下面结合说明书附图对本发明各实施例进行详细说明。
实施例一:
如图 1 所示, 为本发明实施例一中对上网设备进行初始化的方法示意 图, 所述方法包括以下步骤:
步骤 101 : 通信模块接收应用模块发送的 AT查询命令, 该 AT查询命
令用于请求获知通信模块的网络制式。
在本实施例一中, 所述应用模块是指上网设备中能够实现多种业务功 能的模块 , 通信模块是指能够与无线通信网络连接的内置或外接的模块。 通信模块的网络制式根据通信模块能够连接的网络不同而不同, 包括但不 限于码分多址 2000 ( CDMA2000 ) 网络制式和宽带分码多址( WCDMA ) 网络制式。
步骤 102: 通信模块向应用模块发送自身对应的网络制式信息。
步骤 103: 应用模块收到网络制式信息后, 确定与通信模块通信时的软 件版本, 以及向通信模块发送至少一个硬件配置信息。
所述硬件配置信息是由应用模块根据通信业务执行时的应用场景决定 的, 相应的应用场景对应着特定的硬件配置信息, 包括但不限于以下至少 一种信息: 应用模块和通信模块之间连接的通用输入输出 (GPIO )端口数 量、 有效电平信息、 上网设备睡眠时通用串行总线 (USB )端口是否断开 或语音通道信息。
在本实施例一中, 在不同的应用场景下, 利用无线通信网络实现网络 业务时需要的硬件配置信息也不同。例如:在某些应用场景下,需要的 GPIO 端口数量为 N、 有效电平信息为低电平下降沿有效、 语音通道为传输数字 音频的脉冲编码调制 (PCM )端口; 在另一些应用场景下, 需要的 GPIO 端口数量为 M、 有效电平信息为低电平上升沿有效、 上网设备睡眠时 USB 端口断开、 语音通道为模拟音频输入输出 ( LINE— IN/LINE— OUT )端口。
在步骤 103 中, 应用模块已经确定网络制式信息和硬件配置信息, 则 可以进行初始化操作。 本实施例中也不限于在通信模块进行初始化操作之 后, 应用模块再根据网络制式信息和硬件配置信息进行初始化操作。
步骤 104:通信模块从预先设定的初始化操作信息集合中确定与接收到 的硬件配置信息匹配的初始化操作信息。
所述初始化操作信息可以是对硬件设备进行初始化操作的程序代码。 假设通信模块接收到的硬件配置信息是 GPIO端口数量为 N、有效电平 信息为低电平下降沿有效、 语音通道为 PCM端口, 则确定的初始化操作信 息为: 激活 N个 GPIO端口的操作信息、 将低电平下降沿设置为有效电平 的操作信息和激活 PCM端口的操作信息。
步骤 105: 通信模块根据初始化操作信息进行初始化操作。
在本步骤中, 通信模块调用确定的初始化操作信息 (即初始化操作的 程序代码), 完成对各硬件设备的初始化操作。
需要进一步说明的是: 在执行步骤 101 之前, 当上网设备开机时, 应 用模块和通信模块都进入正常开机初始化流程, 应用模块与通信模块首先 应该进行连接, 当应用模块与通信模块成功建立 AT连接之后, 再执行步骤 101。 因此, 在步骤 101之前还可以包含以下步骤:
步骤 100a: 应用模块利用通用异步收发器(UART )端口向通信模块发 送用于连接的 AT测试命令。
步骤 100b: 应用模块判断在设定时间内是否接收到通信模块返回的响 应消息。
步骤 100c: 若接收到响应消息, 应用模块则通过所述 UART端口向通 信模块发送 AT查询命令, 然后执行步骤 101。
步骤 100d: 若没有接收到响应消息, 应用模块则通过 USB端口向通信 模块发送 AT查询命令, 然后执行步骤 101。
在步骤 100d中, 如果通过 UART端口首次向通信模块发送 AT测试命 令后的设定时间内没有收到响应消息, 则可以有两种操作方式:
一种操作方式是确定应用模块和通信模块之间的 UART端口未导通, 另外釆用 USB端口通信。
另一种操作方式是通过 UART端口重传 AT查询命令,判断重传的次数
是否达到阔值, 如果重传的次数达到阔值(如达到 3次), 仍未收到响应消 息, 则另外釆用 USB端口通信; 如果重传的次数未达到阔值, 且收到响应 消息, 则可以通过所述 UART端口向通信模块发送 AT查询命令。
通过本发明实施例一的方案, 应用模块和通信模块在进行初始化配置 时, 通信模块无需针对不同硬件端口和参数开发相应的软件版本, 而只需 要根据应用模块发送的硬件配置信息直接对通信模块的硬件上网设备进行 初始化配置, 减少了软件开发的工作量, 降低了系统维护和管理的复杂度, 同时应用模块也可以使用同一套代码适配不同网络制式的通信模块。
实施例二:
本发明实施例二通过具体的实例对本发明实施例一的方案进行详细说 明。 假设在本实施例二中, 通信模块的网络制式为 EVDO制式, 如图 2所 示, 实施例二的方案如下:
第一步:应用模块通过 UART端口向通信模块发送 AT测试命令( AT ), 查询应用模块和通信模块之间的通道是否正常。
第二步:在应用模块与通信模块之间的 UART端口的连接通道正常时, 通信模块向应用模块返回响应消息 (OK )。
第三步: 应用模块通过 UART 端口向通信模块发送 AT 查询命令 ( ATE+NETTYPE? ), 请求获知通信模块的网络制式。
第四步: 通信模块向应用模块返回自身的网络制式信息(+NETTYPE: EVDO ), 表明通信模块的网络制式为 EVDO。
第五步:应用模块通过 AT配置命令发送硬件配置信息 1 : AT+GPIO=l , 0。 其中, 第一个参数 1表示 4个 GPIO , 第二个参数 0表示 GPIO低电平 或下降沿有效。
第六步: 通信模块返回响应消息(OK ), 并调用激活 GPIO端口的代码 和设置低电平的下降沿有效的代码。
第七步: 应用模块通过 AT 配置命令发送硬件配置信息 2 : AT+USBSLEEP=1 , 表示在上网设备睡眠时断开 USB连接。
第八步: 通信模块返回响应消息 (OK ), 并设置上网设备睡眠时断开 USB连接的代码。
本步骤在上网设备睡眠时断开 USB连接, 刻意降低待机时的电流。 第九步: 应用模块通过 AT 配置命令发送硬件配置信息 3 : AT+AUDIOCHAN=PCM , 表示语音通过 PCM端口传输。
第十步: 通信模块返回响应消息(OK ), 并调用激活 PCM端口的代码, 即将音频通道参数设置为 PCM端口。
