Data Structures
struct	bluetil_ad_data_t
	Struct used for returning the contents of a selected field. More...

struct	bluetil_ad_t
	Descriptor for a buffer containing advertising data. More...

Macros
#define	BLUETIL_AD_INIT(b, p, s)
	Static initializer for the advertising data structure.

#define	BLUETIL_AD_FLAGS_DEFAULT
	Default flags to set when advertising BLE devices.

Enumerations
enum	{ BLUETIL_AD_OK = 0 , BLUETIL_AD_NOTFOUND = -1 , BLUETIL_AD_NOMEM = -2 }
	Return values used by the bluetil_ad module. More...

Functions
void	bluetil_ad_init (bluetil_ad_t ad, void buf, size_t pos, size_t size)
	Initialize the given advertising data descriptor.

int	bluetil_ad_find (const bluetil_ad_t ad, uint8_t type, bluetil_ad_data_t data)
	Find a specific field in the given advertising data.

int	bluetil_ad_find_and_cmp (const bluetil_ad_t ad, uint8_t type, const void val, size_t val_len)
	Find a specific field and compare its value against the given data.

int	bluetil_ad_find_str (const bluetil_ad_t ad, uint8_t type, char str, size_t str_len)
	Find the given field and copy its payload into a string.

int	bluetil_ad_add (bluetil_ad_t ad, uint8_t type, const void data, size_t data_len)
	Add a new field to the given advertising data.

static int	bluetil_ad_add_flags (bluetil_ad_t *ad, uint8_t flags)
	Convenience function to add the "flags" field.

static int	bluetil_ad_add_name (bluetil_ad_t ad, const char name)
	Convenience function to add the "full name" field.

static int	bluetil_ad_init_with_flags (bluetil_ad_t ad, void buf, size_t buf_len, uint8_t flags)
	Convenience function for initializing the advertising data descriptor and directly adding the flags field.
