Where DO I Need To Set Short Code

[HemanParbhakar]

Can You Please Help me Where we need to set short code

[ritmas]

I believe you have in mind sender value which is set as source_addr:

session.submit_sm({
destination_addr: '<phone_number>',
source_addr: '<sender/shortcode>',
short_message: '<SMS_body>'
});

[HemanParbhakar]

var smpp = require('smpp');
var server = smpp.createServer(function(session) {
session.on('bind_transceiver', function(pdu) {
// we pause the session to prevent further incoming pdu events,
// untill we authorize the session with some async operation.
session.pause();
checkAsyncUserPass(pdu.system_id, pdu.password, function(err) {
if (err) {
session.send(pdu.response({
command_status: smpp.ESME_RBINDFAIL
}));
session.close();
return;
}
session.send(pdu.response());
session.resume();
});
});
});
server.listen(2775);

// Using This to create server please Hellp

Getting Error Of checkAsyncUserPass is not defined

[ritmas]

It's not clear in this code snippet whether you have defined such function checkAsyncUserPass

[HemanParbhakar]

i have copy this fuction from README and there was exact the same

[ritmas]

This example is quite old and misleading. My suggestion is not to use checkAsyncUserPass() and do your own actions as successful bind_transceiver callback is all what you need - once it's fired up, you may send/receive messages.

[HemanParbhakar]

ok Thankss And Can Transeceiver set to be multiple Connection at same time

[ritmas]

Well transceiver mode is dedicated for bidirectional communication, which means the same session supports both transmitter (sending messages) & receiver (receiving messages) modes. In other words, you don't have to initiate two connections at the same time to fully support communication with SMSC.

It's enough to maintain single session with SMSC for sending multiple messages and handling received ones at the same time. But if you want to handle multiple sessions to the same SMSC make sure SMSC configuration allows you to do that. In most cases, it should be restricted to 1-2 sessions only with different TPS, etc.

[HemanParbhakar]

as My Connection is always open using node server.js . But At Same TIme How Can I Send Message

[ritmas]

It's given in README as an example, you need to use session.submit_sm();

[HemanParbhakar]

but the sms number and message are dynamic as it would be send by android
how can i send SMS then

[HemanParbhakar]

When I Get message Id that means Message has been Sent

[ritmas]

Not really. It means SMSC has accepted your request to send message. Later SMSC will notify you whether SMS has been successfully sent to user or not - that's delivery report. You should handle it upon received PDU with:

session.on('deliver_sm', function(pdu) {
   // parse/handle PDU
   session.send(pdu.response());
});

PDU example of deliveyr report is:

{
    command_length: 144,
    command_id: 5,
    command_status: 0,
    sequence_number: 33576672,
    command: 'deliver_sm',
    service_type: '',
    source_addr_ton: 1,
    source_addr_npi: 1,
    source_addr: '<phone>',
    dest_addr_ton: 2,
    dest_addr_npi: 1,
    destination_addr: '<schortcode>',
    esm_class: 4,
    protocol_id: 0,
    priority_flag: 0,
    schedule_delivery_time: '',
    validity_period: '',
    registered_delivery: 0,
    replace_if_present_flag: 0,
    data_coding: 0,
    sm_default_msg_id: 0,
    short_message: {
        message:'id:37bc0c3 sub:001 dlvrd:000 submit date:1705190504 done date:1705190504 stat:DELIVRD err:000'
    }
}

Here stat:DELIVRD indicates SMS has successfully reached destination.

[HemanParbhakar]

Means i have to Implement this on Reciever

[MukitCSTE]

How to send

SMSC --> ESME

i mean can i work like this

session.deliver_sm({
command_length: 144,
command_id: 5,
command_status: 0,
sequence_number: 33576672,
command: 'deliver_sm',
service_type: '',
source_addr_ton: 1,
source_addr_npi: 1,
source_addr: 'Custom SMPP Service',
dest_addr_ton: 2,
dest_addr_npi: 1,
destination_addr: 'Client',
esm_class: 4,
protocol_id: 0,
priority_flag: 0,
schedule_delivery_time: '',
validity_period: '',
registered_delivery: 0,
replace_if_present_flag: 0,
data_coding: 0,
sm_default_msg_id: 0,
short_message: {
message:'id:123 sub:001 dlvrd:000 submit date:1705190504 done date:1705190504 stat:DELIVRD err:000'
}
}, function(pdu) {
if (pdu.command_status == 0) {
// Message successfully sent

			console.log('The Delivary report  is  successfully sent');
		}
	});

[MukitCSTE]

session.deliver_sm it's working finally . Thanks to all :)

So, how can i does cuz i have this error :

checkAsyncUserPass('wavesmpp1', 'wavesmp1', function(err) {
^

The checkAsyncUserPass is not defined for me.
Please i need a help !

[ritmas]

checkAsyncUserPass() is custom function, you can define it by yourself:

function checkAsyncUserPass(system_id, password, callback) {
    if (system_id === 'wavesmpp1' && password === 'wavesmp1') {
        callback(0); // no error
    } else {
        callback(1); // error
    }
}

    } else {
        callback(1); // error

}

Ok, thanks. But now i gat the error like :

Error: Cannot find module 'smpp'

[ritmas]

function checkAsyncUserPass(pdu.system_id, pdu.password, function(err) {

You've defined function parameters as pdu object properties, but I assume you're passing them as variables. Double check on the code itself on how you're calling checkAsyncUserPass().

The error is : Error: Cannot find module 'smpp'

Please how can i fixe it ?

[Kindlysertir]

I install smpp like : npm install smpp it work. Thanks !

[Kindlysertir]

But i can not connect to it.

[juliangut]

@Kindlysertir have you required the module in the code?

var smpp = require('smpp');

[juliangut]

It's been almost 3 months since last answer, I assume we can close this issue. Feel free to comment again if needed
