Function Documentation

bcs_indicate()

ble_error_t bcs_indicate	(	ble_service_t *	svc,
		uint16_t	conn_idx,
		bcs_body_measurement_t *	meas
	)

Indicate body composition measurement to client

Indicate will only be sent if given client enabled indications before.

Parameters

[in]	svc	BCS instance
[in]	conn_idx	connection index
[in]	meas	body composition measurement

Returns

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

bcs_indicate_all()

void bcs_indicate_all	(	ble_service_t *	svc,
		bcs_body_measurement_t *	meas
	)

Indicate body composition measurement to all connected clients

This is roughly equivalent for calling bcs_indicate() for each connected client.

Parameters

[in]	svc	BCS instance
[in]	meas	body composition measurement

bcs_init()

ble_service_t* bcs_init	(	const ble_service_config_t *	config,
		bcs_feat_t	feat,
		const bcs_callbacks_t *	cb
	)

Register Body Composition Service instance

Parameters

[in]	config	service configuration
[in]	cb	application callbacks
[in]	feat	body composition features

Returns

BCS instance

bcs_is_indication_enabled()

bool bcs_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
