Function Documentation

le_data_ConnectionStateHandlerRef_t le_data_AddConnectionStateHandler	(	le_data_ConnectionStateHandlerFunc_t	handlerPtr,
		void *	contextPtr
	)

Add handler function for EVENT 'le_data_ConnectionState'

This event provides information on connection state changes

Parameters

[in]	handlerPtr
[in]	contextPtr

le_result_t le_data_AddRoute ( const char *LE_NONNULL ipDestAddrStr )

Add a route on the data connection service interface, if the data session is connected using the cellular technology and has an IPv4 or IPv6 address.

Returns

LE_OK on success
LE_UNSUPPORTED cellular technology not currently used
LE_BAD_PARAMETER incorrect IP address
LE_FAULT for all other errors

Note

Limitations:

only IPv4 is supported for the moment
route only added for a cellular connection

Parameters

[in] ipDestAddrStr The destination IP address in dotted format

void le_data_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_result_t le_data_DelRoute ( const char *LE_NONNULL ipDestAddrStr )

Delete a route on the data connection service interface, if the data session is connected using the cellular technology and has an IPv4 or IPv6 address.

Returns

LE_OK on success
LE_UNSUPPORTED cellular technology not currently used
LE_BAD_PARAMETER incorrect IP address
LE_FAULT for all other errors

Note

Limitations:

only IPv4 is supported for the moment
route only removed for a cellular connection

Parameters

[in] ipDestAddrStr The destination IP address in dotted format

void le_data_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.

int32_t le_data_GetCellularProfileIndex ( void )

Get the cellular profile index used by the data connection service when the cellular technology is active.

Returns

Cellular profile index

le_result_t le_data_GetDate	(	uint16_t *	yearPtr,
		uint16_t *	monthPtr,
		uint16_t *	dayPtr
	)

Get the date from the configured server using the configured time protocol.

Warning: An active data connection is necessary to retrieve the date.

Returns

LE_OK on success
LE_BAD_PARAMETER if a parameter is incorrect
LE_FAULT if an error occurred

Parameters

[out]	yearPtr	UTC Year A.D. [e.g. 2017].
[out]	monthPtr	UTC Month into the year [range 1...12].
[out]	dayPtr	UTC Days into the month [range 1...31].

bool le_data_GetDefaultRouteStatus ( void )

Get the default route activation status for the data connection service interface.

Returns

true: the default route is set by the data connection service
false: the default route is not set by the data connection service

le_data_Technology_t le_data_GetFirstUsedTechnology ( void )

Get the first technology to use

Returns

One of the technologies from le_data_Technology_t enumerator if the list is not empty
LE_DATA_MAX if the list is empty

le_data_Technology_t le_data_GetNextUsedTechnology ( void )

Get the next technology to use

Returns

One of the technologies from le_data_Technology_t enumerator if the list is not empty
LE_DATA_MAX if the list is empty or the end of the list is reached

le_data_Technology_t le_data_GetTechnology ( void )

Get the technology currently used for the default data connection

Returns

One of the technologies from le_data_Technology_t enumerator
LE_DATA_MAX if the current technology is not set

Note: The supported technologies are LE_DATA_WIFI and LE_DATA_CELLULAR

le_result_t le_data_GetTime	(	uint16_t *	hoursPtr,
		uint16_t *	minutesPtr,
		uint16_t *	secondsPtr,
		uint16_t *	millisecondsPtr
	)

Get the time from the configured server using the configured time protocol.

Warning: An active data connection is necessary to retrieve the time.

Returns

LE_OK on success
LE_BAD_PARAMETER if a parameter is incorrect
LE_FAULT if an error occurred

Parameters

[out]	hoursPtr	UTC Hours into the day [range 0..23].
[out]	minutesPtr	UTC Minutes into the hour [range 0..59].
[out]	secondsPtr	UTC Seconds into the minute [range 0..59].
[out]	millisecondsPtr	UTC Milliseconds into the second [range 0..999].

void le_data_Release ( le_data_RequestObjRef_t requestRef )

Release a previously requested data connection

Parameters

[in] requestRef Reference to a previously requested data connection

void le_data_RemoveConnectionStateHandler ( le_data_ConnectionStateHandlerRef_t handlerRef )

Remove handler function for EVENT 'le_data_ConnectionState'

Parameters

[in] handlerRef

le_data_RequestObjRef_t le_data_Request ( void )

Request the default data connection

Returns

Reference to the data connection (to be used later for releasing the connection)
NULL if the data connection requested could not be processed

le_result_t le_data_SetCellularProfileIndex ( int32_t profileIndex )

Set the cellular profile index used by the data connection service when the cellular technology is active.

Returns

LE_OK on success
LE_BAD_PARAMETER if the profile index is invalid
LE_BUSY the cellular connection is in use

Parameters

[in] profileIndex Cellular profile index to be used

void le_data_SetServerDisconnectHandler	(	le_data_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.

le_result_t le_data_SetTechnologyRank	(	uint32_t	rank,
		le_data_Technology_t	technology
	)

Set the rank of the technology used for the data connection service

Returns

LE_OK if the technology is added to the list
LE_BAD_PARAMETER if the technology is unknown
LE_UNSUPPORTED if the technology is not available

Parameters

[in]	rank	Rank of the used technology
[in]	technology	Technology

le_result_t le_data_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.
LE_UNAVAILABLE if the server is not currently offering the service to which the client is bound.
LE_NOT_PERMITTED if the client interface is not bound to any service (doesn't have a binding).
LE_COMM_ERROR if the Service Directory cannot be reached.
