/* Notes about WiFi Programming
|
*
|
* The esp32 WiFi programming model can be depicted as following picture:
|
*
|
*
|
* default handler user handler
|
* ------------- --------------- ---------------
|
* | | event | | callback or | |
|
* | tcpip | ---------> | event | ----------> | application |
|
* | stack | | task | event | task |
|
* |-----------| |-------------| |-------------|
|
* /|\ |
|
* | |
|
* event | |
|
* | |
|
* | |
|
* --------------- |
|
* | | |
|
* | WiFi Driver |/__________________|
|
* | |\ API call
|
* | |
|
* |-------------|
|
*
|
* 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().
|
*
|
* 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
|
* 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.
|
*
|
* The application task (code) generally mixes all these thing together, it calls APIs to init the system/WiFi and
|
* handle the events when necessary.
