[in]	handlerPtr
[in]	contextPtr

le_result_t le_atServer_Close ( le_atServer_DeviceRef_t device )

This function closes the AT server session on the requested device.

void le_atServer_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_atServer_CmdRef_t le_atServer_Create ( const char * name )

This function created an AT command and register it into the AT parser.

LE_FAULT The function failed to delete the command.
LE_BUSY Command is in progress.

Parameters

[in] commandRef AT command reference

void le_atServer_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_result_t le_atServer_GetCommandName	(	le_atServer_CmdRef_t	commandRef,
		char *	name,
		size_t	nameNumElements
	)

This function can be used to get the AT command string.

Returns

LE_OK The function succeeded.
LE_FAULT The function failed to get the AT command string.

Parameters

[in]	commandRef	AT command reference
[out]	name	AT command string
[in]	nameNumElements

le_result_t le_atServer_GetParameter	(	le_atServer_CmdRef_t	commandRef,
		uint32_t	index,
		char *	parameter,
		size_t	parameterNumElements
	)

This function can be used to get the parameters of a received AT command.

Returns

LE_OK The function succeeded.
LE_FAULT The function failed to get the requested parameter.

Parameters

[in]	commandRef	AT command reference
[in]	index	agument index
[out]	parameter	parameter value
[in]	parameterNumElements

le_atServer_DeviceRef_t le_atServer_Open ( int fd )

This function opens an AT server session on the requested device.

Returns

Reference to the requested device.
NULL if the device is not available or fd is a BAD FILE DESCRIPTOR.

Note: Make sure to duplicate (man dup) your file descriptor before opening a server session to be able to use the suspend/resume feature

Parameters

[in] fd File descriptor.

LE_OK The function succeeded.
LE_FAULT The function failed to send the intermediate response.

Parameters

[in]	commandRef	AT command reference
[in]	intermediateRsp	Intermediate rsp to be sent

le_result_t le_atServer_SendUnsolicitedResponse	(	const char *	unsolRsp,
		le_atServer_AvailableDevice_t	availableDevice,
		le_atServer_DeviceRef_t	device
	)

This function can be used to send the unsolicited response.

Returns

LE_OK The function succeeded.
LE_FAULT The function failed to send the unsolicited response.

Parameters

[in]	unsolRsp	Unsolicited rsp to be sent
[in]	availableDevice	device to send unsol rsp
[in]	device	device reference where the unsol rsp has to be sent

le_result_t le_atServer_SetDevice	(	le_atServer_CmdRef_t	commandRef,
		le_atServer_AvailableDevice_t	availableDevice,
		le_atServer_DeviceRef_t	device
	)

This function sets the device(s) where the specified AT command is available.

Returns

LE_OK The function succeeded.
LE_FAULT The function failed to set the device.

Note: If the AT command is available for all devices (i.e. availableDevice argument is set to LE_ATSERVER_ALL_DEVICES), the "device" argument is unused.

Parameters

[in]	commandRef	AT command reference
[in]	availableDevice	device available for the AT command
[in]	device	device reference where the AT command is available

le_result_t le_atServer_Suspend ( le_atServer_DeviceRef_t device )

Suspend server / enter data mode

When this function is called the server stops monitoring the fd for events hence no more I/O operations are done on the fd by the server.

Returns

LE_OK Success.
LE_BAD_PARAMETER Invalid device reference.
LE_FAULT Device not monitored

Parameters

[in] device device to be suspended

le_result_t le_atServer_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).
