socket connection in E61

[inguvaseshu]

Hi,
I have a problem with UDP connection on E61. Every thing works fine on emulator, but on device (E61) it’s not working. I have a developer certificate with all capabilities given by Symbian. Every thing works fine even opening connection and all. Do we need to write capabilities in pkg file for socket connection? Pls clarify this. Anybody have problem like this on 9.1 devices pls help me!
Do we need to "bind" socket? Or setLocalPort() is enough. Initially I tried binding but after successful binding it’s not able to send a packet. And with SetLocalPort only it was able to send a packet. This method worked on 2nd edition fp2. Did this change in version 3 devices?

Thanks & Regards,

Hi,
I have exactly the same problem so you are not alone with this.

Everything is working fine in the emulator and also in the phone everything seems to work except no data is received. I'm using Nokia E70 + developer license.

Here is my connection code which works fine in the emulator.

// Creating connection classes...
iSocketServ = new (ELeave) RSocketServ;
iConnection = new (ELeave) RConnection;
iSocket = new (ELeave) RSocket;

User::LeaveIfError( iSocketServ->Connect() );
// Here phone asked the WLAN access point I'm using.
User::LeaveIfError( iConnection->Open(*iSocketServ) );
User::LeaveIfError( iConnection->Start() );

// ...opening socket...
User::LeaveIfError( iSocket->Open( *iSocketServ, KAfInet, KSockDatagram, KProtocolInetUdp, *iConnection) );
User::LeaveIfError( iSocket->SetLocalPort( iServerPort ) );
User::LeaveIfError( iSocket->SetOpt( KSoReuseAddr, KProtocolInetIp, 1 ) );

// ...and here emulator is receiving data but the phone isn't.
iSocket->RecvFrom( iDataBuf, iSockAddrCurrent, 0 , iStatus );

Thanks for your reply i am not alone with this issue, is there any solution for this? do we need some privilages to work on device? Any thing we need to add to pkg?

Hi,
Do i need to change these for developer certificate

app uid - 0xA000017F

__EMULATOR_IMAGE_HEADER2(0x1000007a,0x100039ce,0xa000017f,EPriorityForeground,0x00000000u,0x00000000u,0xa000017f,0x00000000,0x00010000,0) in file app_UID.cpp

In s60_3_0_how_to_sign_sis_files_1_4.pdf this was given

3. Checklist
Things to check while creating a self signed .sis file:
• Make sure that the package UID is not within the protected range (that is, that it is not less than 0x80000000)
• Make sure that the SID is not within the protected range (that is, not less than 0x80000000)
• Make sure that the Vendor id is 0
• Make sure that your applicatons have a capability set that is less/equal than/to the following:
o NetworkServices
o LocalServices
o ReadUSerData
o WriteUserData
o UserEnvironment

where do we set this capability?

Thanks & Regards,

Set the emulator to display any missing capability when running your program. These should be displayed in the debug window. You define the necessary capabilities in the mmp file. If it still doesn't work, use some logging to a) determine where it's failing b) what error code you're getting

[inguvaseshu]

My code is working in Emulator properly. And for device i got all capabilities that Symbian can give in developer certificate. In their developer certificate documentation they mentioned that if certification satisfies code capabilities then it will work! Will udp comes under CommDD (phone manufacturer capability?)

I need some help; do we need to specify the capabilities in mmp? Can you pls write some code how to add that capability for Network services and multimediaDD?

Do I need to import project from mmp again (after adding capabilities) or CW will get them from MMP?

Thanks & Regards,

Hi,

for RSocket::sendTo i am getting error -46(KErrPermissionDenied ). how can we add permission?

Thanks & Regards,
Sheshu Kumar Inguva.

[david.caabeiro]

That it "does work" on the emulator doesn't mean you have some missing capability. Check the debug window for these messages, as I already mentioned. You need to specify them in the mmp file and also reimport (an clean everything up to make sure).

Regarding code snippets, please dedicate some time on your own to read documentation, which explains this very well (including examples, etc)

[inguvaseshu]

Ok thanks,

I got this from SIP example given

CAPABILITY     NetworkServices LocalServices Location ReadUserData \
               WriteUserData WriteDeviceData SwEvent ProtServ

i am reimporting my project.

I have a doubt regarding UID for using developer certificate. do we need to do use unprotected uid or Developement use only?

0x00000000 - 0x0FFFFFFF
Development use only

0x10000000 - 0x1FFFFFFF
Legacy UID allocations 

0x20000000 - 0x2FFFFFFF
V9 protected UID allocations 

0xA0000000 - 0xAFFFFFFF
V9 unprotected UID allocations 

0xE0000000 - 0xEFFFFFFF
Development use only

currently i am using unprotected uid 0xA000017F.

Thanks & Regards,

[inguvaseshu]

Its working now!

I added capabilities in mmp file and reimported.

Hi

I am also using E61 device

I am trrying to write Irda application

But i am not able to connect as my RSocket.Connect is failing and in RunL i am getting "KErrDisconnected" error message..


This is my connect call...
