Detailed Description

The model of a BLE Characteristic.

A BLE Characteristic is an identified value container that manages a value. It is exposed by a BLE server and can be read and written to by a BLE client.

Examples

nordic-nrf52-dk/BLEGATTServer/main.cpp.

Member Function Documentation

notify()

void BLECharacteristic::notify

(

bool

is_notification = true

)

Send a notify. A notification is a transmission of up to the first 20 bytes of the characteristic value. An notification will not block; it is a fire and forget.

Returns

N/A.

setValue()

void BLECharacteristic::setValue	(	uint8_t *	data,
		size_t	size )

Set the value of the characteristic.

Parameters

[in]	data	The data to set for the characteristic.
[in]	length	The length of the data in bytes.
