Hello, I use opensmpp and try the submit method (Submit_SM) and it work fine. But later i discover that i must use the deliver method (Deliver_SM) in order to use the listener side of the ESME and receive the message from the SMSC.
Here is my code the bind work fine but the response from the deliver method is always null.
Please if anyone can help me or at least give me a little example whith the deliver method
PS: I use the synchronous mode.

I have build an application to sending short messages using smpp 3.4 and that work fine, but in some phones model like nokia 220 i got this message:

Can not display this message

in my phone.
this is my function source code :

public String sendMsg(JsonObject paramsIN) {
    String smsMessage = paramsIN.getString("body");
    String smsDestination = paramsIN.getString("to");
    String smsSource = paramsIN.getString("from");
    String smscNAME = paramsIN.getString("smsc");

    SubmitSM request = new SubmitSM();
    SubmitSMResp response;
    Session session;
    try {
        request.setSourceAddr(smsSource);
        request.setDestAddr(smsDestination);
        request.setShortMessage(smsMessage, "UTF-8");
        request.setRegisteredDelivery((byte) 3);
        request.setDataCoding((byte) 4); // 4
        request.assignSequenceNumber(true);
        response = ((Session) sd.get(smscNAME)).submit(request);
        logger.info("Submit response " + response.debugString());
        String messageId = response.getMessageId();       

        BigInteger bigInt = new BigInteger(messageId, 16);  

        return bigInt+"";
    } catch (WrongLengthOfStringException e) {
        logger.error(e);
        return null;
    } catch (PDUException e) {
        logger.error(e);
        return null;
    } catch (TimeoutException e) {
        logger.error(e);
        return null;
    } catch (WrongSessionStateException e) {
        logger.error(e);
        return null;
    } catch (IOException e) {
        logger.error(e);
        return null;
    }
}

Will no data interaction between ESME SMSC break the binding of SMSC.
Thank you very much!

Are socket connections and SMSC connections synchronized？
When you open a connection, two are on simultaneously, and when you close a connection, two are off simultaneously？
Thank you ！

Hello
i have a problem with your library.
in some moment I stop receiving packets Enquirelink SumbitSm-resp and others in my PDU Lintener class, when i restarting app i am getting well all packages
What i do wrong?

Hello,
We have been using opensmpp library for some of our applications for quite some time. We are facing a unique issue, when sending sms in unicode, sms when sent using Hindi or Telugu languages its delivering fine, but when sending using Gujarathi or Tamil the messages are garbled at the end handset.
We tried to analyse the issue and found that, when the message data is being converted to byes using .getBytes("ASCII") the specific language content is getting garbled with either ? or something else. We assume this is a encoding/charset issue, any help in this regard would be appreciated ?
Also has anyone faced or fixed issues in the lib in this regard ?
Do let us know if you need more information to be able to help us with a possible solution.
Thanks

Hi All,

I've faced with the problem when sending response for DeliverSM.

There is random delay (up to the several second) between invocation Session.respond() and real sending it's' packet through the network interface.

I checked by it using network packet sniffer.

I've reviewed sources but not found any parts of code which could be a potencial reason for such strange delays.. (

Is anybody knows about any reason (and solution) for this situation ?

Thank you in advance,
Roman

while sending number of Submit_sm requests not getting same count of delivery receipts/ Delivery_sm responses. getting very low Delivery_sm responses.

Command mentioned in the javadoc of the Simulator class is

java -cp smpp.jar:smscsim.jar org.smpp.smscsim.Simulator

is not working and i also tried

java -cp D:\logica-smpp-sim-master\smscsim.jar;.;D:\logica-smpp-sim-master\smpp.jar org.smpp.smscsim.Simulator

The above command is also not working .

Kindly help me to start the simulator

The website for opensmpp says it only supports v3.4. Is this still true, or does opensmpp now support v5.0? Thanks

I'm using opensmpp for sending sms. But I'm not able to send sms more than 255 characters. Messages are not getting sent for more than 255 characters. can you please suggest how to use optional parameters with TLV to send the same.

Does this open source project support long connections? How to transform without support? Anybody know?
Thank you very much!

we are using opensmpp as part of upgrade from Logica smpp to opensmpp and its working fine for sometime but suddenly getting the ERROR: Not connected Exception: java.io.IOException: Not connected in application logs.
After restart the application again it working fine and after sometime again same error throwing..

Can anyone help on it please ?

how can i execute from command line?

java -classpath ./ SMPPSender
Error: No found or load the main class SMPPSender

I tried the simulator on 2 servers: one is mine (Debian Sid), the other is my office's (Ubuntu).
On my server, the simulator runs fine. No problem so far. But on my office's, I faces an issue when choosing bind:

1
Asynchronous/Synchronnous Session? (a/s) [s]
Transmitter/Receiver/Transciever (t/r/tr) [t]
IP address of SMSC [142.88.100.56]
Port number [2557] 2557
Your system ID [pavel]
Your password [dfsew]
Bind request (bindreq: (pdu: 0 2 0 [1]) pavel dfsew 52 (addrrang: 1 1 ) )
Bind operation failed. java.net.ConnectException: Connection timed out: connect

What do possibly cause this connection timed out issue? Both simulators use the same config. Mine runs JDK 8, my office's runs JDK 9.

When encoding, '€' (euro sign) is treated as an unmappable character instead of being mapped to {0x1b, 0x65}. When decoding, {0x1b, 0x65} is translated into ' ' (space) instead of '€'.

When a character buffer with only basic GSM characters and a byte buffer of insufficient size is provided as argument to Gsm7BitEncoder.encode(), the return value is CoderResult.UNDERFLOW but it should be CoderResult.OVERFLOW. Vice versa, GSM7BitDecoder.decode() returns CoderResult.UNDERFLOW even though a character buffer of insufficient size is provided as argument.

