Function Documentation

wss_indicate_weight()

ble_error_t wss_indicate_weight	(	ble_service_t *	svc,
		uint16_t	conn_idx,
		const wss_weight_measurement_t *	measurement
	)

Send weight indication to client.

Function sends indication to selected client.

Parameters

[in]	svc	service instance
[in]	conn_idx	connection index to sent indication to
[in]	measurement	characteristic value to send

Returns

0 (BLE_STATUS_OK) if indication was sent successfully, ble_error_t if error occured

wss_indicate_weight_all()

void wss_indicate_weight_all	(	ble_service_t *	svc,
		const wss_weight_measurement_t *	measurement
	)

Send weight indication to all interested clients.

Parameters

[in]	svc	service instance
[in]	measurement	characteristic value to send

Returns

service instance

wss_init()

ble_service_t* wss_init	(	const ble_service_config_t *	config,
		wss_feature_t	features,
		const wss_callbacks_t *	cb
	)

Register Weight Scale Service instance.

Function registers Weight Scale Service with give set of features.

Parameters

[in]	config	service configuration
[in]	features	bit mask of supported features
[in]	cb	application callbacks

Returns

service instance

wss_is_indication_enabled()

bool wss_is_indication_enabled	(	ble_service_t *	svc,
		uint16_t	conn_idx
	)

Check if indication is enabled.

Parameters

[in]	svc	service instance
[in]	conn_idx	connection index to sent indication to

Returns

true if indication is enabled, false otherwise
