Constructor & Destructor Documentation

GattCharacteristic ( uint16_t  id = 0,
uint16_t  minLen = 1,
uint16_t  maxLen = 1,
uint8_t  props = 0 
)

Creates a new GattCharacteristic using the specified 16-bit UUID, value length, and properties.

Note:
The UUID value must be unique in the service and is normally >1
Parameters:
[in]idThe 16-bit UUID to use for this characteristic
[in]minLenThe min length in bytes of this characteristic's value
[in]maxLenThe max length in bytes of this characteristic's value
[in]propsThe 8-bit bit field containing the characteristic's properties

EXAMPLE

    // UUID = 0x2A19, Min length 2, Max len = 2, Properties = write
    GattCharacteristic c = GattCharacteristic( 0x2A19, 2, 2, BLE_GATT_CHAR_PROPERTIES_WRITE );
