Hi I am using JamaaSMPP from last few week I integrated this library with DB and it working fine on local machine , first I connect to client and send sms asynchronously ,I have written asyc and wait method which run every after 10 second and send sms with success.
But while hosting this on server I am getting pdu send and receive time out error.
also getting very less TFS on server I have AWS 64 bit windows server with 8 GB ram

Kindly help

Hi Adham,
I've been using JamaaSmpp for the past nine months and lately, we've encountered a very abnormal problem. When sending large messages(more than 2 PDUs) asynchronously using BeginSendMessage, sometimes the messages get merged and the user gets only one message which is a combination of the two sent messages. The final message has the exact number of characters of one of the messages but the content is neither one of them.
P.S: It's worth mentioning that I send nearly 500 PDUs every second in rush hours.
I appreciate it if you can help me with this issue. Many thanks.

Hello,

When I send Arabic text, I receive some sort of Chinese letters in mobile, I have tried it with all different Encoding types it has and with every Encoding I have received some strange letters and not the Arabic text I intended to send.

Hi, would like to ask for some help. I am pretty new to SMPP is it possible to send a message that is longer that 160 Character. I've been trying to read through the Wiki but can't seem to find articles/documents regarding this. Any help is appreciated. Thanks.

Hello Adham,

Is it possible to bind only as Transmitter or Receiver? I know it is possible to bind using separate connections by using version 3.4 but that way it creates two separate connections at the same time. In my case I have two separate hosts for transmitter and receiver. In order to handle this I extended SmppClass like this, which forced me to change some fields to protected:

    public class PJSmppClient : SmppClient
    {
	private ClientType type;

	public PJSmppClient(ClientType type) : base()
	{
		this.type = type;
	}

	protected override void OpenSession(SessionBindInfo bindInfo, bool useSeparateConnections, int timeOut)
	{
		ChangeState(SmppConnectionState.Connecting);

		if (type == ClientType.Receiver)
		{
			//
		}
		else
		{
			//
		}
		ChangeState(SmppConnectionState.Connected);
	}
}

public enum ClientType
{
	Transmitter,
	Receiver
}

It seems like the Nuget package is quite out of date?

Any chance it can be updated to the latest version?

Hi Adham,

I am sending acknowledgement of receipt of message delivery notification using following code, inside client_MessageDelivered event:

PDUHeader header = new PDUHeader(CommandType.DeliverSmResp, seqNumber, SmppErrorCode.ESME_ROK, (uint)seqNumber.ToString().Length);
DeliverSm ackPDU = new DeliverSm(header, client.SmppEncodingService);
var resp = client.SendPdu(ackPDU, 0);

But I am getting thread aborted error at client.SendPdu(ackPDU, 0);

Following is the stack trace, please let me know if i am doing it all wrong or what:

Hi,
I am facing issue while i am trying to send a long message using async feature.
I am able to send same long message using sync feature.
Please find the following code for your reference.
Please help. I am stuck.

Hi,

I'm trying to send an SMS to an international (+44) number (we're in South Africa), according to the logs we're getting a SmppException with an ErrorCode property that reports a 'ToString()' value of 1024. This is obviously not in the Enum for SmppErrorCode.

Any Ideas?

Hello, receive a cordial greeting.

Implemented a smpp client as shown below:

public static SmppClient GetSmppClient()
{
    var client = new SmppClient();

    SmppConnectionProperties properties = client.Properties;
    properties.SystemID = "MyID";
    properties.Password = "MyPassword";
    properties.Port = 1234;
    properties.Host = "MyHost";
    properties.SystemType = "smpp";
    properties.DefaultServiceType = "smpp";
    properties.SourceAddress = "6015";
    properties.InterfaceVersion = InterfaceVersion.v34;
    properties.DefaultEncoding = DataCoding.SMSCDefault;
    properties.AddressNpi = NumberingPlanIndicator.ISDN;
    properties.AddressTon = TypeOfNumber.International;

    client.AutoReconnectDelay = 30000;
    client.KeepAliveInterval = 15000;

    return client;
}

private void listenMessageReceived()
{
    client = GetSmppClient();
    client.ConnectionStateChanged += connectionStateChanged;

    if (!client.Started)
    {
        client.ForceConnect();
        client.Start();
    }

    client.MessageReceived += messageReceived;
}

private void messageReceived(object sender, MessageEventArgs e)
{
    TextMessage msg = e.ShortMessage as TextMessage;
    SetSMSDataGridView(DateTime.Now, msg.SourceAddress, msg.DestinationAddress, msg.Text);
}

public void SetSMSDataGridView(DateTime date, string sourceAddress, string destinationAddress, string text)
{
    this.dgvSMS.Rows.Insert(0, date, sourceAddress, destinationAddress, text);
}

The problem is that when I run multiple instances of my program, all SMS are not received in all instances.

As you can see below:

Both instances of the program are running at the same time, but the SMS they receive are different.

Thanks for your help.

