Function Documentation

_i16 sl_DeviceEventMaskGet	(	const _u8	EventClass,
		_u32 *	pMask
	)

Get current event mask of the device.

Return the events bit mask from the device. In case event is masked, the device will not send that event.

Parameters

[in]	EventClass	The classification groups that the mask is referred to. Need to be one of the following: SL_DEVICE_EVENT_CLASS_GLOBAL SL_DEVICE_EVENT_CLASS_DEVICE SL_DEVICE_EVENT_CLASS_WLAN SL_DEVICE_EVENT_CLASS_BSD SL_DEVICE_EVENT_CLASS_NETAPP SL_DEVICE_EVENT_CLASS_NETCFG SL_DEVICE_EVENT_CLASS_FS
[out]	pMask	Pointer to mask bitmap where the value should be stored. Bitmasks are the same as in sl_DeviceEventMaskSet

Returns

Zero on success, or a negative value if an error occurred

_i16 sl_Start	(	const void *	pIfHdl,
		_i8 *	pDevName,
		const P_INIT_CALLBACK	pInitCallBack
	)

Start the SimpleLink device.

This function initialize the communication interface, set the enable pin of the device, and call to the init complete callback.

Parameters

[in]	pIfHdl	Opened Interface Object. In case the interface must be opened outside the SimpleLink Driver, the user might give the handler to be used in any access of the communication interface with the device (UART/SPI). The SimpleLink driver will open an interface port only if this parameter is null!
[in]	pDevName	The name of the device to open. Could be used when the pIfHdl is null, to transfer information to the open interface function This pointer could be used to pass additional information to sl_IfOpen in case it is required (e.g. UART com port name)
[in]	pInitCallBack	Pointer to function that would be called on completion of the initialization process. If this parameter is NULL the function is blocked until the device initialization is completed, otherwise the function returns immediately.

Returns

Returns the current active role (STA/AP/P2P) or an error code:

• ROLE_STA, ROLE_AP, ROLE_P2P in case of success, otherwise in failure one of the following is return:
• SL_ERROR_ROLE_STA_ERR (Failure to load MAC/PHY in STA role)
• SL_ERROR_ROLE_AP_ERR (Failure to load MAC/PHY in AP role)
• SL_ERROR_ROLE_P2P_ERR (Failure to load MAC/PHY in P2P role)
• SL_ERROR_CALIB_FAIL (Failure of calibration)
• SL_ERROR_FS_CORRUPTED_ERR (FS is corrupted, Return to Factory Image or Program new image should be invoked (see sl_FsCtl, sl_FsProgram))
• SL_ERROR_FS_ALERT_ERR (Device is locked, Return to Factory Image or Program new image should be invoked (see sl_FsCtl, sl_FsProgram))
• SL_ERROR_RESTORE_IMAGE_COMPLETE (Return to factory image completed, perform reset)
• SL_ERROR_GENERAL_ERR (General error during init)

sl_Stop

Note

Belongs to basic_api

Warning

This function must be called before any other SimpleLink API is used, or after sl_Stop is called for reinit the device

Example:

• Open interface without callback routine. The interface name and handler are handled by the sl_IfOpen routine:

  if( sl_Start(NULL, NULL, NULL) < 0 )
  {
      LOG("Error opening interface to device\n"); 
  }

  
  
• Open interface with a callback routine:

  void SimpleLinkInitCallback(_u32 status)
  {
      LOG("Handle SimpleLink Interface acording to ststus %d\n", status);
  }
              
  void main(void)

_i16 sl_Stop

(

const _u16

Timeout

)

Stop the SimpleLink device.

This function clears the enable pin of the device, closes the communication
interface and invokes the stop complete callback

Parameters

[in]

Timeout

Stop timeout in msec. Should be used to give the device time to finish any transmission/reception that is not completed when the function was called. Additional options: 0 Enter to hibernate immediately 0xFFFF Host waits for device's response before hibernating, without timeout protection 0 < Timeout[msec] < 0xFFFF Host waits for device's response before hibernating, with a defined timeout protection This timeout defines the max time to wait. The NWP response can be sent earlier than this timeout.

Returns

Zero on success, or a negative value if an error occurred

This API will shutdown the device and invoke the "i/f close" function regardless
if it was opened implicitly or explicitly.
