The ESP8266 is a microcontroller developed by Espressif Systems. Known as a WiFi module, this microcontroller can be used to perform various WiFi-related activities, with applications in home automation and beyond. Ranging in price and features, there are many types of ESP8266 modules available – but all are incredibly useful in the IoT world.
Regardless of the IoT application you’ve developed, there are two ways to connect your ESP8266 to the cloud. First, you can input your WiFi credentials in the ESP8266’s firmware to establish the required connection and start sending data. A second way – which we’ll cover step-by-step below – is by building your own access point into the board, creating a universal firmware that will establish a connection to any available network with just the press of a button.
Requirements
Step 1. Hardware setup
Note: The Ubidots team made some modifications in the ConfigManager Library to implement a routine that launches the AP mode by simply pressing an external reset button.
Depending on the ESP8266 module you choose, you may need to assign the reset pin using this library version. The default button settings are assigned to PIN 5; if using a NodeMCU, you must connect the button into the D1 pin.
Step 2. Set up the Arduino IDE with your device
Before using any ESP8266 device, you’ll have to install the boards into the Arduino IDE. Follow the steps below to compile the board.
If you haven’t already, start by downloading the Arduino IDE.
- Open the Arduino IDE. Select Files -> Preferences and enter the URL below the Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
NOTE: If you’re a Mac user, Arduino and File contain different drop-down functions compared to Windows users. You’ll also need to install the following driver to upload firmware to your NodeMCU.
2. Open the Boards Manager from Tools -> Board -> Boards Manager and install the ESP8266 platform. To find the correct device, search for ESP8266 within the search bar.
3. Select the ESP8266 module you’re using. In this case, we decided to use the NodeMCU 1.0 (ESP-12 Module). To select the board, go to Tools > Board > Select the board.
Additionally, to communicate with the NodeMCU, we’ll also need to select the port com. Go to Tools -> Port and select the appropriate PORT for your device.
To keep everything running fast and smooth, let’s make sure the upload speed is optimized to 115200. Go to Tools -> Upload Speed -> 115200.
4. Head over to GitHub and download the ConfigManager library. Click the green button labeled “Clone or download” and select “Download ZIP“.
5. Now, go back in the Arduino IDE and click Sketch -> Include Library -> Add .ZIP Library.
Serial To Ethernet
6. Select the .ZIP file of ConfigManager and then “Accept” or “Choose”.
If successful you’ll see the following message in the Arduino IDE: 'Library added to your library. Check 'Include Library' menu'
7. Next, go to Sketch/Program -> Include Library -> Library Manager and install the PubSubClient library. To find the correct library, search PubSubClient within the search bar.
8. Now, reboot the Arduino IDE prior to upload.
9. Once you have the ESP8266 platform and required libraries installed, install the Arduino ESP8266 filesystem uploader. Follow all the repository’s installation steps and return to this guide.
10. After your uploader is installed, create a new sketch to work in and save it. Our example is called AP_ESP8266:
11. Next, go to the sketch directory and create a new folder called data.
12. Once the directory is created, download this HTML file and attached it to the directory. This file will be used in the file system.
13. Next, we need to upload the file to the ESP8266 flash file system. To begin, make sure you have selected a board port and closed Serial Monitor.
14. Select Tools > ESP8266 Sketch Data Upload to start uploading files to the ESP8266 flash file system.

When done, the IDE status bar should display SPIFFS Image Uploaded:
15.Now, paste the below code in the Arduino IDE. Once pasted, assign your desired device and variable labels, as well as your unique Ubidots TOKEN. If you don’t know your Ubidots TOKEN, find out how to get one here.
Copy and paste the below code into the Arduino IDE, including your specific device and variable parameters.
16. After inputting your parameters, verify the code within the Arduino IDE. To do this, click the checkmark icon in the top left corner of your Arduino IDE.
Then, upload your code into your NodeMCU. Choose the right-arrow icon beside the checkmark.
Once the code is uploaded, you’ll see the below message in the Arduino IDE:
Your ESP8266 module is now ready to establish a connection with any available network by just pressing the button!
17. To verify the connection status, open the Serial monitor, press the button connected to your ESP module and hold it for 5 seconds until you see the message “Starting Access Point” in your serial monitor:
18. Now that the Access Point is created, you can establish connection from your phone. Under Wi-Fi networks, select Ubidots Access Point:
When the connection is established, it will redirect you to the page below. Input your Wi-Fi parameters and click save.
19. To verify the connection is established, go to the Serial Monitor:
Now, return to your Ubidots accounts to visualize the data received from your new device:
Results
By following this guide, you’ll set up an Access Point that connects your device to any available network without setting the credentials into the firmware – thus creating a universal firmware that can be used anywhere!
