Subject: Matrix Mobile 1.3.1.1
I have been using v1.2.1.1 for some time - and it worked more or less reliably, but few days ago I've downloaded 1.3.1.1 and that suddenly stopped working!

What I saw is that regardless of StartTls or KeepAliveInterval values it always threw SocketException and also NullReferenceException in Matrix.dll and then finally arrived to OnError() handler.

Is this a known issue or I'm missing something simple?

BR,

Hi, Alex,

I've double checked and cleaned all I only could think of, and now it's not throwing SocketException anymore, but the following (see below). I should probably mention I run it on WinCE 5.0. It happens with and without StartTls = true.

Xmpp Debug output:

The exception (I checked CRL Exceptions and Managed Debugging Assistant in Debug->Exceptions):

In this log you have StartTls = true, MatriX negotiates TLS and there seems to be a TLS problem. Try without Tls.

BTW i uploaded a new Mobile version some minutes ago which I have successfully tested on my jabber.org account with and without Tls. But I tested on on WM6 pro.

Hello Alex,

sorry for the delay with the answer - I was dragged to something else as usual and couldn't check new versions.

From what I see now, I've tried both 1.3.1.0 versions available as 'stable build' and 'development build'. In both cases I see that there is some IOException in Crypto.dll and then ObjectDisposed exception. Hence it never manages to connect.

v1.2.1.0 works though :) On few occasions I've got NullReferenceException in OnError() handler (ie it was called with such exception as a parameter), but I cannot put my finger on something specific - it was connected for some time and then disconnected and never reconnected back.

I'm using some custom device with WinCE 5.0, so I wouldn't be surprised if it lacks some dlls/API, but it would be really nice if 1.3.1.0 can work on it.

BR,
Alex

1.2.1.0 was without TLS support using the crypto library. It was using native TLS which was causing problems on reconnect.
Can you please try without TLS (StartTls = false)?

Are there emulator images for VS2008 for WinCE 5.0?

There are no emulators for WinCE and VS2008, Microsoft has long abandoned it :(

Re. new matrix.dll version. I have tried with StartTls = false;

I drives me crazy :) because I see in the log that regardless of what I set in the code, it logs the following:


[10/27/2009 12:45:11 PM] DEBUG: SEND: <stream:stream xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client" to="jabber.org" version="1.0" >

General pattern is that it arrives to OnCLose() first, then to OnError() with something like that:

[10/27/2009 3:51:44 PM] DEBUG: xmppClient.OnClose()
[10/27/2009 3:51:44 PM] DEBUG: CreateReconnectTimer: reconnectAttempt=0

   at Matrix.XmppStream.?(String ?)
   at Matrix.XmppStream.?(String ?)
   at Matrix.XmppStream.?(Object ?)
   at System.Threading.Timer.ring()

I'll happily try whatever you think is worth :)

sorry but I cannot cause your problem. When StartTls is false then it use no Tls here.
I uploaded a new build to:
http://www.ag-software.net/downloads.html
Please make sure that you use this build and StartTls is false.

whoo hoo, it connects :)

found finally a piece of code that set StartTls to true (a leftover from earlier tests), so now it works without Tls. Phew!

Thanks a lot for your patience and help.
