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.

Returns
pointer to the new AT Command reference
le_result_t le_atClient_Delete ( le_atClient_CmdRef_t  cmdRef)

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.

le_result_t le_atClient_GetFinalResponse ( le_atClient_CmdRef_t  cmdRef,
char *  finalRsp,

le_result_t le_atClient_GetFirstIntermediateResponse ( le_atClient_CmdRef_t  cmdRef,
char *  intermediateRsp,
size_t  intermediateRspNumElements 
)

This function is used to get the first intermediate response.

Returns
  • LE_FAULT when function failed
  • 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

size_t  intermediateRspNumElements 
)

This function is used to get the next intermediate response.

Returns
  • LE_NOT_FOUND when there are no further results
  • 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

This function must be called to send an AT Command and wait for response.

Returns
  • LE_FAULT when function failed
  • LE_TIMEOUT when a timeout occur
  • 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
le_result_t le_atClient_SetCommand ( le_atClient_CmdRef_t  cmdRef,
const char *  command 
)

This function must be called to set the AT command string to be sent.

const char *  finalResp,
uint32_t  timeout 
)

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.
