I. How does it work?

The X-NODE MCU WIFI BLE (ESP32-WROOM-32) is based on the wireless SoC ESP32-WROOM-32 from Espressif Systems®, it comes with a micro USB type B connector that makes the programming of the device a simple task, it can be easily integrated in projects to enable wireless WiFi or Bluetooth communication, to connect microcontrollers, microprocessors or even industrial equipment to mobile devices or cloud services.

The X-NODE MCU WIFI BLE (ESP32-WROOM-32) is compatible with the mikroBUS™ standard, that makes it compatible with Mikroe® add-on boards ecosystem with 1000+ sensors and development boards including X-NODE devices. It also comes with two 4-pin JST connectors compatible with Sparkfun’s Qwiic connection system to expand its capabilities even further in a fast and easy way.

V. Software setup

The ESP32 module can be program with the same tools that any other Espressif SoC, therefore all development environments compatible with the ESP-IDF can be used to program the X-NODE MCU WIFI BLE (ESP32-WROOM-32). However, in order to connect to the device through the USB port the CP210x USB to UART bridge driver is needed. Once the driver is installed the device can be access through a virtual COM port.

Example with PlatformIO

Connect your X-NODE MCU WIFI BLE (ESP32-WROOM-32) device to the computer,

1. Download & install VSCode (https://code.visualstudio.com/)

2. Search the PlatformIO IDE extension.

3. Once PlatformIO it’s installed, open the project manager & create a new project.

4. Fill the project wizard with the following values and press Finish:

• Name: Test

• Board: Espressif ESP32 Dev Module

• Framework: Arduino

• Use default location.

5. This process will download the ESP-IDF toolchain, due to file sizes this may take a while the first time, please be patient and let the initialization finish.

6. When the process is finished Visual Studio Code will display the following structure.

7. Go to the official PlatformIO documentation for in depth details of the IDE usage.

Example with Arduino®IDE

1. Download & install Arduino® IDE, go to “File” > “Preferences”.

1. Copy and paste the following URL on the Additional Board field input:

https://dl.espressif.com/dl/package_esp32_index.json

1. Click on “Tools” > “Board” > “Board Manager”.

1. Search ESP32 by Espressif Systems and click on install.

1. Choose ESP32 Dev Module board.

1. Choose the COM port of the device.
