Problem with CBluetoothSocket::Accept() multi connection

[Efigenio]

Hi all,
I have written a code for listening a bluetooth connection, but the problem with the code is that it is capable of accepting only one connection. I mean it is listening to only one connection. I have tried to specify the number of connection but then also the result is same below is the code which I have used.

// I have used this for attaching the security settings.
btsockaddr.SetSecurity(secSettings);

// This used for Binding bluetooth socket which is CBluetoothSocket)
User::LeaveIfError(iListenSock->Bind(btsockaddr));

// I have used this for listening the port
iListenSock->Listen(KSizeOfListenQueue); //this is 5

// I have used this for Opening the blank socket and then pass it to accept to be assigned a proper
// And the socket upon completion of Accept()
iSock = CBluetoothSocket::NewL(*this, iSocketServ);

// It is used to Set accept incoming connections,
//which will be handled by the BluetoothNotifier
iListenSock->Accept(*iSock);

According to the reference the call will extracts the first pending connection on the queue of sockets, the queue size before specified by using CBluetoothSocket::Listen(TUint). After the successful completion the blank socket is given the handle for the new socket and it can be used for transfer the data, and after the completer the accept socket is used for making the further connection. Which will be with the new blank sockets. I just want to know what to do now I want to pass the socket to another thread. Finally I want to know how to receive multiple connection using CBluetoothSocket::Accept() multi connection

I am also facing the similar problem, I this simple test MIDlet I am getting followed by about 20 POST’s and final GET to a CGI on the webserver. The weird thing is that after 10 or 11 requests goes through running on the Nokia 3650 I get an IOException with "status -33" which I have learned means timeout. Following getting the first IOException subsequent requirements also timeout. It is as if my net connection is unexpectedly dead. In addition, it consistently happens after about 10 messages.

So my question is this: am I forgetting to clean up some reserve or something and causing the networking layer of the phone to stop? I make sure to close the HTTPConnection and all my streams when I am done with them...

Well I am trying to understand the symptoms as a series of request on the 3650, and after that "Status = -33" and then the following connection will not work.
The thing about the more than 10 request is other than closing all streams, I am unable to think of what could be the exact problem.

This was a while ago and since then we have to tackle the number of network related problem. But after a lot of hard work we have solved the problem.
The problem is because of the access point’s gateway on the 3650. The actual culprit was the default Access point. I do not what is the reason but it is causing the failure after 10 or the HTTP request. Access point on the phone with the use of Gateway Internet Protocol address 0.0.0.0 and then use it for connecting in place of the default access point we have not seen more than 10 request bug.
Below is the Access point settings we have used.

Connection name: you can use any name you want
Data bearer: GPRS
Access point name: Proxy
User name: None
Prompt password: No
Password:
Authentication: Normal
Gateway IP address: 0.0.0.0

I think this will solve your problem.

I have heard about the Gateway of 0.0.0.0 solution, but it is not working for us. I do not know the reason but the internet APN keeps on returning “ Bad request” and then using then using the WAP APN and after that changing the gateway to 0.0.0.0 disables any connectivity. Hence, I am stuck with this problem and have no idea what to do.
