Further information: I used the original [DataCodings.Default], but encoded the message using my own GSMEncode function and passed the bytes to [SmppClient.PrepareSubmit], the received message correctly displayed the ? character as well as all the other characters - could this character have been mi...

Using:
MapEncoding(DataCodings.Default, System.Text.Encoding.Default)

The message received at the handset is now missing the following characters:
[]{}^|\:

(the question mark was displayed though!)

Hi Alt, (Using Inetlab.SMPP v1.0.11.1) I am using the coding [DataCodings.Default] within [SmppClient.PrepareSubmit] to send the following message: TEST []{}?@'-_!£$%^&*()_-=+,./<>|\àèïôû TEST The handset receives: TEST []{}@'-_!£$%^&*()_-=+,./<>|\àèïôû TEST It is missing the ? character. Could this...

Hi Alexey I have found a couple of issues with [Receipt.cs] Parse(string text) doesn't catch 'ENROUTE'. Also, I use the provider mBlox who returns 'ACKED' as a status, which I guess is another 'ENROUTE' designation. Frustratingly, when accessing the whole receipt you rebuild it using the items you'v...

Absolutely yes, SMSC's recommend you maintain an open connection and get upset when you attempt to bind for every message send. EnquireLink was designed to keep a small conversation going between you and the provider so you're both aware whether a connection is still valid or not.

Hi Ash, You can specify an Alphanumeric SrcAddr. When you call SubmitSm make sure you set: SrcTon = Enum_TON.Alphanumeric '(enum definition below) Be aware that the networks support a maximum length of 11 characters for this, depending on your SMSC it will either return an error if you try to use a ...

Any question you may have about implementation has probably already been asked and answered on this board. As Alt says, you get the entire source code for the SMPP library after you pay for the license, even if you don't like the product after purchase the fee is well worth it to view some excellent...

Is this some kind of synchronization issue ? Deadlock ? I'd have to say yes, as I haven't experienced the behaviour you mention. How much work are you doing in the events? To ensure stability under severe load I adopted the following within my code: 1) Do not perform any work directly on the receiv...

None of the providers I use insist on a VPN, the only security in place for the connection is a restriction on which IP address I am allowed to bind from.

Can't find Telecom NZ SMPP, all I keep finding is Routo Messaging, is this the provider they use for the SMPP?

Looks like you tried the obvious then, can't think of anything else to try All I can say is I'm successfully using it with mBlox, Hays, Sybase and AQL - what provider are you using? If they offer a trial account I'm more than happy to try and connect to it and see what response I get from it.

Is your Linux based app currently bound when you attempt to bind via this component? Does the troublesome telco support SMPP v3.4? I had trouble binding with one of my providers and it turned out to be my IP address wasn't on the allow list for the SMPP server I was binding to - get your provider to...

Hi, Are you running your application as a windows form, and have you placed any initialisation code in the form load/startup events within the form that may start communicating with SMPP *BEFORE* the form is fully loaded? If so, I would recommend you pull the code from the form startup events and pl...

Hi Racheliya,

This is a forum specifically for information relating to the ALT.SMS.SmppClient class library.

That said, try this link for a resource which may help you http://www.filesaveas.com/gprsconnect.html

Found the cause:

Within [DeliverSm.vb], [Public Sub New()], you need to add [_user_data = New UserData()] for the serialization to work.

Hi

DeliverSm reports "Object reference not set to an instance of an object" whenever an attempt is made to serialize it. (v2.6.0.0)
