Sending Data Over Bluetooth

Ok so i am trying to send an array of objects over bluetooth.

I have successfuly created the session and all the methods get called at the right time.

Code:

NSData *data = [NSKeyedArchiver archivedDataWithRootObject: array];
[session sendDataToAllPeers:data withDataMode:GKSendDataReliable error:nil];

and in my recieve data method:

Code:

NSArray *newArray = [NSKeyedUnarchiver unarchiveObjectWithData:data];

but i try to loop through the newArray object to see what is in it but its count is 0. why is it not successfully sending the array object over bluetooth?
