Function Documentation

le_wifiClient_NewEventHandlerRef_t le_wifiClient_AddNewEventHandler	(	le_wifiClient_NewEventHandlerFunc_t	handlerPtr,
		void *	contextPtr
	)

Add handler function for EVENT 'le_wifiClient_NewEvent'

This event provide information on WiFi Client event changes.

Parameters

[in]	handlerPtr
[in]	contextPtr

le_result_t le_wifiClient_Connect ( le_wifiClient_AccessPointRef_t accessPointRef )

Connect to the WiFi Access Point. All authentication must be set prior to calling this function.

Returns

LE_OK Function succeeded.
LE_BAD_PARAMETER Invalid parameter.

Note: For PSK credentials see le_wifiClient_SetPassphrase() or le_wifiClient_SetPreSharedKey() .; For WPA-Enterprise credentials see le_wifiClient_SetUserCredentials()

Parameters

[in] accessPointRef WiFi Access Point reference.

void le_wifiClient_ConnectService ( void )

Connect the current client thread to the service providing this API. Block until the service is available.

For each thread that wants to use this API, either ConnectService or TryConnectService must be called before any other functions in this API. Normally, ConnectService is automatically called for the main thread, but not for any other thread. For details, see Client-specific Functions.

This function is created automatically.

le_wifiClient_AccessPointRef_t le_wifiClient_Create	(	const uint8_t *	SsidPtr,
		size_t	SsidSize
	)

This function creates a reference to an Access Point given its SSID. If an Access Point is hidden, it will not show up in the scan. So, its SSID must be known in advance in order to create a reference.

Returns

AccessPoint reference to the current Access Point.

Note: This function fails if called while scan is running.

Parameters

[in]	SsidPtr	The SSID as a octet array.
[in]	SsidSize

le_result_t le_wifiClient_Delete ( le_wifiClient_AccessPointRef_t accessPointRef )

Deletes an accessPointRef.

Returns

LE_OK Function succeeded.
LE_BAD_PARAMETER Invalid parameter.
LE_BUSY Function called during scan.

Note: The handle becomes invalid after it has been deleted.

Parameters

[in] accessPointRef WiFi Access Point reference.

le_result_t le_wifiClient_Disconnect ( void )

Disconnect from the current connected WiFi Access Point.

Returns

LE_OK Function succeeded.
LE_FAULT Function failed.

void le_wifiClient_DisconnectService ( void )

Disconnect the current client thread from the service providing this API.

Normally, this function doesn't need to be called. After this function is called, there's no longer a connection to the service, and the functions in this API can't be used. For details, see Client-specific Functions.

This function is created automatically.

Returns

WiFi Access Point reference if ok.
NULL If no Access Point reference available.

le_wifiClient_AccessPointRef_t le_wifiClient_GetNextAccessPoint ( void )

Get the next WiFi Access Point. Will return the Access Points in the order of found. This function must be called in the same context as the GetFirstAccessPoint

Returns

WiFi Access Point reference if ok.
NULL If no Access Point reference available.

int16_t le_wifiClient_GetSignalStrength ( le_wifiClient_AccessPointRef_t accessPointRef )

Get the signal strength of the AccessPoint

		uint8_t *	ssidPtr,
		size_t *	ssidSizePtr
	)

Get the Service set identification (SSID) of the AccessPoint

Returns: LE_OK Function succeeded. LE_FAULT Function failed. LE_BAD_PARAMETER Invalid parameter. LE_OVERFLOW ssid buffer is too small to contain the SSID.

Note: The SSID does not have to be human readable ASCII values, but often is.

Parameters

[in]	accessPointRef	WiFi Access Point reference.
[out]	ssidPtr	The SSID returned as a octet array.
[in,out]	ssidSizePtr

void le_wifiClient_RemoveNewEventHandler ( le_wifiClient_NewEventHandlerRef_t handlerRef )

Remove handler function for EVENT 'le_wifiClient_NewEvent'

Parameters

[in] handlerRef

le_result_t le_wifiClient_Scan ( void )

Start Scanning for WiFi Access points Will result in event LE_WIFICLIENT_EVENT_SCAN_DONE when the scan results are available.

This function specifies whether the target Access Point is hiding its presence from clients or not. When an Access Point is hidden, it cannot be discovered by a scan process.

Returns

LE_OK Function succeeded.
LE_BAD_PARAMETER Invalid parameter.

Note: By default, this attribute is not set which means that the client is unable to connect to a hidden access point. When enabled, the client will be able to connect to the access point whether it is hidden or not.

Parameters

[in]	accessPointRef	WiFi Access Point reference.
[in]	hidden	If TRUE, the WIFI client will be able to connect to a hidden access point.

le_result_t le_wifiClient_SetPassphrase	(	le_wifiClient_AccessPointRef_t	accessPointRef,

Returns

LE_OK Function succeeded.
LE_FAULT Function failed.
LE_BAD_PARAMETER Invalid parameter.

Note: The difference between le_wifiClient_SetPreSharedKey() and this function

Parameters

[in]	accessPointRef	WiFi Access Point reference.
[in]	PassPhrase	pass-phrase for PSK

le_result_t le_wifiClient_SetPreSharedKey	(	le_wifiClient_AccessPointRef_t	accessPointRef,

void le_wifiClient_SetServerDisconnectHandler	(	le_wifiClient_DisconnectHandler_t	disconnectHandler,
		void *	contextPtr
	)

Set handler called when server disconnection is detected.

When a server connection is lost, call this handler then exit with LE_FATAL. If a program wants to continue without exiting, it should call longjmp() from inside the handler.

	)

Set the WEP key (WEP)

Returns

LE_OK Function succeeded.
LE_FAULT Function failed.

Parameters

[in]	accessPointRef	WiFi Access Point reference.
[in]	wepKey	The WEP key
