Example

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

virtual err_t begin(void);

// Add Descriptor function must be called right after begin()

err_t addDescriptor(BLEUuid bleuuid, void const * content, uint16_t len, BleSecurityMode read_perm = SECMODE_OPEN, BleSecurityMode write_perm = SECMODE_NO_ACCESS);

ble_gatts_char_handles_t handles(void);

/*------------- Write -------------*/

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

uint16_t write(const char* str);

uint16_t write8 (uint8_t num);

uint16_t write16 (uint16_t num);

uint16_t write32 (uint32_t num);

uint16_t write32 (int num);

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

uint16_t read(void* buffer, uint16_t bufsize);

uint8_t read8 (void);

uint16_t read16(void);

uint32_t read32(void);

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

uint16_t getCccd(void);

bool notifyEnabled(void);

bool notify(const void* data, uint16_t len);

bool notify(const char* str);

bool notify8 (uint8_t num);

bool notify16 (uint16_t num);

bool notify32 (uint32_t num);

bool notify32 (int num);

/*------------- Indicate -------------*/

bool indicateEnabled(void);

bool indicate(const void* data, uint16_t len);

bool indicate(const char* str);

bool indicate8 (uint8_t num);

bool indicate16 (uint16_t num);

bool indicate32 (uint32_t num);

bool indicate32 (int num);
