2.2.3 SUITABLE FIRMWARE

We would also need to download (or prepare) firmware compatible with the ESP8266 board.

The best idea is to download the latest NONOS SDK from the official web-site of "Espressif Systems" - it

contains a folder with pre-built binaries. Download and extract the latest version of "ESP8266 NONOS

SDK" from the official Espressif web-site. The archive is usually located under the "SDKs & Demos" sub-

group at the web-page with the ESP8266EX resources. By the time of writing this document, the location

is:

http://espressif.com/en/products/hardware/esp8266ex/resources

We used "ESP8266 NONOS SDK v1.5.0" during the preparation of this document. If you want to have the

exact same behavior as us, use "ESP8266 NONOS SDK v1.5.0". You can download it from here:

https://www.olimex.com/Products/IoT/_resources/esp8266_nonos_sdk_v1.5.1_16_01_08_0.rar

You can also use our custom IoT firmware files that are available at GitHub:
