|
|
|
* The WiFi driver can be consider as black box, it knows nothing about the high layer code, such as
|
|
|
|
|
* TCPIP stack, application task, event task etc, all it can do is to receive API call from high layer
|
|
|
|
|
* or post event queue to a specified Queue, which is initialized by API esp_wifi_init().
|
2016-09-07 08:33:13 -04:00
|
|
|
|
*
|
|
|
|
|
* The event task is a daemon task, which receives events from WiFi driver or from other subsystem, such
|
|
|
|
|
* as TCPIP stack, event task will call the default callback function on receiving the event. For example,
|
|
|
|
|
* on receiving event SYSTEM_EVENT_STA_CONNECTED, it will call tcpip_adapter_start() to start the DHCP
|
2016-09-12 04:43:32 -04:00
|
|
|
|
* client in it's default handler.
|
|
|
|
|
*
|
|
|
|
|
* Application can register it's own event callback function by API esp_event_init, then the application callback
|
|
|
|
|
* function will be called after the default callback. Also, if application doesn't want to execute the callback
|
|
|
|
|
* in the event task, what it needs to do is to post the related event to application task in the application callback function.

|
|
|
*
|
2016-09-12 04:43:32 -04:00
|
|
|
|
* The application task (code) generally mixes all these thing together, it calls APIs to init the system/WiFi and
|
2016-09-07 08:33:13 -04:00
|
|
|
|
* handle the events when necessary.
