This guide demonstrates the FOTA (Firmware-Over-The-Air) function for ESP8266-based devices. In particular, the guide outlines the process of upgrading ESP8266 firmware from Espressif Cloud over Wi-Fi by using our Android app. This process requires no technical skills and does not involve a PC or UART based tools. Therefore this process can be carried out by any user, including end users of ESP8266 based products. The FOTA test has been demonstrated and run on the ESP-Launcher, an ESP8266 evaluation board designed by Espressif.
Espressif provides guidelines and a sample implementation of FOTA (Firmware Over-The-Air) function to upgrade the firmware on devices powered by the ESP8266. ESP8266 device will download a new version of firmware from the update server over Wi-Fi and run it. This guide is intended to help you run a FOTA demonstration on the ESP8266 easily and quickly, with a PC acting as the local update server. The FOTA test has been demonstrated and run on the ESP-Launcher, an ESP8266 evaluation board designed by Espressif.
The power consumption of the ESP8266 depends on the PHY mode employed for sending or receiving data. In power critical applications, it is important to balance the average or burst data transfer rate as well as overall power consumption of the system.This test demonstration is intended to demonstrate the results of various power consumption tests on the ESP8266. Based on this guide, users can choose the most appropriate PHY mode and data transmission scheme for their application.
The UART passthrough mode has been provided with the AT firmware to facilitate sending of data blocks of large size and for continuous transmission of small packets of data. In the passthrough mode, the data sent by the main application processor is directly forwarded to the target networking device via a TCP or UDP connection. Here, the ESP8266 AT firmware handles the networking tasks involved. This guide is intended to help users run TCP & UDP passthrough test on the ESP8266 IOT Platform quickly to evaluate the feature with various networking configurations of the ESP8266.
This guide is intended to help you run RF performance test on the ESP8266 easily and quickly by using a Wi-Fi network tester. The firmware provided by Espressif makes it possible to set the ESP8266 Wi-Fi radio to various modes of operation and then exchange data, which can facilitate testing the RF performance on any system based on the ESP8266. In this demonstration, the process has been demonstrated using the ESP8266 demo board and the ESP-WROOM-02 module.
This guide is intended to help implement and test the available low power modes and observe the resulting current consumption of the ESP8266 easily and quickly. It demonstrates the Modem-sleep mode, Light-sleep mode, and Deep-sleep mode.
