Can we send NSString Value between devices connected via bluetooth, Using Game Center - nsstring

Question

Can we send NSString Value between devices connected via Bluetooth, using Game Center?
Here is some part of my code:
typedef enum {
messageType1 = 0;
messageType2 = 1;
}
messageType;
typedef struct {
MessageType messageType;
NSString *myName;
} MyMessage;
And In my Class I have this method to send the message:
MyMessage myMessage;
myMessage.messageType = messageType2;
myMessage.myName = #"ABCDEFGH";
NSData *data = [NSData dataWithBytes:&myMessage length:sizeof(MyMessage)];
[self sendDataToAllPeers:data withDataMode:GKSendDataReliable error:error];
to receive data I have method:
-(void) receiveData:(NSData *)data fromPeer:(NSString *)peer inSession: (GKSession *)session context:(void *)context{
MyMessage myMessage = *((MyMessage *) [data bytes]);
type = myMessage.messageType;
name = myMessage.myName;
}
Question: How can I get myName ? (I am able to get MessageType)

Send NSData as Archived NSArray:
NSArray *array = [[NSArray alloc] initWithObjects:myMessage.messageType, myMessage.myName, nil];
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:array];
[self sendDataToAllPeers:data];
Receive NSData and Unarchive to NSArray:
NSArray *array = [NSKeyedUnarchiver unarchiveObjectWithData: data];
type = [array objectAtIndex:0];
name = [array objectAtIndex:1];
