we are still not confident about the v2 so we cannot go live with it right now and test it.

What is the reason of it? Do you mean the issue with corrupted SMPP stream from remote side?


Hi alt, The main reason is the stability of the v2 version. I don't know what happens but when v2 is put ...

I have improved delivery receipt parsing. Library tries to work around this issue when ASCII text can be decoded. Please test latest 2.9-beta from today.


Thanks for the update in v2. but we are still not confident about the v2 so we cannot go live with it right now and test it. can you please ...

Do you see any warnings or error in the library log with V1?
The reading from network is very simple: Each SMPP PDU begins with 4 bytes of the length with following bytes of data. Library uses synchronous reading in one thread for a SMPP session, so multi-thread issues are impossible. If remote ...

Hi alt,

I think the SMPP stream from provider was corrupted. In some point of time it starts to send inconsistent data. The library detects this situation and drops the connection. I would suggest to analyze SMPP traffic with Wireshark.

There is no issue while sending a batch of 120000 Messages ...

Hi alt,

Almost everything is working fine in the upgrade to v2 only some few errors are showing in log occasionally. If you can please assist us why these errors are coming.

1. Event evFullMessageReceived failed Exception: System.ArgumentNullException: Array cannot be null. Parameter name: bytes ...

The number of requests waiting for response you can read from metric: client.Metrics.Sent.Requests.WaitingForResponse i tried this it always shows 0 or 1. but my problem is i have submitted batch containing 50 messages.

IEnumerable<SubmitSmResp> ResponseList = (await SMPPClient.SubmitAsync(batch ...

please suggest a value for SendQueueLimit if normally batch submission is around 15k-25k to avoid ESME_RMSGQFUL. And shouldn't send speed limit should delay the message sending regardless how many are begin fed in queue.

So alt how we can get the count of messages that is inside the library for which pdu has not been sent.

And we are also getting esme_rmsgqful when we submitted in bulk with submitspeed of 240 any solution for this.

hi alt,

The Sent Queue always shows as 0. I have set speed of 1mps and sent 1500 messages but the queue always return 0.

Latest beta library version.

see log dump.

Thanks alt we have done the same way implemented dictionary.

Hi Alt,

1. An exception was thrown by a TaskScheduler.
2. Value cannot be null. Parameter name: scheduler
I do not have the stack trace for these errors but we have no issue with v1 of your library all vendors connect just fine. we tried to work with v2 of your library when it was just launched ...

Hi ,

while connecting to vendor some of the vendors we are getting this error.

An exception was thrown by a TaskScheduler.

code snippet.

bool bSuccess = await SMPPClient.ConnectAsync(VendorAccount.Host, Port);
if (bSuccess)
{
WindowsLogger.WriteSMPPCriticalLog(VendorAccount.VendorAccountID ...

Hi Alt,

the event client_evDeliverSm starts firing before the submitasync has given process all the messages.

IEnumerable<SubmitSmResp> ResponseList = (await SMPPClient.SubmitAsync(batch)).ToArray();
before ResponseList is populated with responses client_evDeliverSm starts firing this creates a ...

Hi,

byte srcTon = byte.Parse("0");
byte srcNpi = byte.Parse("0");

Hi,

we are setting the tag property like this

ISubmitSmBuilder builder = SMS.ForSubmit()
.Text(messageText)
.From(sourceAddress)
.To(destinationAddress)
.Coding(coding)
.Set(s => s.Tag = 23);

batch.AddRange(builder.Create(SMPPClient));

but tag always return null in
