prime31 GameKit plugin slow connection problem

Hi,

I am using prime31 plugins and need to connect six devices with one host device. Host device becomes very slow while transferring data.

I am launching my host device like this

Code (csharp):

1.  
2. GameKitBinding.setSessionMode(GameKitSessionMode.Server);
3. GameKitBinding.setAutoConnectPeers(true);
4. GameKitBinding.initializeSessionForOnlineOnly();
5.  

and I am launching client device to search server like this

Code (csharp):

1.  
2. GameKitBinding.setSessionMode(GameKitSessionMode.Peer);
3. GameKitBinding.showPeerPicker(false);
4.  

am I doing any thing wrong?
Also, When 4th device normally tries to connect it shows connection lost and then I try to connect again.

What is the maximum length of data we can transfer at a time in bluetooth.
This slow speed is creating problem for me.

thanks
chishti

 

Any one could share with me the best practice in this case?
