Hugo Pristauz / Mbed 2 deprecated N06_NAND

A cute tiny piece of code implementing an IoT NAND device, demonstrating how to setup and advertise a cute GATT (NAND) service. The code has been tested on a Nordic nRF51822-DK.

Dependencies:   BLE_API mbed nRF51822

hux 23:2e73c391bb12 1 // collection.h - used to setup a collection of characteristics in order to
hux 23:2e73c391bb12 2 // setup a service.

hux 23:2e73c391bb12 4 // Description:
hux 23:2e73c391bb12 5 // Collections are used to setup a service comprising a collection of
hux 23:2e73c391bb12 6 // characteristics. The setup sequence starts with declaring a collection
hux 23:2e73c391bb12 7 // (this constructs an empty collection) while passing the collection in-
hux 23:2e73c391bb12 8 // stance repeatedly to a constructor of a characteristic, which auto-adds
hux 23:2e73c391bb12 9 // the new constructed characteristics to the collection. Finally, when the
hux 23:2e73c391bb12 10 // collection instance is passed to a service constructor, the service con-
hux 23:2e73c391bb12 11 // structor is able to access all characteristics which have been collected
hux 23:2e73c391bb12 12 // previously.
hux 23:2e73c391bb12 13 //
hux 23:2e73c391bb12 14 // Example 1: A protocol might be declared as a class as follows
hux 23:2e73c391bb12 15 //
hux 23:2e73c391bb12 16 // Collection col; // collection used during setup
hux 23:2e73c391bb12 17 //
hux 23:2e73c391bb12 18 // Characteristic<ObjectId> id(col,0x2AC3,"rw","ID");
hux 23:2e73c391bb12 19 // Characteristic<ObjectName> name(col,0x2ABE,"rw","Name");
hux 23:2e73c391bb12 20 // Characteristic<Digital> presence(col,0x2A56,"r","Presence");
hux 23:2e73c391bb12 21 //
hux 23:2e73c391bb12 22 // Service presenceDetection(col,0xA001); // instantiate service
hux 23:2e73c391bb12 23 //
hux 23:2e73c391bb12 24 // onSetup(Blob &blue)
