from java-gsm-at-ussd.

Thanks appreciate it

from java-gsm-at-ussd.

hey sorry bother you again, i'm really stuck at the reading part and confused, hoping you could help me.

from java-gsm-at-ussd.

Hi,
I almost done, I will update the library soon.
Sorry about that.

from java-gsm-at-ussd.

@elvindeguzman
I update the code with fixes and added an example class.
Try it please.
Thanks

from java-gsm-at-ussd.

appreciate it so much!

from java-gsm-at-ussd.

its sending the sms but I'm still having issue reading the sms

from java-gsm-at-ussd.

Could you please share the output

from java-gsm-at-ussd.

looks like the event data registering is not getting the response like the +CMGL

I tried changing the listener to this:

            @Override
            public int getListeningEvents() {
                return SerialPort.LISTENING_EVENT_DATA_RECEIVED;
            }
            
            
            @Override
            public void serialEvent(SerialPortEvent event) {
            	result="";
                byte[] msg = event.getReceivedData();
                serialPort.readBytes(msg, msg.length);
                StringBuffer sb = new StringBuffer();
                for (int i = 0; i < msg.length; i++) {
                	char charVal = (char)msg[i];
                	System.out.println("msg["+i+"] : "+charVal);
                	sb.append(charVal);
				}
                logger.info("serial event = "+sb.toString());
                
                result = sb.toString();
            }

The only issue i'm having is sometimes the strings get cut for example when executing the command AT+CMGR=1 it should give me something like +CMGR: "REC UNREAD","+9999999999",,"21/03/30,04:39:39+32"
;1000000249;test;xxxxxx,5009;TCP;00002; but i'm getting some like the cut version of that string for example TCP:0002

from java-gsm-at-ussd.

I think it's modem model related

from java-gsm-at-ussd.

I'm using wavecom modem

from java-gsm-at-ussd.

Could you debug the example and see the content of strs?

I'm not sure why the buffer is getting cut

from java-gsm-at-ussd.

Looks like using byte delimited listener is what I need. I created something like this:

final class MessageListener implements SerialPortMessageListener
{
@OverRide
public int getListeningEvents() { return SerialPort.LISTENING_EVENT_DATA_RECEIVED; }

@OverRide
public byte[] getMessageDelimiter() { return new byte[] { (byte)0x0D0A }; }

@OverRide
public boolean delimiterIndicatesEndOfMessage() { return true; }

@OverRide
public void serialEvent(SerialPortEvent event)
{
StringBuffer sb = new StringBuffer();
byte[] delimitedMessage = event.getReceivedData();
for (int i = 0; i < delimitedMessage.length; i++) {
char charVal = (char)delimitedMessage[i];
sb.append(charVal);
}
System.out.println("event value is "+sb.toString());
}
}

Yes it may help

from java-gsm-at-ussd.

It may be also something related to the baudrate.

from java-gsm-at-ussd.

Try execute this
AT+IPR=?

from java-gsm-at-ussd.

+IPR: (0,2400,4800,9600,19200,38400,57600),(300,600,1200,115200)
I'm using 115200 baud rate

from java-gsm-at-ussd.

The default for the serial library is 9600

from java-gsm-at-ussd.

Change it, and try again

from java-gsm-at-ussd.

yep i change it and was using the 115200 and same issue

from java-gsm-at-ussd.

Try this
AT+IPR?

from java-gsm-at-ussd.

+IPR: 115200

from java-gsm-at-ussd.

Can you try with serial communication application like putty?

from java-gsm-at-ussd.

yep i'm using that and seems to be working properly on putty, no issue there, i'm also using 115200 rate when connecting using putty

from java-gsm-at-ussd.

Try reduce the baudrate speed

from java-gsm-at-ussd.

tried lower baudrate speed still no luck :(

from java-gsm-at-ussd.

were you able to send ?