I am using Jamaa Library 1.5.3 and using below code for sending SMS
TextMessage msg = new TextMessage
{
DestinationAddress = smsDetails.ToMobile,
SourceAddress = smppConfig.SourceAddress,
Text = smsDetails.Message,
RegisterDeliveryNotification = true,
//UserMessageReference = smsDetails.RequestId.ToString()
};
clientSMPP.SendMessage(msg);

Here I commented UserMessageReference as Service Provider doesn't support TLV ...When we send few Messages , SMS getting delivered successfully but when we send messages continuously around 10 nos./sec, Service Provider receives below error ....
Invalid parameter length:[105] max:[20] safe_value:[ABC FAILURE ALERT(Ge] '
Invalid parameter length:[102] max:[16] safe_value:[ FAILURE ALERT(G]

Kindly let me know what could be reason for this error ...................

[Typo] TypeOfNumber should be Alphanumeric instead of Aphanumeric

JamaaTech.Smpp.Net.Lib.TypeOfNumber enum has a value (5) named Aphanumeric, it's a typo and it should be Alphanumeric instead.

Hi Adham,

the source address that I use which is 2345 appears in international number format with a '+' prefix when SMS is received on the mobile phone i.e as +2345. I want the source address(sender) to appear as 2345 only, without the '+' sign. What should I do?

Line 55: client.SendMessage(msg);

What are the proper Encoding to get Arabic messages correctly? Because I tried ASCII, SMSCDefault, Latin_Hebrew and UCS2 are not working well, it always appears like "????????".

Hello Adham,

I came across a strange behaviour in JamaaSMPP.
According to the SMPP 3.4 spec, the user_message_reference TLV can only be 2 bytes long:
http://docs.nimta.com/SMPP_v3_4_Issue1_2.pdf

However, JamaaSMPP allows a string of arbitrary length to be passed and also adds an extra zero byte at the end:
https://github.com/AdhamAwadhi/JamaaSMPP/blob/master/JamaaTech.Smpp.Net.Client/TextMessage.cs#L70

My provider does not accept such a message and throws the ESME_RINVPARLEN error.
Sending a message using only a single byte ID works as expected, but this is a hack and cannot be deployed to production.

Why does it work like that? Is there any fix or a workaround?

Hello.

We want to know how to use USSD app with this Easy SMPP project ???

Please help us.

Can you paste an example of concatenated SMS? because I'm receiving 2 or 3 separated messages.

For all the segments of an SMS longer than 140 chars, the sequence number is the same.
It should not be.
For some SMSC, the connection is rejected and re-binded and the SMS is not fully sent.
It could give an Null Exception ins some case.

I forked the project to make fix the bug, do you want me to create a pull request ?

Do you have sample code that combine the UDH message/concatenated message in submit_sm.

When the message is longer and the library split the message.
The speed at which consecutive parts are sent is so high that server limitations jump.
I have temporarily fixed it by putting a delay of 100ms between each part send.

SmppClient - SendMessage

` foreach (SendSmPDU pdu in message.GetMessagePDUs(vProperties.DefaultEncoding, vSmppEncodingService))

        {
            ResponsePDU resp = SendPdu(pdu, timeOut);
            var submitSmResp = resp as SubmitSmResp;
            if (submitSmResp != null)
            {
                messageId = ((SubmitSmResp)resp).MessageID;
            }
            message.ReceiptedMessageId = messageId;
            RaiseMessageSentEvent(message);
            Thread.Sleep(100);
        }`

Is there another solution to this problem?

Hi,

I'm trying to send a SMS with more than 160 characters, but it doesn't work properly when I test the message below:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla ut commodo lorem, eget molestie velit. Etiam mollis ex ac dignissim pharetra.

Return:

mauris semper, dapibus erat sed, tempus sapien. Proin sem dui, elementum sed convallis non, porttitor quis nisl. Mauris id eros vestibulum, bibendum dia

As we can see, I received it in the following order: 4 - 3 - 1 - 2.

I already read about payload parameters in another NuGet packages, but I didn't found anything about this in JamaaSMPP documentation yet.

Is there a parameter that I can use to send this SMS in the correct order? Is there a way to send it in only one SMS?

My code:

    Private Sub btnConectar_Click(sender As Object, e As EventArgs) Handles btnConectar.Click

        Dim msg As TextMessage = New TextMessage()
        msg.DestinationAddress = "5511981000000"
        msg.SourceAddress = "5511981000000"
        msg.Text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla ut commodo lorem, eget molestie velit. Etiam mollis ex ac dignissim pharetra.

        msg.RegisterDeliveryNotification = True

        Dim client As SmppClient = New SmppClient()

        Dim properties As SmppConnectionProperties = client.Properties
        properties.Host = "40.200.199.1"
        properties.Port = 9500
        properties.SystemID = "user"
        properties.Password = "pass"
        properties.SystemType = ""
        properties.DefaultServiceType = "CMT"
        client.AutoReconnectDelay = 3000
        client.KeepAliveInterval = 15000
        client.Start()

        If client.ConnectionState <> SmppConnectionState.Connected Then client.ForceConnect(5000)

        Try
            client.SendMessage(msg, 15000)
            MessageBox.Show("Return: " & msg.ReceiptedMessageId)
        Catch ex As Exception
            txtResult.Text = ex.Message
        End Try

    End Sub

Hi Adham,

I have created following acknowledgement which needs to be sent from my ESME to the SMSC.

var encSrv = new SmppEncodingService();
PDUHeader pduheader = new PDUHeader(CommandType.DeliverSmResp, (uint)e.ShortMessage.SequenceNumber, SmppErrorCode.ESME_ROK);
var pdu = PDU.CreatePDU(pduheader, encSrv);

Can you please tell me how can I send this pdu from my ESME to the SMSC now.

