Hi Ishmel, Is it possible that the last parameter you use for .PrepareSubmit could be Nothing/Null? The SMPP component may well be handling the exceptions internally and seeing null it then passes a null out which will then freak out the assignment [oRespList = ] meaning the SMPP exception will not ...

Hi Major, I only use the async method - Maximum throughput I have attained connected to 'mBlox' is ~250 message parts per second per server, mBlox provide connection to two servers simultaneously so the best I have managed is ~500 message parts per second spread over two 'mBlox' servers communicatin...

Hi Major, I only use the ASYNC methods myself (for speed). 1) I prepare my message to send using InetLab, this splits the message into 1 or more parts that are required. 2) I store the 1 or more parts in a 'messagesend' sql table, and use the unique record id of each message to set the 'sequence num...

Hi Major The ESME_RTHROTTLED is returned with the Message Id and Sequence number. When you send any message you always receive a unique identifier (Message Id) from the SMSC, you need to store this alongside the message in your (sql table? - I use the unique id of each message record as the sequence...

Hi

You will have to implement your own throttling code. Keep a counter going that resets every 1 second, if the counter > 20 then pause 10ms and check again.

Cheers

Ask the SMSC which PDU they return that contains the Throttle Response. The SMPP v3.4 Specification says this: The command_status field of an SMPP message response indicates the success or failure of an SMPP request. It is relevant only in the SMPP response message and should be set to NULL in SMPP ...

Works perfectly now, many thanks.

Hi Alexey,

Further information:

The error still occurs even when I don't do any work in the SmppServer events - it happens after receiving 10000+ submissions which have been sent at around 400 per second. It isn't related to me sending the same client DeliverSm's.

Regards

Nick

Hi Alt, I am receiving the exception below when I am stress testing the SMPP Server component. I am receiving approximately 250 SubmitSm's per second from a single ESME, and delivering DeliverSm's back to it using SmppServerClient.Deliver within another thread at approximately the same rate. System....

Hi MajorTargets, Do you check the command_status of the returned SubmitSmResp? I have noticed one of our providers simply drop the DeliverSm if I attempt to send more messages to them per second than is in our contract - They should send back a throttle response but this provider doesn't support it....

Hi Shazia1, You need to determine before you send the message whether it requires a unicode character set or whether the characters used could be sent via GSM character set. Arabic would need to be UCS2, which allows you to send 70 symbols at a time, so a message using 150 Arabic characters would ta...

I downloaded v1.0.12.2 and it has fixed the problem, so no investigation required - thanks!

Hi Alt, Inetlab.SMPP v1.0.11.3 I can't serialize a DeliverSm, it keeps throwing an exception, the stack trace is as follows: StackTrace " at Inetlab.SMPP.PDU.DeliverSm.WddAOCwt0e() at Inetlab.SMPP.PDU.DeliverSm.GetBytes() at Inetlab.SMPP.PDU.DeliverSm.Serialize(DeliverSm deliver) at tms.SmscProcesso...

v1.0.11.3 has fixed the issue, many thanks for such a quick turnaround

RE: Intelisense
I am using the compiled library v1.0.11.1 and Intellisense is working fine for me in Visual Studio 2008 and Visual Studio 2010.
