(Port Busy) (Your COM port number may vary.) Something like: Error opening serial port 'COM14'. The error messages typically indicated that the COM port was busy. If you like this post probably you might like my next ones, so please support me by subscribing my blog.I was running in to a number of issues with the Arduino IDE not being able to connect to my ArduinoвЂ™s serial port. You might also find interesting trying one of these tutorials:Дo you have any questions?В Leave a comment down below! Later you can build a web server that displays that data. Now instead of sending a string saying just вЂњHI!вЂќ, you can attach sensors to your Arduino and send that data to your ESP instead. Watch the video at the beginning of this postВ for a live demonstration. This means that your Arduino is sending the string вЂњHIвЂќ and your ESP is receiving that data. Now your LED should be blinking every one second. Read this blog post for more information about lowering the voltage of signals. This works well for slow baud rates, but it might not work at fasterВ baud rates. Note: IвЂ™m using a voltage divider to shift the TX signal of the Arduino from 5V to 3.3V. Then you simply click the button Save to ESP and save your file with the name вЂњaвЂќ.В Everything that you need to worry about or change is highlighted in red box in the following Figure.ДЇollow the next schematics to complete this tutorial.

Select your FTDI programmer port (COM3, for example).

Connect your FTDI programmer to your computer.When you open the ESPlorer IDE you should see a window similar to the preceding Figure, follow these instructions to send commands to your ESP8266: Every time that receives the string вЂњHI!вЂќ at a baud rate of 9600, it will turn the GPIO 2 on or off. Summary: The ESP is configured to listen to serial communications.

Open the ESPlorer (as shown in the Figure below).Д¬opy and paste the code below into ESPlorer IDE window.

Follow these instructions to download and install ESPlorer:

I recommend using the ESPlorer IDE which is a programВ created by 4refr0ntВ to create and save Lua files into yourВ ESP8266. Having your ESP8266 flashed with NodeMCU, follow the next schematics toВ establish a serial communication between your FTDI programmer and your ESP8266 to upload some code.

Now if you open your Arduino serial monitor at a baud rate of 9600, youвЂ™ll see a message appearing in your window sayingВ вЂњHI!вЂќ every 1 second. Send Data From Arduino to ESP8266 via Serial baud rate 9600 Then in the loop() function it prints вЂњHI!вЂќ continuously every 1 second (that message will be received byВ your ESP later).Д¬opy the sketch below to your Arduino IDE and upload it to your ArduinoВ board. You begin a serialВ communication in the setup() function at a baud rate of 9600. The Arduino sketch for this tutorialВ is very simple. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price!
