Detailed Description

Immediate Alert Service Client module.

This module implements the Immediate Alert Service client - locator role of the Find Me profile. On BLE_GAP_EVT_CONNECTED event, this module starts discovery of the Immediate Alert Service with Alert Level characteristic at the peer. This module will indicate the application about a successful service & characteristic discovery using BLE_IAS_C_EVT_CHAR_DISCOVERED event. The application can use ble_ias_c_send_alert_level function to signal alerts to the peer.

Note

The application must propagate BLE stack events to this module by calling ble_ias_c_on_ble_evt() from the from the ble_stack_handler callback function.

Enumeration Type Documentation

enum ble_ias_c_evt_type_t

Immediate Alert Service client event type.

Enumerator
BLE_IAS_C_EVT_SRV_DISCOVERED	Event indicating that the Immediate Alert Service is found at the peer.
BLE_IAS_C_EVT_SRV_NOT_FOUND	Event indicating that the Immediate Alert Service is not found at the peer.
BLE_IAS_C_EVT_DISCONN_COMPLETE	Event indicating that the Immediate Alert Service client module has completed the processing of BLE_GAP_EVT_DISCONNECTED event. This event is raised only if a valid instance of IAS was found at the peer during the discovery phase. This event can be used the application to do clean up related to the IAS Client.

Function Documentation

uint32_t ble_ias_c_init	(	ble_ias_c_t *	p_ias_c,
		const ble_ias_c_init_t *	p_ias_c_init
	)

Function for initializing the Immediate Alert Service client.

This call allows the application to initialize the Immediate Alert Service client.

Parameters

[out]	p_ias_c	Immediate Alert Service client structure. This structure will have to be supplied by the application. It will be initialized by this function, and will later be used to identify this particular client instance.
[in]	p_ias_c_init	Information needed to initialize the Immediate Alert Service client.

Returns

NRF_SUCCESS on successful initialization of service.

void ble_ias_c_on_ble_evt	(	ble_ias_c_t *	p_ias_c,
		const ble_evt_t *	p_ble_evt
	)

Function for handling the Application's BLE Stack events for Immediate Alert Service client.

Handles all events from the BLE stack of interest to the Immediate Alert Service client.

Parameters

[in]	p_ias_c	Immediate Alert Service client structure.
[in]	p_ble_evt	Event received from the BLE stack.

uint32_t ble_ias_c_send_alert_level	(	const ble_ias_c_t *	p_ias_c,
		uint8_t	alert_level
	)

Function for sending alert level to the peer.

This function allows the application to send an alert to the peer.

Parameters

[in]	p_ias_c	Immediate Alert Service client structure.
[in]	alert_level	Required alert level to be sent to the peer.

Returns

NRF_SUCCESS on success, otherwise an error code.
