// advertise.h - begin peripheral role and start advertising
//
// Synopsis:
//
//    advertise(O&o);           
//    advertise(O&o, const char *mode, int ms = 100);
//
//    payload(O&o,const char *mode)       // set advertising payload
//
// Arguments:
//
//    o:     Blob object (to avoid name clashes)
//    mode:  String containing a sequence of mode characters defining both
//           advertising type (upper case characters) and advertising flags 
//           (lower case characters), some of which have meaning, all others
//           are ignored and can be used for spacing (e.g. ':', ' ', '-', ...)
//    ms:    Advertising interval in mili seconds (default 100 ms)
//
// Advertising Type 
//
//    C:    ADV_CONNECTABLE_UNDIRECTED
//    D:    ADV_CONNECTABLE_DIRECTED
//    S:    ADV_SCANNABLE_UNDIRECTED
//    N:    ADV_NON_CONNECTABLE_UNDIRECTED
//
// Advertising Flags:
//
//    l:   LE Limited Discoverable Mode           (value: 0x01)
//    g:   LE General Discoverable Mode           (value: 0x02)
//    n:   BR/EDR Not Supported                   (value: 0x04)
//    c:   Controller: simultaneous LE & BR/EDR   (value: 0x08)
//    h:   Host: Simultaneous LE & BR/EDR         (value: 0x10)
//    
// Examples 1: Start advertising in peripheral role with type 'connectable, uni-
// directed, and flags 'BR/EDR Not Supported', 'LE General Discoverable Mode'
//
//    advertise(o,"C:ng",100);   // start advertising @ 100 msec interval
//    advertise(o,"Cng",100);    // same as above
//    advertise(o,"gCn",100);    // same as above
//
// Examples 2: Start advertising in peripheral role with type 'connectable,
// directed, and flags 'LE Limited Discoverable Mode'
//
//    advertise("D:l",100)       // Connectable Directed, limited discoverable
//
// Examples 3: A typical peripheral advertising session starts with setup of
// device name, advertising name and advertising data.
//
//    device(o,"Smart Button");        // setup device name
//    name(o,"Smart Button #1");       // setup advertising name
//    data(o,"My Home");               // setup advertising data
//    advertise(o,"C:ng",100);         // start advertising @ 100 msec interval
//
// Example 4: restart advertising based on pre-defined advertising payload
//
//
