骤S131，调用音频输入API，从音频接口的麦克风引脚中接收上述第二音频信号。
在本申请的一个实施例中，在步骤210之前还包括：
步骤202，检测是否接收到音频连接测试信号；所述音频连接测试信号用于指示第一设备的连接对象返回音频响应信号；若检测到所述音频连接测试信号，则进入步骤204；若未检测到所述音频连接测试信号，则不进入后续执行过程；
步骤204，返回针对所述音频连接测试信号的音频响应信号。
如前述步骤116中，第一设备发送的包括“ceshi“\r\n”的音频连接测试信号之后，本申请实施例则解调音频连接测试信号，获得音频响应信号指令“ceshi“\r\n”，然后根据简单文本协议识别并执行该指令，生成音频响应信号指令“ok“\r\n”，再将“ok“\r\n”采用2FSK调制为音频响应信号，再将该音频响应信号通过音频线返回第一设备的音频接口。
另外，在本申请实施例中，对于目标设备，还可自动定时修改无线连接权限信息。比如修改无线连接权限信息中的连接密码。那么每次无线连接权限修改后，第一设备则自动断开与目标设备的无线连接。如此，加强了目标设备的无线连接的安全性。
在实际应用中，可以在目标设备中设置动态口令(如One-time Password)，动态更新目标设备的连接密码。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请实施例并不受所描述的动作顺序的限制，因为依据本申请实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本申请实施例所必须的。
