Is CUAP based on SMPP protocol?

Hi jeremih

You cannot add optional TLV parameters to the Bind request, the SMPP protocol doesn't support this.

Why do you want to add the headers ?

Hi,

USSD over SMPP is always vendor specific implementation. Try to start with the sample USSD project.

It is already released. See the change log.

Please try to force the thread pool to create more worker threads

Code: Select all

ThreadPool.SetMinThreads(200, 200);

ok. submit speed 0 is the same as NoLimit in the SmppClientDemo.

Unfortunately I cannot reproduce this issue with latest version. Could you help me?
What server are you connecting? Can you reproduce this issue with SmppServerDemo?

Hello ritik,

When you set 0 for SendSpeedLimit property, do you want to disable this limit?
Have you tried LimitRate.NoLimit value?

I'll try to reproduce this case and let you know about results.

What library version do you use?

for example:

Code: Select all

_client.EncodingMapper.AddressEncoding = Encoding.ASCII;

If SmppClient instance is not subscribed to evDeliverSm event the ESME_RINVCMDID will be returned. If the handler of the event evDeliverSm is failed the ESME_RSYSERR will be returned and the error is written into the library log You can always use try catch in the event handler method to handle the ...

The smpp session will be dropped when unsuccess response status in EnquireLink is received. In your case the server could be busy with your messages and the EnquireLinkResp is sent later than 19 seconds. The library already processed the timeout and returned the SMPPCLIENT_RCVTIMEOUT. The detailed l...

What value have you set for the property ResponseTimeout in SmppClient instance?

The EnquireLink PDU is sent only in idle time. It means it will be sent in 20 seconds after last received PDU from the remote side.

Could you provide more detailed logs?

Hi aordonez,

What library version are you using?

Yes, you can deny the connections. You need to check client.RemoteEndPoint in the evClientConnected event.

This code can help you to get the MessageId from the TLV parameters.

Code: Select all

 
 var parameter = deliverSm.Parameters.Of<ReceiptedMessageIdParameter>().FirstOrDefault();
 string messageId =  parameter.MessageId;

There no way to get the MasterSecret from the .NET SslStream.

You can enable verbose logging for the library and find "Received data:" records with received PDUs in hex format.

The data can be decoded on the website https://www.sysop.fr/smpp-decoder/
