ESP8266 WiFi Module

Overview
7+
********
8+
9+
This example is designed to show basic usage of ESP01/ESP01S esp8266 WiFi Module on embARC board.
10+
11+
Detailed Description
12+
====================
13+
14+
* Extra Required Peripherals
15+
ESP01/ESP01S WiFi Module
16+
17+
* Design Concept
18+
Without downloading users' image, ESP01/ESP01S can be controlled using AT commands.
19+
This example is designed to show how to use AT commands to control the Wi-Fi module and exchange data.
20+
Besides, we use AT command to establish a TCP server and provide simple HTTP service just like our another example :ref:`example_net_httpserver`
21+
22+
* Usage Manual
23+
- Connect ESP01/ESP01S module to your board, see :ref:`peripheral_preparation`.
24+
- Set up an AP, the default setting of this example is to connect a WIFI with SSID: `embARC`, pwd: `qazwsxedc`.
25+
- Build, download, run the example and get log from COM port console.
26+
- When you see a `while` is shown in log, meaning that the server is setup and waiting for input. Then open your web browser (Chrome, Firefox) and visit the ip address shown in the log. You will get a web page right away.
27+
28+
Building and Running
29+
********************
30+
31+
This example outputs to the console. It is supported by all platform. The commands to run this example are as follows:
32+
33+
.. code-block:: console
34+
35+
$ cd <embarc_root>/example/freertos/esp8266_wifi
36+
$ make BOARD=emsk BD_VER=22 CUR_CORE=arcem7d TOOLCHAIN=gnu run

Once download the program to the board, you can run command ``main`` and ``lwm2m_server`` to start up a LwM2M server at default port 5683. You should also take note of server's IP address which will be used in next step. Once the server is up, run leshan client demo on your PC.
