How to get started with FreeRTOS and ESP8266 by Denis Nuțiu

Recently, I purchased a NodeMCU from AliExpress for about $4. The reason I did this was to find out what all the fuss is about with ESP8266. NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module.

The ESP8266 also has WiFi connectivity. I was very surprised when I visited the Espressif website for the ESP8266. There’s lots of documentation and resources that you can use. For example, there’s an Android application which tells your ESP8266 to connect to your WiFi. The app sends the SSID and password as packets, the ESP8266 sniffs them, and then it....
