MatD's Symbian pages
The first time I began to develop with Symbian I was lost... What is a mmp File ? How to produce a SIS ? Where can I see if my development workspace is correct ? Having found the answers to all these questions and other tricky problems, I decided to write little articles about Symbian development.
Nokia 3230 and gnuBox (posted 06/10/05 by MatD) Updated: 06.01.2008
Browsing for free through the Internet with a Nokia 3230 thanks Bluetooth is the main feature of a freeware called gnuBox. Learn how to configure your PC and your Nokia 3230 with the following tutorial. Translation in French and German will follow

Update : 06.01.2008 "Where is the mRouterDeveloper ?" issue

Many visitors were asking where the famous mRouterDeveloper Edition could be found. If you googled the name of Intuwave or mRouterDeveloper you have discovered that the entreprise doesn't exist anymore.
As this is very annoying for Symbian developers, I'm giving you the opportunity to download this precious file directly from this website. This is the original mRouterDeveloper that came with the UIQ P900 SDK (Year 2004-2005) : http://matdonline.free.fr/mRouterDeveloper.exe

Additionaly you can/should also download the Sony Ericsson PC Suite 3.1.1 for P800-900-910 that contains a version of the mRouter services that are going to be installed on XP and that are used by the mRouterDeveloper. Here is the link of the official site :


or if the link will/is broken : http://matdonline.free.fr/SonyEricssonPCSuite_3.1.1_EN.exe

Please note that you need to rewind the clock of your Windows back to 2000-2004 so that mRouterDeveloper will correctly start. I recommend you to take a look at this other article I wrote ( unfortunately only in German) but the first pics will help you a lot: pdf/P2P Architektur mit mRouter.pdf

N90 Review (posted 12/04/05 by MatD)
This is one of the most funniest mobile phone I ever had in my hand. With a right turn you turn it into a digital camera. The two displays have own integrated functions. This phone is a 3G phone and uses Nokia Series 60 Symbian operating system. Funny stuff is to see that Series 60 older than the Feature Pack 3 are rescaled to adapt to the new screen resolution!

Using the gnuBox with your Symbian C++ program
(posted 10/23/05 by MatD)

Once you have installed the gnuBox (read the related Nokia and gnuBox article) you have certainly noticed that althought you can surf with the browser, you can't use the gnuBox with your C++ Symbian program which is using sockets and network communications. Even by using the correct access point ! Why ? Here is the solution :
This is due to the CCommsDbConnectionPrefTable. This table ( it's a file placed under ) which contains all the configuration necessary for each access point your mobile phone is going to use.

The following operations are dangerous and if not correctly executed may damage your ConnectionTable. If you are using another internet connection than Bt to browse or if you have other "connected" programs, please don't try. BE SURE TO KNOW WHAT YOU ARE GOING TO DO !. This has been tested on a Nokia 3230. On a Nokia 6630 the gnuBox damages the CommDb and you need to format your phone. So please be very very careful and be sure to make a backup of your phone. You have been warned ! If possible use a "test" mobile phone !

First of all we need to extract the CommDb file (gnuBox -> Debug -> Dump Full CommDb) and find out (under C:\Nokia\commdb.txt) which IAP Id is used by the Bt Access Point. In my case the commdb.txt file contained this lines :

Id = 36
Name = Bt
Hidden = FALSE
ReadOnly = FALSE

We now have found which IAP Id the Bt connection is using (Id = 36). We now need to set up our program to use this connection instead of another one. Being fed up to confirm each outgoing connection I've place a


Of course you can change this property in order to let the DialogBox reappear when an outgoing connection is made.

