java - 使用 Java 将命令发送到 gsm 调制解调器

我正在尝试制作一个发送短信的程序。我编写了程序,但没有成功发送消息。我的程序向计算机中的端口 COM 发送一个 At 命令,但我的 gsm 调制解调器没有得到响应。我正在使用 COM 终端(Temp pro...)通过 at 命令发送短信,我能够发送短信。因此我不知道为什么程序不能发送短信。

import java.io.*;
import java.util.*;
import gnu.io.*;

public class prawiefinal {
static Enumeration portList;
static CommPortIdentifier portId;
static String messageString = "AT+CMGF=1 \r";
static String messageString2 = "AT+CMGS=\"+4866467xxxx\"\r";
static String messageString3 = "TESting \u001A\r\n";
static SerialPort serialPort;
static OutputStream outputStream;


public static void main(String[] args) throws InterruptedException {
portList = CommPortIdentifier.getPortIdentifiers();

while (portList.hasMoreElements()) {

portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {

if (portId.getName().equals("COM3")) {

try {
serialPort = (SerialPort)
portId.open("COM3", 2000);
} catch (PortInUseException e) {System.out.println("err");}
try {
outputStream = serialPort.getOutputStream();
} catch (IOException e) {e.printStackTrace();}
try {
serialPort.setSerialPortParams(9600,
SerialPort.DATABITS_8,
SerialPort.STOPBITS_1,
SerialPort.PARITY_NONE);
} catch (UnsupportedCommOperationException e) {e.printStackTrace();}
try {
outputStream.write(messageString.getBytes());
Thread.sleep(3000);
outputStream.flush();

outputStream.write(messageString2.getBytes());
Thread.sleep(3000);
outputStream.flush();

outputStream.write(messageString3.getBytes());
Thread.sleep(3000);
outputStream.write(26);
outputStream.flush();
System.out.println(messageString);
Thread.sleep(3000);






outputStream.close();
serialPort.close();

} catch (IOException e) {e.printStackTrace());}
}
}
}
}
}

最佳答案

好的,我制作了程序,我可以发送短信了。我使用 CTRL+Z 和 Enter 那是个问题。 :D

import java.io.*; 
import java.util.*;
import gnu.io.*;

public class SMSsender {
static Enumeration portList;
static CommPortIdentifier portId;
static String messageString1 = "AT";
static String messageString2 = "AT+CPIN=\"7078\"";
static String messageString3 = "AT+CMGF=1";
static String messageString4 = "AT+CMGS=\"+4866467xxxx\"";


static String messageString5 = "TESTY2";
static SerialPort serialPort;
static OutputStream outputStream;
static InputStream inputStream;
static char enter = 13;

static char CTRLZ = 26;
public static void main(String[] args) throws InterruptedException {
portList = CommPortIdentifier.getPortIdentifiers();



while (portList.hasMoreElements()) {

portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {

if (portId.getName().equals("COM3")) {

try {
serialPort = (SerialPort)
portId.open("COM3", 2000);
} catch (PortInUseException e) {System.out.println("err");}
try {
outputStream = serialPort.getOutputStream();
inputStream = serialPort.getInputStream();
} catch (IOException e) {e.printStackTrace();}
try {
serialPort.setSerialPortParams(9600,
SerialPort.DATABITS_8,
SerialPort.STOPBITS_1,
SerialPort.PARITY_NONE);
} catch (UnsupportedCommOperationException e) {e.printStackTrace();}
try {

outputStream.write((messageString1 + enter).getBytes());


Thread.sleep(100);
outputStream.flush();

outputStream.write((messageString2 + enter).getBytes());

Thread.sleep(100);
outputStream.flush();

outputStream.write((messageString3 + enter).getBytes());

Thread.sleep(100);
outputStream.flush();




outputStream.write((messageString4 + enter).getBytes());

Thread.sleep(100);
outputStream.flush();

outputStream.write((messageString5 + CTRLZ).getBytes());

outputStream.flush();
Thread.sleep(100);


System.out.println("Wyslano wiadomosc");
Thread.sleep(3000);


outputStream.close();
serialPort.close();
System.out.println("Port COM zamkniety");

} catch (IOException e) {e.printStackTrace();}
}
}
}

}}
