dlr gives error that message_state missing

[adeshpandey]

Hi, I have tried this package to send sms with smpp but it does not give me delivery reports of the messages. I have used the exact code format mentioned in the README which looks like:

larvitsmpp.client({
    'host': 'SMPP_URL',
    'port': SMPP_PORT,
    'username': 'SMPP_USER',
    'password': 'SMPP_PASS'
}, function(err, clientSession) {
    if (err) {
        throw err;
    }

    clientSession.sendSms({
        'from': 'PROMOTIONAL_ID',
        'to': 'DESTINATION_NUMBER',
        'message': 'MESSAGE',
        'dlr': true
    }, function(err, smsId, retPduObj) {
        if (err) {
            throw err;
        }

        console.log('SMS sent, smsId(s): ' + smsId.join(', '));
        console.log('Return PDU object:');
        console.log(retPduObj);
    });

    clientSession.on('dlr', function(dlr, dlrPduObj) {
        console.log('DLR received:');
        console.log(dlr);

        console.log('DLR PDU object:');
        console.log(dlrPduObj);

        // Gracefully close connection
        clientSession.unbind();
    });
});

Thank you a lot for the bug report!

Would it be possible to get the detailed log (the exact PDUs sent back and forth) so I can recreate the issue? It is pretty easy to obtain very detailed logging if you alter the Winston Console log level to "debug" or even better "silly" (that is VERY verbose though!). Let me know if you need any assistance in setting logging.

There is a test for obtaining DLRs here: https://github.com/larvit/larvitsmpp/blob/master/test/04_session.js#L294

I'd like to improve that to catch the error you're seing.

Thanks for your reply here is the pdu I got back from the smpp server after submit_sm:

[ { params: { message_id: 'MESSAGE_ID' },
    tlvs: {},
    isResp: [Function],
    cmdLength: 36,
    cmdId: CMD_ID,
    cmdStatus: 'ESME_ROK',
    seqNr: 2,
    cmdName: 'submit_sm_resp' } ]

Hm. I've added a test specifically for this example. See https://github.com/larvit/larvitsmpp/commit/1e2529409503b6ddaa56b9b4623fd9ac2a2138ba

I can not find anything wrong, so I guess it is a difference in the PDU sent from the remote server (in the test I'm using the same library to test against).

If you could please submit a full log output of a test run with your code? You can fetch that log from the console by adding this code before your code:

var log = require('winston');

log.remove(log.transports.Console);
log.add(log.transports.Console, {
    'level': 'silly',
    'colorize':  true,
    'timestamp': true,
    'json': false
});

IMPORTANT!!! Make sure to strip sensitive data from the output!!!

I'm closing this for now. Please feel free to open it again if I can get some code/log to reproduce the behaviour.

Hello, I have experienced this issue, the upstream server from me is http://www.ozekisms.com/

I have removed sensitive information.
