I am new to java programming. I have used smsj api to send messages from pc to mobile through a gsm modem. I have succesfully been able to send plain text messages using SmsSender.sendTextSms(msg, reciever, sender) as well as unicode messages using SmsSender.sendUnicodeTextSms("smsj हिन्दी मेसेज", reciever);.
They say it supports EMS messages too. I am trying to send picture messages (black and white), and audio clips through this. But i cannot figure out how to do this.
The documentation shows that there is a class EmsMessage that implements SmsMessage But i couldn't find any details on how to use it. I have also gone through its forum but again cant find any solution.
Hoping someone could guide me on this.
this is my code for sending text messages..
public class SendMessage {
public void send() {
try{
SmsSender smsSender = SmsSender.getGsmSender("COM14");
String msg ="smsj test message";
String reciever = "919790968633";
String sender ="919176968289";
smsSender.connect();
smsSender.sendTextSms(msg, reciever, sender); //simple text message
smsSender.sendUnicodeTextSms("smsj हिन्दी मेसेज", reciever); //unicode message
smsSender.disconnect();
} catch(IOException i){
i.printStackTrace();
System.out.println("i");
} catch(SmsException s){
s.printStackTrace();
System.out.println("s");
}
}
public static void main(String args[]){
SendMessage app = new SendMessage();
app.send();
}
}
i tried this code for sending ems message.. but it seems to be wrong.
EmsMessage ems = new EmsMessage();
ems.addText(msg);
SmsMessage sms ;
sms=ems;
smsSender.sendSms(sms, reciever, sender);
i get this error message:
60 [main] INFO org.marre.sms.transport.gsm.SerialComm - >> AT+CMGF=0
261 [main] INFO org.marre.sms.transport.gsm.SerialComm - <<

at org.marre.SendMessage.main(SendMessage.java:58)
Can anyone help me what is the correct syntax of using this EmsMessage and SmsMessage class?
