Detailed Description

Immediate Alert Service module.

This module implements the Immediate Alert Service with the Alert Level characteristic. During initialization it adds the Immediate Alert Service and Alert Level characteristic to the BLE stack database.

The application must supply an event handler for receiving Immediate Alert Service events. Using this handler, the service will notify the application when the Alert Level characteristic value changes.

The service also provides a function for letting the application poll the current value of the Alert Level characteristic.

Note

The application must propagate BLE stack events to the Immediate Alert Service module by calling ble_ias_on_ble_evt() from the ble_stack_handler callback.

Attention! To maintain compliance with Nordic Semiconductor ASA Bluetooth profile qualification listings, this section of source code must not be modified.

Enumeration Type Documentation

enum ble_ias_evt_type_t

Immediate Alert Service event type.

Enumerator
BLE_IAS_EVT_ALERT_LEVEL_UPDATED	Alert Level Updated event.

Function Documentation

uint32_t ble_ias_alert_level_get	(	ble_ias_t *	p_ias,
		uint8_t *	p_alert_level
	)

Function for getting current value of the Alert Level characteristic.

Parameters

[in]	p_ias	Immediate Alert Service structure.
[out]	p_alert_level	Current Alert Level value.

uint32_t ble_ias_init	(	ble_ias_t *	p_ias,
		const ble_ias_init_t *	p_ias_init
	)

Function for initializing the Immediate Alert Service.

Parameters

[out]	p_ias	Immediate Alert Service 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 service instance.
[in]	p_ias_init	Information needed to initialize the service.

Returns

NRF_SUCCESS on successful initialization of service, otherwise an error code.

void ble_ias_on_ble_evt	(	ble_ias_t *	p_ias,
		ble_evt_t *	p_ble_evt
	)

Function for handling the Application's BLE Stack events.

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

Parameters

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