ERROR when using the downloaded code as a transceiver

[rana]

I am using the SMPPCLIENT as a transceiver. In the client_evDeliverSm function I am trying to send back and send back a response to the sender. When running application the following behavior is found:
• A message is received.
• It is correctly processed.
• When trying to send back a reply the error found is SMPPCLIENT_RCVTIMEOUT.
• The message will be sent over and over although it is being submitted successfully from the first time.
• No messages are being received anymore.

i have looked for SMPPCLIENT_RCVTIMEOUT in the SMPP protocol description but i havent found it yet. can anyone please tell me why am i having this error? and can it be caused by the fact that i havent bought the code and that i am only changing a downloaded version?

Code: Select all

Please try event evDeliverSmComplete. It is raised when DeliverSmResp already sent.

In the event evDeliverSm you can modify DeliverSmResp response. f.i. send non OK status.
