Separate NSData into smaller NSMutableData objects

Question

I am unsure of how to separate a NSData object into smaller parts so that I can send it over bluetooth. I believe it is a method similar to this:

- (void)getBytes:(void *)buffer range:(NSRange)range

I do not know what to pass in for the buffer. Do I just pass in a NSMutableData object to hold the bytes that I pull out of the original NSData?

Thanks

You can use the -subdataWithRange: method.
