Wi-Fi
=====

Introduction
------------

The WiFi libraries provide support for configuring and monitoring the ESP8266 WiFi networking functionality. This includes configuration for:

- Station mode (aka STA mode or WiFi client mode). ESP8266 connects to an access point.
- AP mode (aka Soft-AP mode or Access Point mode). Stations connect to the ESP8266.
- Combined AP-STA mode (ESP8266 is concurrently an access point and a station connected to another access point).

- Various security modes for the above (WPA, WPA2, WEP, etc.)
- Scanning for access points (active & passive scanning).
- Promiscuous mode monitoring of IEEE802.11 WiFi packets.

Application Examples
--------------------

See :example:`wifi` directory of ESP8266_RTOS_SDK examples that contains the following applications:

* Simple application showing how to connect ESP8266 module to an Access Point - `template <https://github.com/espressif/esp-idf-template>`_.

Important
^^^^^^^^^

Since the ESP8266 RTOS SDK V3.0, we moved some functions from IRAM to flash, including `malloc` and `free` fucntions, to save more memory.
In this case, please do not read/write/erase flash during sniffer or promiscuous mode. You need to disable the sniffer or promiscuous mode at first, then read/write/erase flash.