/* Code for unabling IAP Dialog Box and to set up the connection to work with the gnuBox */
RGenericAgent netAgent;

if (netAgent.Open() == KErrNone)

CCommsDatabase* db=CCommsDatabase::NewL();
view = db->OpenConnectionPrefTableViewOnRankLC(ECommDbConnectionDirectionUnknown,1);
CCommsDbConnectionPrefTableView::TCommDbIapConnectionPref pref;

// Gnubox Internet Access Point = 36
// In my case the IAP was : T-Online Internet = 1

pref.iBearer.iIapId = 36;

// Applies the gnuBox IAP for GPRS and CSD
pref.iBearer.iBearerSet = ECommDbBearerGPRS|ECommDbBearerCSD;

// Warns you if a connection is tried to be made view->UpdateDialogPrefL(ECommDbDialogPrefWarn);
TRequestStatus status;
CleanupStack::PopAndDestroy(3); // view, db, netAgent

And voilà ! Now you can use the full communication APIs of Symbian without having to pay your mobile phone communications : everything is going over your computer thanks to Bluetooth and the gnuBox !

R_LIST_QUERY problem (posted 11/17/05 by MatD)

You may have found this kind of error, while desperately trying to compile your program that is including the R_LIST_QUERY ressource. The output message is strange and tells you :

(0) : Link name not found
* RCOMP failed - deleting output files
make[1]: *** [\Symbian\8.1a\S60_2nd_FP3_B\EPOC32\DATA\Z\SYSTEM\APPS\YOURAPP\
C] Error 1

This error is easy to solve. It's just because a definition needed to create the ressource R_LIST_QUERY can't be found. Just check your *.rss file and swap the top lines like this. In short you must have something like this. The avkon.rh and avkon.rsg lines should be swapped like this :

#include <avkon.rsg>
#include <avkon.rh>

Easy SDK switch (posted 28/09/05 by MatD)
The first tricky Symbian configuration problem came when I wanted to develop for UIQ and Series 60. My first try to launch the tools epoc, abld build and makesis was quite disappointing, because a stupid message told me to set the EPOCROOT.

For newbies I must say, it's an incomprenhensible message. Then a kinda setdevices command had to be typed in to correctly launch the emulator : it's not interesting to see the UIQ emulator when you actually wanted to launch the Series60 one ;-) So here's a little help to switch from one environment to the other:

Create an empty *.bat file and type the following into it:

Series60 2nd Ed. Feature Pack 3 Beta :

set EPOCROOT=\Symbian\8.1a\S60_2nd_FP3_B\
devices -setdefault @S60_2nd_FP3_B:com.nokia.series60

Series60 2nd Ed.

set EPOCROOT=\Symbian\7.0s\Series60_v21\
devices -setdefault @Series60_v2_1:com.nokia.Series60_2_1

UIQ 2.1 .

set EPOCROOT=\Symbian\UIQ_21\ devices -setdefault @UIQ_21:com.symbian.UIQ

Now you can switch from one environment to the other without having to worry about changing variables manually!
Nokia 6630 Review (posted 04/27/05 by MatD)
I tought this mobile phone would be the 3G/UMTS "killer" phone. Unfortunately I was quite disappointed to discover that some vital stuff like headphone, IR, Bluetooth Serial Port were missing. Read more >>

Setting up a virtual GSM P2P Network (posted 04/27/05 by MatD)
As a developer I was faced with a tricky problem : I had one day just one USIM Card and I had to test a Peer-2-Peer application I was implementing. The main problem was to found out how I could communicate with my different mobile phones. That's why I decided to play a little bit with the mRouterDeveloper Software and I was able to make a P2P connection from a Sony Ericsson P900 to a Motorola A920.

Fake SIS File issue (posted 04/27/05 by MatD)
One day I had to install and build up a SIS File for an application with many MBM pictures. The total size of my SIS File was 212Kb (lol). The problem was that each time I wanted to install it on my Smartphone, it took a minute and a half to install everything. So I decided to try something : creating an application-less SIS File in order to install my pictures separately in the same directory than my application directory. This method works fine, unless you take a test UID for the SIS File. But be careful ! Don't try to remove your SIS File with the System/Application Manager, because your whole directory would be deleted !

; Installs my configuration files
#{"My Pictures Files"},(0x10005B92),0,0,0
;Supports Series 60 v2.0
(0x101F7960), 0, 0, 0, {"Series60ProductID"}