We are sending high throughput SUBMIT_SM using OpenSMPP. But TCP ZeroWindow is received most of the times. Deliver_SM and SUBMIT_SM_RESP is getting missed. Please suggest how to resolve this.

TPS: 1000 msg/s for SUBMIT_SM and similar is on PDUListerener(DeliverSM/SUBMIT_SM_RESP)

The method appendCString adds a string as ASCII, in the time the method removeCString reads one as GSM7BIT, although it should use ASCII.

A next trouble follows from this issue: If we try to connect some EMSE using OpenSmpp to some SMSC using OpenSmpp and we use special symbols in login/password like '[]-' then login/password will be different in BindRequest and BindResponse entities.

Sorry guys but I have this issue...
Bind request (bindreq: (pdu: 0 2 0 [1]) pavel dfsew 52 (addrrang: 1 1 ) )
Bind operation failed. java.net.ConnectException: Connection refused: connect

I can't send any sms. Maybe I forget some configuration. Is there some doc to understand how to implement/set all parameters?
Thanks

I brought a piece of my code.

if pdu.isOK() value is false ====> this.failSendCount++

And I will put the failed number in this.phoneNumbers.add("1000000000"); and store it in database

I would like to get a phone number for which texting failed.

In this.phoneNumbers.add ("1000000000") we will put the phone number that failed to transmit.

How can I get the number that failed to transfer?

How can I be sure that there is no data interaction between ESME and SMSC？
Thank you very much!

How to make a long connection？

Hello,

i am able to send SMS Successfully. but i am not receiving SMS

this is my code to receive PDU

try {
while (true) {
try {
System.out.println("SMSCSession going to receive a PDU");
pdu = session.receive(30000);
} catch (Exception e) {
System.out.println("SMSCSession caught exception receiving PDU " + e.getMessage());
}
if (pdu != null) {
timeoutCntr = 0;
if (pdu.isRequest()) {
System.out.println("SMSCSession got request " + pdu.debugString());

                } else if (pdu.isResponse()) {
                    System.out.println("SMSCSession got response " + pdu.debugString());

                } else {
                    System.out.println("SMSCSession not reqest nor response => not doing anything.");
                }
            }
        }

any docs on how to config and start the SMSC server ?!

Hi Team,
There is no main class available how to run the application in local?

We need support for establishing an outbound connection through a proxy server.
Is there already a mechanism in place to do this that I might have overlooked? If now, I'd be happy to submit a PR

The Logica link on (gh-pages) index.md now redirects right back to us.

Can anyone explain how does the below timeout works?

• RECEIVER_TIMEOUT = 60000;
• CONNECTION_RECEIVE_TIMEOUT = 10000;
• COMMS_TIMEOUT = 2000;
• QUEUE_TIMEOUT = 2000;
• ACCEPT_TIMEOUT = 60000;
• CONNECTION_TIMEOUT = 60000;

I try to make the connection expired in 6 seconds but the connection will hit more than 1 minutes for some of my transactions

Link to opensmpp-sim on page http://opensmpp.org/downloads.html leads to https://repo1.maven.org/maven2/org/opensmpp/opensmpp-sim/3.0.0/opensmpp-3.0.0.jar but should lead to https://repo1.maven.org/maven2/org/opensmpp/opensmpp-sim/3.0.0/opensmpp-sim-3.0.0.jar

Using the original Logica SMPP (precursor to OpenSMPP) code in an SMPP server implementation, it was observed that some threads would occasionally cause 100% CPU load for a 60 second period, when a particular SMPP client tried to connect, but failed because the bind request was deemed invalid.

This particular client seemed to not shut down the TCP session timeously, which caused a race condition that could occasionally lead to Thread.yield() being run in a tight loop in ProcessingThread, waiting for TCP socket shutdown.

During periods of high CPU load, thread dumps showed threads that persisted in this state for ~60 seconds:

   java.lang.Thread.State: RUNNABLE
        at java.lang.Thread.yield(Native Method)
        at com.logica.smpp.util.ProcessingThread.stop(ProcessingThread.java:165)
        at com.logica.smpp.Receiver.stop(Receiver.java:234)
        at <some code that tries to stop() a Receiver>

The same code still exists in OpenSMPP, and should be fixed (Thread.yield replaced with Thread.sleep) here too.

Internal issue tracker ref: TP-6228.

I'm not familiar with java or maven, so please give me a light to start the instalation and configuration of this package.

thanks.

Hello All,
Anyone using this library is aware how to set window size or Throttle TPS based on the Server we connect to, to ensure we send not more than the configured TPS.
Any insight is really appreciated.
Regards,
Kiran

When stopping a Session or stopping an SMSCListener, an ongoing socket operation (reading, in the first case and accepting, in the second case) can delay the termination for one minute (since the socket timeout is fixed at 60s).

By closing the Connection object (connection) on Session.unbind() and (serverConn) on SMSCListener.stop(), the socket operation will unblock and they will terminate.

This will prevent the unnecessary wait on either end of the connection.

Hi,

correct me if I'm wrong,

but, once I've downloaded smpp files on my server and once i've configured the smppsender.cfg file, the last thing i've to do is execute smppsender.sh?

It does appear an error when I'm doing that:

Error: main class not found or loaded org.smpp.client.SMPPSender

What is wrong here?

Kind regards.

The link to the README.md (to http://smstools.wiki.sourceforge.net/) no longer works - I get a Python permission error dump.

If you do not use unbind, will ESME and SMSC automatically disconnect if they are idle for a long time。
Thank you very much!
