How to define 128bit UUID

Hi,

I pretty much have my project complete. With the CC2541 doing what it's supposed to and an iPhone app doing as it should.

I have a problem where I need to put the UUID of the CC2541 into the iPhone app so it will only scan for devices of that type.

I have tried connecting to the CC2541 and also packet sniffing the CC2541, but I cant find the UUID.

What i'd like to do is use my own UUID's like I do in xcode like this:

#define TRANSFER_SERVICE_UUID           @"FCA3E988-4D5A-435E-A645-C54397BC8077"

#define TRANSFER_CHARACTERISTIC_UUID    @"36D49865-9BC0-4C6E-BDB3-D1ACF9695A96"

How would I define these UUID's to be used in the SimpleBLEPeripheral project for Service and Characteristic?

Many Thanks
