windows短信猫二次开发

短信猫

短信猫用于批量收/发短信或其它SIM卡服务。

短信猫与PC通过GSM无线网络交互。

交互过程可以分为三个层次：

1.物理层，即无线网络通信。

2.指令层，短信猫支持M35AT指令。

3.应用层，APP需要与短信猫交互的内容。

在做二次开发过程中，真正需要关心的只是应用层的内容。为了避免重复开始，关于物理层和指令层，可以直接使用现有的开源项目。而二次开发的代码只需要调用指令层的API即可。

一、搭环境

1、物理层开源项目Rxtx

这一层的主要工作是实现JAVA的串口通信。

开源项目Rxtx和Win32Com都能完成这样的功能。其中Win32Com只支持32位Windows，而Rxtx可以支持32位和64位的Windows和linux，因此本文选择了Rxtx。

步骤：

下载rxtxSerial.dll并复制到JAVA_HOME\bin目录下

下载RXTXcomm.jar，并导入到项目中

2、指令层开源项目Smslib

这一层的主要工作是把用户可能会用到的操作（例如连接猫池、发短信、收短信等）封装成猫所支持的AT指令，通过rxtx发出去。

步骤：

从smslib官网下载SMSLib (Java - jar file) v3.5.4

解压，把jar包导入到项目中

二、编程

满满的都是套路。

0.检测可用的端口

public void findComm()
{
static int bauds[] = { 9600, 19200, 57600, 115200 };
Enumeration<CommPortIdentifier> portList = CommPortIdentifier
. getPortIdentifiers();
System. out.println( "短信设备端口连接测试..." );
//connect("COM13", 115200);
while (portList.hasMoreElements()) {

CommPortIdentifier portId = (CommPortIdentifier) portList
.nextElement();

if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL ) {
System. out.println( "找到串口：" + portId.getName());

for ( int i = 0; i < bauds. length; i++) {
System. out.print( "  Trying at " + bauds [i] + "..." );
SerialPort serialPort = null;
try {
InputStream inStream;
OutputStream outStream;
int c;
String response;
serialPort = (SerialPort) portId.open(
"SMSLibCommTester" , 1000);
serialPort
.setFlowControlMode(SerialPort.FLOWCONTROL_RTSCTS_IN );
serialPort.setSerialPortParams(bauds [i],
SerialPort. DATABITS_8 , SerialPort.STOPBITS_1 ,
SerialPort. PARITY_NONE );
inStream = serialPort.getInputStream();
outStream = serialPort.getOutputStream();
serialPort.enableReceiveTimeout(1000);
c = inStream.read();
while (c != -1)
c = inStream.read();
outStream.write( 'A');
outStream.write( 'T');
outStream.write( '\r');
try {
Thread. sleep(1000);
} catch (Exception e) {
}
response = "";
c = inStream.read();
while (c != -1) {
response += ( char) c;
c = inStream.read();
}
if (response.indexOf( "OK" ) >= 0)
{
portname = portId.getName();
baud = bauds [i];
System. out.println( "找到设备：" + portname + baud);
break;
} else
System. out.println( "  没有发现设备!" );
} catch (Exception e) {
System. out.println( "  没有发现设备!" );
}
finally{
serialPort.close();
}
}
}
}
}