Thanks,
Poonam

We are using your JamaaSMPP library in one of our projects and it is really useful and helpful. Could you please clarify the below query?

1. Does the library supports bulk SMS, meaning can we send multiple mobile numbers at the same time with some delimiter?
2. If yes, could you please let us know how this can be achieved.

When we try to send the list of mobile numbers, we get below Error code

at JamaaTech.Smpp.Net.Client.SmppClient.SendPdu(RequestPDU pdu, Int32 timeout) in D:\Work\My\JamaaSMPP\JamaaTech.Smpp.Net.Client\SmppClient.cs:line 218
at JamaaTech.Smpp.Net.Client.SmppClient.SendMessage(ShortMessage message, Int32 timeOut) in D:\Work\My\JamaaSMPP\JamaaTech.Smpp.Net.Client\SmppClient.cs:line 19
and smppEx.ErrorCode - 1078

Sasanka M

We get multiple improper message at mobile while sending long message. As if UDH is sent the ESMClass is not set properly. Its 0x40 but in SMPP v34 definition it shows 7th bit to be 1 i.e. 0x64. correct me if i am wrong. Even changing the values, i get no luck.

When the Encoding value is set to UCS2 and the message is more than 70 characters, it uses a fixed value of 67 to split the messages. How can I set my default value? Actually, my values are different from the default value.

I am using this library from last one year but in SYNC mode only. but now to increase sending speed i now using aync mode for message sending and it works normally. but when there are large push to send then suddenly start getting ESME_RINVBNDSTS exception and then it close the session. and because of this my many messages where droppped or getting multiple client_MessageSent event called. I have almost tried to solve it from last 4 days but still not resolved. For your reference i am connecting provider by Transceiver.

Please,

is there any plans in near future for .NET Core version of JamaaSMPP?

Thanks

Some providers require the Source Address Type of Number Specified.
This is in case you are sending an SMS from an Alphanumeric source address:

I was hopping that this could be included in SmppConnectionProperties

SmppConnectionProperties

Right now we get an exception from our provider (MTN Swaziland) if we do not specify the Source Address Type of Number for Alphanumeric source addresses.

I am facing another issue now. I am getting sent and delivered events fired for same sms multiple times.
How can I stop that? How to tell the server that i have got it and please stop duplicating now.

Please help.

Thanks a lot,
Poonam

When a bind fails to connect, the isn't much information given by the library. It would be nice if more information about the failure reason could be included in connection state changed event.

The SMPP Service we use allows not setting the Source Address on the message and they use the default attached to the account.

I have confirmed this works using another SMPP Client Demo program

When I try to do the same, I get an Invalid Source Address error

Exception of type 'JamaaTech.Smpp.Net.Lib.SmppException' was thrown.

Error Code is : ESME_RINVSRCADR

If I replace the source address with the Mobile number, it works perfectly.

Below is the code to create the message.

TextMessage msg = new TextMessage();
msg.DestinationAddress = mobileNumber;
msg.SourceAddress = "";
//msg.SourceAddress = "Entering Number Here works fine";
msg.Text = call.LongMessage;
msg.RegisterDeliveryNotification = false;

is there a reason why the exception is being thrown when no source?

Thanks,
Daniel.

Hi,

Please provide me an example for creating DeliverSmResp or Deliver_Sm_Resp and sending it to the server as a response.

Thanks,
Poonam

As per new govt norms we need to pass new two TLV parameter in submit_sm request, can any one help me to do it.
I have attached this parameter here.

Hi,

The variable UserMessageReferenceType seems to be missing in the JamaaTech library. How do I solve this?

Regards

I have set registerdeliverynotification = true and attached messagedlvred event handler. But not event fired,

Does client.start() keeps on checking deliversm pdu or thers something i m missing.

Hosted SMppClient on static variable in .net web application and calling sendmessage asychronously, even 500 msgs get sent and those received on mobile but no delivery event is fired.

Hi,
If you enter the wrong SMPP details or there are continual connection issues, eventually (usually within 10 minutes) you get an exception that crashes the entire application (no just the SMPP client) as we have everything wrapped around a Try / Catch Block and the exception does not get thrown back to the calling method.

We have an issue with a carrier who isn't using the standard sm_length and short_message parameters, instead opting to put message data in the optional TLV parameter message_payload.

Is there a standard way to access the received PDU to get the optional parameter? PduReceivedEventHander is not overridable.

Whenever I set the UserMessageReference I receive an Invalid Parameter Length exception. It doesn't matter which version of the library I am using or which telecom operator I am connecting to. I have tried this with 3 telecom operators and in all of them I receive this error. I also tried to change the format of the UserMessageReference but It also doesn't make any difference.
