		void *	contextPtr
	)

Add handler function for EVENT 'le_wifiClient_NewEvent'

This event provide information on WiFi Client event changes.

Parameters

[in]	handlerPtr

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_BAD_PARAMETER if parameter is invalid.
LE_OK if the function succeeded.

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,

If an AccessPoint is not announcing it's precense, it will not show up in the scan. But if the SSID is known, a connnection can be tried using this create function. First create the AccessPoint, then le_wifiClient_Connect() to connect to it. Will fail if called while scan is running.

Returns: AccessPoint reference to the current

Parameters

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

le_result_t le_wifiClient_Delete ( le_wifiClient_AccessPointRef_t accessPointRef )

LE_BUSY if the function was called during a scan.
LE_OK if the function succeeded.

Parameters

[in] accessPointRef WiFi Access Point reference.

le_result_t le_wifiClient_Disconnect ( void )

Disconnect from the current connected WiFi Access Point.

Returns

LE_FAULT if the function failed.
LE_OK if the function succeeded.

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.

le_wifiClient_AccessPointRef_t le_wifiClient_GetFirstAccessPoint ( void )

Get the first WiFi Access Point found. Will return the Access Points in the order of found.

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

Returns

signal strength in dBm. Example -30 = -30dBm
if no signal available it will return OxFFFF

Parameters

[in] accessPointRef WiFi Access Point reference.

le_result_t le_wifiClient_GetSsid	(	le_wifiClient_AccessPointRef_t	accessPointRef,
		uint8_t *	SsidPtr,
		size_t *	SsidNumElementsPtr
	)

Note: that the SSID does not have to be human readable ASCII values, but often has.

Returns

LE_FAULT if the function failed.
LE_BAD_PARAMETER if some parameter is invalid.
LE_OK if the function succeeded.

Parameters

[in]	accessPointRef	WiFi Access Point reference.

le_result_t le_wifiClient_TryConnectService ( void )

Try to connect the current client thread to the service providing this API. Return with an error if the service is not 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.

Returns

LE_OK if the client connected successfully to the service.