1、连接猫池

public void connect()
{
// Create the notification callback method for inbound & status report
// messages.
//InboundNotification inboundNotification = new InboundNotification();
// Create the notification callback method for inbound voice calls.
CallNotification callNotification = new CallNotification();
//Create the notification callback method for gateway statuses.
GatewayStatusNotification statusNotification = new GatewayStatusNotification();
OrphanedMessageNotification orphanedMessageNotification = new OrphanedMessageNotification();
try
{
System.out.println(Library.getLibraryDescription());
System.out.println("Version: " + Library.getLibraryVersion());
// Create the Gateway representing the serial GSM modem.
SerialModemGateway gateway = new SerialModemGateway("modem.com1", portname, baud, "Wavecom", "");
// Set the modem protocol to PDU (alternative is TEXT). PDU is the default, anyway...
gateway.setProtocol(Protocols.PDU);
// Do we want the Gateway to be used for Inbound messages?
gateway.setInbound(true);
// Do we want the Gateway to be used for Outbound messages?
gateway.setOutbound(true);
// Let SMSLib know which is the SIM PIN.
gateway.setSimPin("1234");
// Set up the notification methods.
//Service.getInstance().setInboundMessageNotification(inboundNotification);
Service.getInstance().setCallNotification(callNotification);
Service.getInstance().setGatewayStatusNotification(statusNotification);
Service.getInstance().setOrphanedMessageNotification(orphanedMessageNotification);
Service.getInstance().S.SERIAL_POLLING = true;  //hyn 启用轮循模式
// Add the Gateway to the Service object.
Service.getInstance().addGateway(gateway);
// Similarly, you may define as many Gateway objects, representing
// various GSM modems, add them in the Service object and control all of them.
// Start! (i.e. connect to all defined Gateways)
Service.getInstance().startService();
// Printout some general information about the modem.
System.out.println();
System.out.println("Modem Information:");
System.out.println("  Manufacturer: " + gateway.getManufacturer());
System.out.println("  Model: " + gateway.getModel());
System.out.println("  Serial No: " + gateway.getSerialNo());
System.out.println("  SIM IMSI: " + gateway.getImsi());
System.out.println("  Signal Level: " + gateway.getSignalLevel() + " dBm");
System.out.println("  Battery Level: " + gateway.getBatteryLevel() + "%");
System.out.println();
// In case you work with encrypted messages, its a good time to declare your keys.
// Create a new AES Key with a known key value.
// Register it in KeyManager in order to keep it active. SMSLib will then automatically
// encrypt / decrypt all messages send to / received from this number.
Service.getInstance().getKeyManager().registerKey("+306948494037", new AESKey(new SecretKeySpec("0011223344556677".getBytes(), "AES")));
}
catch (Exception e)
{
e.printStackTrace();
}
}

这段代码可以直接拿来用，只有一个地方要改，且很容易出现错误。

SerialModemGateway gateway = new SerialModemGateway("modem.com1", portname, baud, "Wavecom", "");

参数1：”modem.com1”

这是这次串口连接的名字，用于与其它的串口连接区分，没有格式要求，但是要唯一。

参数2：portname

串口的名字，可以从设备管理器中查出来，也可以通过上面的“检测可用的端口”程序检测出来。在windows上一般是“COMxx”。

参数3：波特率

9600, 19200, 57600, 115200。一般是115200。从设备管理器上查出来的似乎不准，可以用“检测可用的端口”程序检测出来。

参数4：制造商

smslib支持的制造商可以从org.smslib.modem.athandler查到。



最常见的是”Huawei”和”Wavecom”

参数5：型号

smslib支持的型号可以从org.smslib.modem.athandler查到。

也可以填”“。

2.发短信

public void sendMessage(String target, String content) throws Exception
{
OutboundMessage msg = new OutboundMessage(target, content);
Service.getInstance().sendMessage(msg);
System.out.println(msg);
}

3.收短信

public void readMessage(){
try
{
// Define a list which will hold the read messages.
List<InboundMessage> msgList;
System.out.println("Example: Read messages from a serial gsm modem.");
// Read Messages. The reading is done via the Service object and
// affects all Gateway objects defined. This can also be more directed to a specific
// Gateway - look the JavaDocs for information on the Service method calls.
msgList = new ArrayList<InboundMessage>();
Service.getInstance().readMessages(msgList, MessageClasses.ALL);
for (InboundMessage msg : msgList)
System.out.println(msg);
}
catch (Exception e)
{
e.printStackTrace();
}
}

4.断开连接

Service.getInstance().stopService();

三、踩过的坑

1.No device response.

制造商填错了

2.flush

波特率填错了。

开始按照设备管理器里查出来的波特率填的，一直报这个错误。改成另一个值就好了。可见设备管理器里查出来的不准。

3.write

1.设备没连好

2.信号不好，表现为灯常亮，正常应该灯闪

3.不知道原因，重启一下就好了

4.串口被占
