The problem I am facing right now is that : How to accept incoming
bluetooth connections on my Symbian mobile phone silently (i.e without
the prompt). I am running a OBEX server which listens for incomming
connections - when a linux machine starts to setup a RFCOMM channel
with the phone on the port of the OBEX server - the user gets a prompt
to accept the incoming connection - how to avoid it and accept that
connection transparently??

Thanks in advance,

Archit Gupta

Pair the devices and set the Linux machine as authorized on the phone. For security reasons, I think, no other way is possible (i.e., no malicious app can accept Bluetooth connections without the phone user seeing/allowing it).

Hi
Thanks for replying Smiley

I have already been able to find solution - actually you can allow other devices to connect without authorization (and malice prevails) - by setting the RBTSecurity parameter of authorization to EFalse. And the pairing technique also works. But I don't want the user to be prompted.

Thanks

Thanks

I am using the BTPMP exaple code:

Code:
void CListener::SetSecurityL(TInt aChannel)
{
// setup channel security
TRequestStatus status;
RBTMan secManager;
RBTSecuritySettings secDatabase;
TBTServiceSecurity secSettings;
// connect to security manager
User::LeaveIfError(secManager.Connect());
CleanupClosePushL(secManager);
User::LeaveIfError(secDatabase.Open(secManager));
CleanupClosePushL(secDatabase);
// setup security
TUid settingsUID;
settingsUID.iUid = KMyApp_serviceID;
secSettings.SetUid(settingsUID);
secSettings.SetChannelID(aChannel);
secSettings.SetProtocolID(KSolBtRFCOMM);
secSettings.SetAuthentication(EFalse);
secSettings.SetAuthorisation(EFalse);
secSettings.SetEncryption(EFalse);
// register settings with security
secDatabase.RegisterService(secSettings, status);
User::WaitForRequest(status);
CleanupStack::PopAndDestroy();  //  secManager
CleanupStack::PopAndDestroy();  //  secSettings
}

Here already set all the authorization to false, even though when ever I try to connect
other device its asking for the passcode. how to resolve this problem. I want to connect
other device silently. Is there any problem with the above code?

Hmm...
For me in the example - btobject exchange - when i set the setting of the obex server to Efalse - the phone no longer prompted for manual authorization. I don't know what is wrong in ur code - seems correct. The only change i made to the application for this is the Efalse setting.

I'm looking for a solution, too. It seems that it differs by devices (SX1 & 6630 woul't ask, 6600 will)  Angry.

Any suggestions, solutions?

Re: How to accept incoming bluetooth connections silently?
For me in the object exchange - the setting worked properly for 6600 - so I don't know what might be the issue.

Re: How to accept incoming bluetooth connections silently?
Sorry for not replying sooner. I am on vacation - and haven't got code with me here. I will post it in a couple of days. -- But the only change I made in the btobjectexchange example code - was to change the setting to Efalse.
Anyway will post it soon Smiley

Good luck!

Re: How to accept incoming bluetooth connections silently?
I changed my function as follows, after that it's not authenticating and silently connecting to the device if the other device is also running my application. Otherwise still it's asking authentication passcode from other device.

Code:
void CListener::SetSecurityL(TInt aChannel)
{
RBTMan secManager;
RBTSecuritySettings secDatabase;
// connect to security manager
User::LeaveIfError(secManager.Connect());
CleanupClosePushL(secManager);
User::LeaveIfError(secDatabase.Open(secManager));
CleanupClosePushL(secDatabase);
// the security settings
TBTServiceSecurity secSettings(KUidMyApplication, KSolBtRFCOMM, 0);

//Define security requirements
secSettings.SetAuthentication(EFalse);
secSettings.SetEncryption(EFalse);
secSettings.SetAuthorisation(EFalse);

secSettings.SetChannelID(aChannel);
TRequestStatus status;
// register settings with security
secDatabase.RegisterService(secSettings, status);

User::WaitForRequest(status); // wait until the security settings are set
User::LeaveIfError(status.Int());

CleanupStack::PopAndDestroy();  //  secManager
CleanupStack::PopAndDestroy();  //  secSettings
}

Anybody have a hint?

Check whether you are included btmanclient.h header file in.

Re: How to accept incoming bluetooth connections silently?
Hi in your code the variable secDatabase is redefined. But I doubt you are using Series 60 SDK 2 Ed FP 2. If that is the case then RBTSecuritySettings class is removed from FP2, but this class is available in the earlier version of SDKs.

Read the file called README_BLUETOOTH.txt that comes with the FP2 setup for more information. If you cant find that text file then I can mail you the same.
