ESP8266 Serial-to-WIFI Module

SKU: TEL0092

Wifi Bee-ESP8266 is a Serial-to-WIFI module using XBEE design in a compact size, compatible with XBEE expansion base, applicable to a variety of 3.3V single-chip system. It can be used for Arduino, wireless data transfer, remote control. On-board switch can be used to easily select the Startup module or Upgrade firmware. ESP8266 has a powerful on-chip processing and storage capacity, built-in 32-bit processor, built-in Lwip protocol stack. Support AP+STA mode co-exist. And you could configure various parameters via AT commands.

    • 1. Usage and Firmware Update Guide

    This comprehensive guide covers the usage and firmware update instructions for the ESP8266 module, including connection to access points, TCP client modes, problem troubleshooting, and the update process using ESP_Flasher.

    2. How to Enter AT Mode

    This guide explains how to enter AT mode using an ESP8266 module and a USB-Serial adapter, detailing steps like inserting the ESP8266, opening the Arduino IDE Monitor, and sending the AT command to enable module control.

    3. Usage Example for Arduino-LED Control

    This is a little application which is built on the **4.1.2 2 TCP_Client_Single** trail, if you have finished that part, you could upload the sketch below, and send commands "H","L" to open up or turn off it on your computer. And since that almost every Arduino card has a LED built on board, connected with D13, so in the sketch, I will use it as the target LED.

    FAQ

    • Can I program this with ONLY the XBee shield or is the USB adapter (FTDI) also necessary in addition to the XBee shield?

      Hi everyone! I have a problem with a Wifi Bee: sending some official ESP8266 AT commands (among which AT+PING, AT+RESTORE, AT+CWJAP_CUR...) I get an ERROR as the only reply. I have been suggested a tutorial to flash the command set, but I still don't have all the AT commands working (some more, some less than before). I've tried with another brand new WiFi Bee to make sure I did not screw something during my first attempts, but the issue is confirmed. What can I do? Thank you!
