Instead, they offer information and support services via a forum for those with the patience and persistence to search the maze. The developers of the IC, Espressif, have apparently chosen to not only outsource manufacturing, but also to avoid being directly involved in the line of ESP modules that utilize the ESP8266 chip. There is no shortage of information on the Web about the 8266 in fact, there may be too much.of the wrong type. The first article described using the Arduino IDE to program the ESP8266, and contains some important background information that will not be repeated here. If (wifi.This is the author's second article about the ESP8266 integrated circuit, a relatively new chip comprising a full-featured 32-bit RISC ♜ and a built-in 802.11 b/g/n Wi-Fi circuit. Wifi.begin(&Serial, &mySerial) //Serial is used to communicate with esp8266 module, mySerial is used to debug SoftwareSerial mySerial(10, 11) // RX, TXĭelay(2000) // it will be better to delay 2s to wait esp8266 module OK #define ssid "test" // you need to change it send "H" to turn ON LED send "L" to turn OFF LED Then connect a LED on Digital pin13, and open the software on PC_TCP server, send command to control the LED state: such as the esp8266 is is 192.168.1.3, and the server ip is 192.168.1.1 ,then esp8266 can connect to the server this example use esp8266 to connect to an Access Point and connect to SINGLE TCP Server which is at the same subnet 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. 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.

then Like in AT mode, but pull the swith of ESP8266 to "UART" side.Don't forget to pull it back to "BOOT" after updating firmware.Ģ Choose Firmware 3 choose serial port of esp8266, click flash to burn firmware； 4 wait for done. Please download the Firmware and Tools first.

You may have a try "Update Firmware" Update Firmware If everything is ok, but still failed connection.

The wifiBee socket on expansion shield has a loose connection to the wifi Bee.

Whether the botton on the ESP8266 is also on the left side"BOOT".

Whether the button on expansion shield was push to the left side"RUN" but not"PROG".

The wifi you are using is good, and the code ssid and password is correct.

Unplug the USB cable from Arduino to power off, and plug it again to restart module.

If the monitor print" Connect failed!" Please try/check these steps:

5 Server mode Note:Since now, the STA mode which support the Server mode is not stable, we are working on that you could refer to the ESP8266 manual book to try.

Working voltage: 3.3V power " appeared, it means ESP8266 entered into Transparent Mode which transfer data faster than normal mode.

Support for TTL serial port to wireless application.

Built-in low-power 32-bit CPU: can work as an application processor.

And you could configure various parameters via AT commands.

On-board switch can be used to easily select the Startup module or Upgrade firmware.ĮSP8266 has a powerful on-chip processing and storage capacity, built-in 32-bit processor, built-in Lwip protocol stack. It can be used for Arduino, wireless data transfer, remote control. 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.
