SimpleLinkFatalErrorEventHandler()

void SimpleLinkFatalErrorEventHandler

(

SlDeviceFatal_t *

fatal_err_event

)

SimpleLinkFatalErrorEventHandler.

This handler gets called whenever a driver error occurs requiring restart of the device in order to recover.

SimpleLinkGeneralEventHandler()

void SimpleLinkGeneralEventHandler

(

SlDeviceEvent_t *

dev_event

)

SimpleLinkGeneralEventHandler.

This handler gets called whenever a general error is reported by the NWP / Host driver. Since these errors are not fatal, the application can handle them.

Note

See the CC3120/CC3220 NWP programmer's guide (SWRU455) section 17.9.

SimpleLinkHttpServerEventHandler()

void SimpleLinkHttpServerEventHandler	(	SlNetAppHttpServerEvent_t *	http_event,
		SlNetAppHttpServerResponse_t *	http_resp
	)

SimpleLinkNetAppEventHandler()

void SimpleLinkNetAppEventHandler

(

SlNetAppEvent_t *

netapp_event

)

SimpleLinkNetAppEventHandler.

This handler gets called whenever a Netapp event is reported by the host driver / NWP.

Note

See the CC3120/CC3220 NWP programmer's guide (SWRU455) section 5.7.

SimpleLinkNetAppRequestEventHandler()

void SimpleLinkNetAppRequestEventHandler	(	SlNetAppRequest_t *	netapp_request,
		SlNetAppResponse_t *	netapp_response
	)

SimpleLinkNetAppRequestMemFreeEventHandler()

void SimpleLinkNetAppRequestMemFreeEventHandler

(

SimpleLinkSockEventHandler()

void SimpleLinkSockEventHandler

(

SlSockEvent_t *

psock

)

SimpleLinkWlanEventHandler()

void SimpleLinkWlanEventHandler

(

SlWlanEvent_t *

wlan_event

)

SimpleLinkWlanEventHandler.

This handler gets called whenever a WLAN event is reported by the host driver / NWP.

Note

See the CC3120/CC3220 NWP programmer's guide (SWRU455) sections 4.3.4, 4.4.5 and 4.5.5.
