hux 28:307f58df778a 18 // Description
hux 28:307f58df778a 19 //
hux 28:307f58df778a 20 // There are three ways to call enrollment.
hux 28:307f58df778a 21 //
hux 28:307f58df778a 22 // In the first case the service has been setup via a GattService class.
hux 28:307f58df778a 23 // The service is enrolled by registering the service @ GAP. On advertising
hux 28:307f58df778a 24 // the provided broadcast ID is used (otherwise default ID 0xFFFF).
hux 28:307f58df778a 25 //
hux 28:307f58df778a 26 // The second case is based on a Service class object which has been setup
hux 28:307f58df778a 27 // by having added a set of characteristics to the internal collection. Upon
hux 28:307f58df778a 28 // enrollment a GattService instance will be created internally and enroll-
hux 28:307f58df778a 29 // ment of this GattService will be performed according to the first case.
hux 28:307f58df778a 30 //
hux 28:307f58df778a 31 // The third way is to enroll only the service id. This calling syntax is
hux 28:307f58df778a 32 // used, if a Gatt servive is pre-enrolled without enrolling the service ID.
hux 28:307f58df778a 33 //
hux 28:307f58df778a 34 // Example 1: enrollment of GattService
hux 28:307f58df778a 35 //
hux 28:307f58df778a 36 // enroll(o,gservice);
hux 28:307f58df778a 37 // enroll(o,0xFFFF);
