i tried to run the code below :
RHostResolver hr;
TInt res = false;
bool BTon = 0;

RSocketServ socketServer;
User::LeaveIfError(socketServer.Connect());
CleanupClosePushL(socketServer);

TProtocolDesc pInfo;
User::LeaveIfError(socketServer.FindProtocol(_L("BTLinkManager"),pInfo));
User::LeaveIfError(res = hr.Open(socketServer, KBTAddrFamily, pInfo.iProtocol));

if (res != KErrNone) { //BT = OFF
BTon = 0;
}else{
BTon = 1; //BT = ON
hr.Close();
}
CleanupStack::PopAndDestroy(1);

But the value of res= -1 in the statement User::LeaveIfError(res = hr.Open(socketServer, KBTAddrFamily, pInfo.iProtocol));
as a result the program panic.....

Plz help me.......

Use Dumpbin /EXPORTS *.lib

Obviously you can only dump WINS binaries with dumpbin utility.Â

"Rino" when talking about "this class" it would be intresting to
know if you mean CBTMCMSettings or CSettingInfo ?

CBTMCMSettings does exists for S60v1 (Symbian 6.1) phones, so I assume you mean CSettingsInfo.

Most software needs some rewrites for New major release. Also many times minor releases. If you are working with specific features, they may not be even available. Like it or not this is the symbian way.

Also this class has been removed from 3rd edition

This is not supported in older ver.6 phones. If you support only new phones then it's probably OK.

A much simpler method using CSettingInfo::Get (SettingInfo::EBluetoothPowerMode) seems to work all right for me on a Nokia 6600. Are there any reasons to avoid using it, maybe some incompatibilities on other phone models?

Re: Checking if Bluetooth is ON or OFF (Here is the Ans)

riho — Thu, 16 Mar 2006 15:46:29 +0100

Has anyone figured out the same stuff for 3rd edition?

TInt GetConnectionStatus(int &a); ?

I need to know in my app if BT is activated or not in the phone, so I tried the first method exposed in this thread but it always returns true (BTon = 1). Does anyone know another method to get it? Did I forget something?

Code:

RHostResolver hr;
TInt res = false;
bool BTon = 0;

RSocketServ socketServer;
User::LeaveIfError(socketServer.Connect());
CleanupClosePushL(socketServer);

TProtocolDesc pInfo;
User::LeaveIfError(socketServer.FindProtocol(_L("BTLinkManager"),pInfo));
User::LeaveIfError(res = hr.Open(socketServer, KBTAddrFamily, pInfo.iProtocol));

if (res != KErrNone) { //BT = OFF
BTon = 0;
}else{
BTon = 1; //BT = ON
hr.Close();
}
CleanupStack::PopAndDestroy(1);

Thanks in advance!

I have checked this S60V2FP1 SDK with Borland tools and tested on Nokia 6630.

... and Nokia 6600

Here are short instructions that are supposed to readable without quesing anything and without having old version Visual C++ dumpbin.exe.

bteng.h

Code:

#ifndef BT_ENG_HACK_H
#define BT_ENG_HACK_H
// link against BTENG.LIB copied from SDK 1.2

// these are headers that are just not included
// in the SDK, so I had to reverse engineer them
//C:\Symbian\tilion\group>"c:\Program Files\Borland\CBuilder6\Bin\expdump.exe"
// C:\Symbian\Series60_1_2_B\epoc32\release\winsb\udeb\BTENG.LIB
class MBTMCMSettingsCB
{
};
class CBTMCMSettings;
class CBTMCMSettings
{
public:

static CBTMCMSettings* NewLC(MBTMCMSettingsCB *x);
static CBTMCMSettings* NewL(MBTMCMSettingsCB *x);

void SetPowerStateL(TBool a, TBool b);
void GetPowerStateL(TBool &a);
TInt GetConnectionStatus(int &a);
};
#endif

Then you need to install SDK 1.2.

Then you need to copy bteng.lib file from:
C:\Symbian\Series60_1_2_B\epoc32\relese\armi\udeb
to:
C:\Symbian\7.0s\Series60_v21\Epoc32\release\armi\udeb
and

C:\Symbian\Series60_1_2_B\epoc32\relese\armi\urel
to:
C:\Symbian\7.0s\Series60_v21\Epoc32\release\armi\urel
(and same to thumb).

You need to link againts
bteng.lib in mmp file.

And the following code will turn on BT.
The compiled code works with 6630.

Code:

// turn on Bluetooth in case it was off
settings= CBTMCMSettings::NewL( (MBTMCMSettingsCB*)NULL );

settings->SetPowerStateL(ETrue,EFalse ); // on, off is (EFalse,EFalse)

I have checked this S60V2FP1 SDK with Borland tools and tested on N6630.

I have not cheked this with emulator, but no-one has the BT/internet working with the emulator anyway.

I have no Visual C++ 6.0

I Tried the dumpbin from microsoft SDK, but it is obisiously not doing what itis supposed to.

Can someone email me the headers created from that lib?

My email jkekoni@utbl.net

How about UIQ 2.1???

How to turn on Bluetooth on UIQ?

In UIQ there is no BTEng.dll and there's no btnotif.h.

Anyone has the solution?

Re: Checking if Bluetooth is ON or OFF (Here is the Ans)

riho — Mon, 15 Aug 2005 10:25:14 +0200

You must create a pointer first. These are not static functions.

Code:

CBTMCMSettings * btset=CBTMCMSettings::NewLC(NULL);
btset->SetPowerStateL(ETrue,EFalse);
CleanupStack::PopAndDestroy();
