Example

The following example configures an instance of the Heart Rate Monitor (HRM) Service and it's related characteristics:

/*--------- Callback Signatures ----------*/

typedef void (*notify_cb_t ) (BLEClientCharacteristic* chr, uint8_t* data, uint16_t len);

typedef void (*indicate_cb_t) (BLEClientCharacteristic* chr, uint8_t* data, uint16_t len);

BLEUuid uuid;

// Constructors

BLEClientCharacteristic(void);

BLEClientCharacteristic(BLEUuid bleuuid);

// Destructor

virtual ~BLEClientCharacteristic();

void begin(BLEClientService* parent_svc = NULL);

bool discover(void);

bool discovered(void);

uint16_t connHandle(void);

uint16_t valueHandle(void);

uint8_t properties(void);

BLEClientService& parentService(void);

/*------------- Read -------------*/

uint16_t read(void* buffer, uint16_t bufsize);

uint8_t read8 (void);

uint16_t read16(void);

uint32_t read32(void);

/*------------- Write without Response-------------*/

uint16_t write (const void* data, uint16_t len);

uint16_t write8 (uint8_t value);

uint16_t write16 (uint16_t value);

uint16_t write32 (uint32_t value);

/*------------- Write with Response-------------*/

uint16_t write_resp(const void* data, uint16_t len);

uint16_t write8_resp (uint8_t value);

uint16_t write16_resp (uint16_t value);

uint16_t write32_resp (uint32_t value);

/*------------- Notify -------------*/

bool writeCCCD (uint16_t value);

bool enableNotify (void);

bool disableNotify (void);

bool enableIndicate (void);

bool disableIndicate (void);

/*------------- Callbacks -------------*/

void setNotifyCallback(notify_cb_t fp, bool useAdaCallback = true);

void setIndicateCallback(indicate_cb_t fp, bool useAdaCallback = true);
