Building Java Dekstop App for SMS gateway using GSM modem

Getting Started

These app send bulk SMS using GSM Modem (tested using Wavecom and Syscom MP8P) in this project there is 3 main class:

• SMSPanel (the Main Interface)
• SMSSender (class that contain methods for send SMS)
• SMSCommand (class that contain AT-COMMANDs for send command to modem)

Code

this app built using RXTXcomm lib to connect java app with GSM Modem (lib included in project). first, it will identified all communication port, then open selected port the serial port will receive command (AT COMMAND) via OutputStream and InputStream

get all communication port using this code

portList = CommPortIdentifier.getPortIdentifiers();

set modem baud rate, databits, stopbits, and parity using this code

serialPort.setSerialPortParams(115200,
    SerialPort.DATABITS_8,
    SerialPort.STOPBITS_1,
    SerialPort.PARITY_NONE);

to send single SMS, use this simple raw AT COMMAND

AT
AT+CMGF=1
AT+CMGS="[phone]" //replace with recipient number

if you using netbeans, chang run setting by right click on project -> properties -> Run. in VM Options add this -Djava.library.path=/usr/lib/jni then click OK

if you can't detect port then the port might be not granted permission, use this command in terminal

sudo chmod 666 /dev/ttyUSB0

or change /dev/ttyUSB0 with your connected port
