I've looked at how other projects handle sending large amounts of data and they all use a derivative of the TX/RX scheme that is used in the image transfer demo. The Peripheral waits for a command on the RX characteristic and the notifies the Central on the TX characteristic. It seems like this is a wheel that every company needs to reinvent to add bulk data transfer to their design. Object Transfer Service (OTS ) seems to be a SIG compliant solution to this problem. Does OTS need to be implemented in the phone OS to work? Is the cost/benefit of using OTS not worth it? Is there a better solution than OTS? Am I missing something?
