void le_atClient_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_atClient_CmdRef_t le_atClient_Create ( void  )

This function must be called to create a new AT command.

This function must be called to delete an AT command reference.

Returns
  • LE_OK when function succeed
Note
If the AT Command reference is invalid, a fatal error occurs, the function won't return.
Parameters
[in]cmdRefAT Command
void le_atClient_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.

Note
If the AT Command reference is invalid, a fatal error occurs, the function won't return.
Parameters

)

This function must be called to automatically set and send an AT Command.

Returns
  • LE_FAULT when function failed
  • LE_TIMEOUT when a timeout occur
  • LE_OK when function succeed
Note
This command creates a command reference when called
In case of an Error the command reference will be deleted and though not usable. Make sure to test the return code and not use the reference in other functions.
If the AT command is invalid, a fatal error occurs, the function won't return.

void le_atClient_SetServerDisconnectHandler ( le_atClient_DisconnectHandler_t  disconnectHandler,
void *  contextPtr 
)

Set handler called when server disconnection is detected.

[in]timerThe timeout value in milliseconds.
le_atClient_DeviceRef_t le_atClient_Start ( int  fd)

This function must be called to start a ATClient session on a specified device.

Returns
reference on a device context
Parameters
[in]fdFile descriptor.
le_result_t le_atClient_Stop ( le_atClient_DeviceRef_t  device)

le_result_t le_atClient_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.
