Hi,

Bluetooth can be turned on in series60 devices using the notifier.
See my previous posting.. But however this does not work in all symbian devices as it is an undocumented api.

The code below atleast will find out if the bluetooth is ON or OFF.  By this way the code can notify the user to turn on the bluetooth manualy.

This code works in UIQ (p900/p800) as well as in Nokia 9500.

TBool GetBluetoothOn()  // BTONOFF
{
   // Create and initialise an RHostResolver
   RHostResolver hr;
   TInt res = false;
   TBool ret;
   
   RSocketServ socketServer;
   User::LeaveIfError(socketServer.Connect());        
   CleanupClosePushL(socketServer);
   
   res =  hr.Open(socketServer, KBTAddrFamily, BTLinkManager);
   
   if (KErrNone != res) {
      // if not success, this means bluetooth is not on
      ret = EFalse;
   }
   
   else
   {
      ret = ETrue; // Bluetooth is already ON
      hr.Close();
   }
   
   CleanupStack::PopAndDestroy(1);  
   
   return ret;
}

Checking if Bluetooth is ON or OFF (Here is the Ans)
Hi Murali,
My Other queries are ...

1. How to check for missed calls, i.e. if there is a missed call , i want to show the hooked receiver on the top of the screen as it happens usually.

2. How to check whether keypad is locked or not .Similarly in this case i want to show the key on top of the screen as it usually happens .

3. Is there an API to find out which operator network the device is connected to (a string with the name of the network) ?

Thanks

Amit

To check\enable\disable keypad lock use RAknKeyLock. It's a RNotifier inherited class. So:

RAknKeyLock aKeyLock;
aKeyLock.Connect();         //init

aKeyLock.IsKeyLockEnabled();   //return TBool to check if enabled

aKeyLock.EnableKeyLock() or aKeyLock.EnableWithoutNote(); //enables keypad lock

aKeyLock.DisableKeyLock() or aKeyLock.DisableWithoutNote(); //disables keypad lock

aKeyLock.Close();  //must close the notifier

good luck Wink

Re: Checking if Bluetooth is ON or OFF (Here is the Ans)
On Series 60 you can check the first byte of c:\\system\\data\\btstate.dat
to get the BT state

Re: Checking if Bluetooth is ON or OFF (Here is the Ans)
btstat seems to be working very erraticaly. Sometimes the first byte changes and sometimes not.
For getting the BT settings this code works OK:
Code:

                RSharedDataClient sd;
sd.Connect(0);
sd.Assign( TUid::Uid( 0x10005952 ) );
sd.GetInt( _L("Visibility"), aVisibility );
sd.GetInt( _L("PowerMode"), aPower );

but unfortunately the settings don't work. The BT Manager in phone shows the new settings correctly, but actualy the bluetooth still uses old values.

Check out this website:
http://www.cs.helsinki.fi/u/mraento/symbian/reverse.html
The solution works for all Symbian 60 and 80 systems I know

Re: Checking if Bluetooth is ON or OFF (Here is the Ans)
Riho, I've tried your solution...I've created the bteng.h using the pearl source code that you've gave me before (from the link)

Is it only ....

in the header file

#include <bteng.h>
class CBTMCMSettings;
class CMyBlueToothContainer : public CCoeControl, MCoeControlObserver
    {
....
    private: //data
       

      CBTMCMSettings* iBT;
    };


in the .cpp
===================
#include <bteng.h>

void CMyBlueToothContainer::EnableBlueTooth()
    {
  iBT->SetPowerStateL(ETrue, EFalse); 
  }

void CMyBlueToothContainer::DisableBlueTooth()
    {
iBT->SetPowerStateL(EFalse, EFalse);
    }
=======================


Is it only like this? without active object or anything else?
cause...I've tried it and when I want to enable/disable bluetooth....it's "app closed" and then the bluetooth can't be detected by other device until I restart the phone

I tried it on Nokia 6600

Thanx in advance

Irma

Re: Checking if Bluetooth is ON or OFF (Here is the Ans)
You must create a pointer first. These are not static functions.

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

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