Today it took nearly a day to study ESP8266 's smartconfig function, which should be considered as standard for WiFi cloud products. This article first smartconfig operation, and later I write an article to comb the physical layer of the specific protocol.

ESP8266 WIFI module Burn write upgrade firmware http://cckyz.blog.163.com/blog/static/13706603520150282355569/ When you want to get started with the ESP8266 WIFI module burning, you must be getting a headache from a bunch of help files. And then bask in how I burn the firmware, hoping to help you to relieve the effect. :) Burn Write Step 1, connect the GPIO0 through the 1K resistor to GND 2, connect the C

One, the development environment constructs At present, most developers in China are using winxp/win7/windows xx to do MCU development. Accustomed to the development of Windows environment friends, if once a contact to the MCU need to be a Linux environment for the development of compiling, the first response is, of necessity, "concubine can not do." For example, our protagonist ESP8266 this chip, the original supply is based on Linux development (the

Recently in the WiFi module, found that the Web SDK development of little information, found a set of video tutorials, but the presenter of the lecture style is unbearable. Students interested in SDK-based development can build a development environment through eclipes on Ubuntu systems through this post.The process can be divided into two steps:1. Download and compile the SDK2, Configuration EclipesFirst, download and compile the SDKThe esp8266 SDK h

We've got 10,000 things to do every day. But don't miss a little time Learn a little bit about what the smart cloud is doing What is gokit-soc-esp8266. GOKIT-SOC-ESP8266 is the Smart Cloud (gizwits) launched the IoT Intelligent Hardware Development platform (third generation) to help traditional hardware quickly access the Internet. When the network is complete, the data can be interconnected between th

Uart-wifi Module ESP8266 Because it is only a module, not a complete development board, so you need to connect the peripheral circuit. The trial process encountered a lot of trouble, here all record. 1. Confirm Hardware Version Since the ESP8266 version has been updated, so you need to confirm the PCB version. Features: The middle four IO ports are wired to connect out. 2. Hardware connection If confirma
