Detailed Description

Device information Service Client module.

This module contains the APIs and types exposed by the Device information Service Client module. These APIs and types can be used by the application to perform discovery of the Device information Service at the peer and interact with it.

Note: The application must register this module as BLE event observer using the NRF_SDH_BLE_OBSERVER macro. Example:
ble_dis_c_t instance;

NRF_SDH_BLE_OBSERVER(anything, BLE_DIS_C_BLE_OBSERVER_PRIO,

ble_dis_c_on_ble_evt, &instance);

Macro Definition Documentation

#define BLE_DIS_C_ARRAY_DEF	(	_name,
		_cnt
	)

Macro for defining multiple ble_dis_c instances.

Parameters

_name	Name of the array of instances.
_cnt	Number of instances to define.

#define BLE_DIS_C_DEF ( _name )

Macro for defining a ble_dis_c instance.

Parameters

_name Name of the instance.

Typedef Documentation

typedef void(* ble_dis_c_evt_handler_t)(ble_dis_c_t *p_ble_dis_c, ble_dis_c_evt_t const *p_evt)

Event handler type.

This is the type of the event handler that should be provided by the application of this module to receive events.

Enumeration Type Documentation

enum ble_dis_c_char_type_t

DIS Client characteristic type.

Enumerator
BLE_DIS_C_MANUF_NAME	Manufacturer Name String characteristic.
BLE_DIS_C_MODEL_NUM	Model Number String characteristic.
BLE_DIS_C_SERIAL_NUM	Serial Number String characteristic.
BLE_DIS_C_HW_REV	Hardware Revision String characteristic.
BLE_DIS_C_FW_REV	Firmware Revision String characteristic.
BLE_DIS_C_SW_REV	Software Revision String characteristic.
BLE_DIS_C_SYS_ID	System ID characteristic.

BLE_DIS_C_PNP_ID	PnP ID characteristic.
BLE_DIS_C_CHAR_TYPES_NUM	Number of all possible characteristic types.

enum ble_dis_c_evt_type_t

DIS Client event type.

Enumerator
BLE_DIS_C_EVT_DISCOVERY_COMPLETE	Event indicating that the DIS and its characteristics were discovered. See ble_dis_c_evt_disc_complete_t.
BLE_DIS_C_EVT_DIS_C_READ_RSP	Event indicating that the client has received a read response from a peer. See ble_dis_c_evt_read_rsp_t.
BLE_DIS_C_EVT_DIS_C_READ_RSP_ERROR	Event indicating that the client's read request has failed. See ble_dis_c_evt_read_rsp_err_t.
BLE_DIS_C_EVT_DISCONNECTED	Event indicating that the DIS server has disconnected.

Function Documentation

ret_code_t ble_dis_c_handles_assign	(	ble_dis_c_t *	p_ble_dis_c,
		uint16_t	conn_handle,
		ble_dis_c_handle_t const *	p_peer_handles
	)

Function for assigning handles to this instance of dis_c.

Call this function when a link has been established with a peer to associate this link to this instance of the module. This makes it possible to handle several links and associate each link to a particular instance of this module. The connection handle and attribute handles will be provided from the discovery event BLE_DIS_C_EVT_DISCOVERY_COMPLETE.

Parameters

[in]	p_ble_dis_c	Pointer to the DIS client structure instance to associate with these handles.
[in]	conn_handle	Connection handle associated with the given DIS Instance.
[in]	p_peer_handles	Attribute handles on the DIS server that you want this DIS client to interact with.

Return values

NRF_SUCCESS	If the operation was successful.
NRF_ERROR_NULL	If a `p_ble_dis_c` was a NULL pointer.

ret_code_t ble_dis_c_init	(	ble_dis_c_t *	p_ble_dis_c,
		ble_dis_c_init_t *	p_ble_dis_c_init
	)

Function for initializing the Device Information service client module.

This function registers with the Database Discovery module for the DIS. Doing so will make the Database Discovery module look for the presence of a DIS instance at the peer when a discovery is started.

Parameters

[in]	p_ble_dis_c	Pointer to the DIS client structure.
[in]	p_ble_dis_c_init	Pointer to the DIS initialization structure containing the initialization information.

Return values

NRF_SUCCESS	If the module was initialized successfully.
NRF_ERROR_NULL	Any parameter is NULL.

Returns: If functions from other modules return errors to this function (ble_db_discovery_evt_register), the SoftDevice Global Error Codes are propagated.

void ble_dis_c_on_ble_evt	(	ble_evt_t const *	p_ble_evt,
		void *	p_context
	)

Function for handling BLE events from the SoftDevice.

This function handles the BLE events received from the SoftDevice. If a BLE event is relevant to the DIS module, it is used to update internal variables and, if necessary, send events to the application.

Parameters

[in]	p_ble_evt	Pointer to the BLE event.
[in]	p_context	Pointer to the DIS client structure.

void ble_dis_c_on_db_disc_evt	(	ble_dis_c_t *	p_ble_dis_c,
		ble_db_discovery_evt_t *	p_evt
	)

Function for handling events from the database discovery module.

This function will handle an event from the database discovery module, and determine if it relates to the discovery of DIS at the peer. If so, it will call the application's event handler indicating that DIS has been discovered at the peer. It also populates the event with the service related information before providing it to the application.

Parameters

[in]	p_ble_dis_c	Pointer to the DIS client structure.
[in]	p_evt	Pointer to the event received from the database discovery module.

ret_code_t ble_dis_c_read	(	ble_dis_c_t *	p_ble_dis_c,
		ble_dis_c_char_type_t	char_type
	)

Function for reading different characteristics from DIS.

This function can be used to read different characteristics that are available inside DIS. The response data will be provided from the response event BLE_DIS_C_EVT_DIS_C_READ_RSP. The BLE_DIS_C_EVT_DIS_C_READ_RSP_ERROR event can be generated if the read operation is unsuccessful.

Parameters

[in]	p_ble_dis_c	Pointer to the DIS client structure.
[in]	char_type	Type of characteristic to read.

Return values

NRF_SUCCESS	If the operation was successful.
NRF_ERROR_NULL	If a `p_ble_dis_c` was a NULL pointer.
NRF_ERROR_INVALID_PARAM	If a `char_type` is not valid.
NRF_ERROR_INVALID_STATE	If connection handle or attribute handle is invalid.
NRF_ERROR_NO_MEM	If the client request queue is full.
