ESP8266 Ping Test Demonstration

This guide is intended to help users run ping test on the ESP8266 easily and quickly. It demonstrates the testing of network connectivity by running ping test in Station mode or SoftAP mode of ESP8266. The ping test has been demonstrated and run on the ESP-Launcher. However, with appropriate build settings, the test can be made to run on any ESP8266-based system.

ESP8266 RF Performance Test Demonstration

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.

ESP-Launcher Data Send and Receive Operation Power Consumption Tests

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.

ESP8266 FOTA Demonstration

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. However, with appropriate build settings based on your application flash configuration, the test can be made to run on any ESP8266-based system. The demonstration initially runs the user1.bin as the primary firmware. The user1.bin, when executed, connects to the update server and downloads user2.bin (updated firmware) into the flash memory. When a system restart is triggered, the ESP8266 boots into the updated user2.bin, which now becomes the primary firmware binary file until another update is available for download. This new update is downloaded as user1.bin. This cycle is repeated for every subsequent update.

ESP8266 FOTA Demonstration with Phone App

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. However, with appropriate build settings based on your application flash configuration, the test can be made to run on any ESP8266 based system.
