Arduino IDE for Building Compiling Environment of ESP8266

－ ESP8266 Wifi Bee (Arduino Compatible)
－ Xbee USB adapter (FTDI ready)

1. Add The Board URL to Arduino IDE
Open Arduino IDE (I am using version 1.8.0).
An installation tutorial for Arduino IDE can be found here.
Navigate to File > Preferences and click the circled button as shown below:

You should see this progress window:

After the input is completed, click OK.

2. Update the Board List

After adding the mainboard URL of ESP8266 (FireBeetle-ESP8266) to Arduino IDE, we need to update the board list, and use Arduino IDE to download ESP8266 libraries.

Open  (Tools)-> (Development board)-> (Development board manager), as shown below:

3. Install ESP8266

After completing the update, you should find FireBeetle-ESP8266 Mainboard options which you can then edit

Select “FireBeetle-ESP8266” and click “Install” (I have installed). The manager will automatically download the relevant libraries.

Wait for the install process to complete

Please Note: If you haven’t installed FireBeetle-ESP8266 mainboard you will not see the board in the list, so be sure you follow the steps above to install it first!

Entering following code:

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println("Serial Test"):
  delay(500);
}

5. Hardware Connection

Switch Wifi Bee ESP module to UART end which is the update firmware end, and insert the module on Xbee USB Adapter as shown below:

Please note the plug direction of two boards.

Set the Baud rate of download as 115200. I tried download at high Baud rate, but it always failed. Maybe FTDI chip does not support high Baud rate communication:
