The Arduino IDE provides a flexible and powerful environment for programming BLOX devices using traditional code-based methods. This guide will help you get started by installing the Arduino IDE, setting up the ESP32 cores, and adding the necessary libraries.

Before getting started, ensure that you have the following:

- A computer running Windows, macOS, or Linux. - An internet connection to download the necessary software and libraries.

Download Arduino IDE 2:

Visit https://www.arduino.cc/en/software and select the appropriate version for your operating system.

Install the IDE:

Follow the installation instructions provided on the website. Once the installation is complete, launch the Arduino IDE.

Open the Arduino IDE:

Launch the Arduino IDE and navigate to `File > Preferences`.

Add the ESP32 Board URL:

In the “Additional Boards Manager URLs” field, enter the following URL:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Click “OK” to save the preferences.

Install the ESP32 Core:

Go to `Tools > Board > Boards Manager`.

In the search bar, type “ESP32” and install the latest version of the ESP32 by Espressif Systems.

Open the Library Manager:

Go to `Sketch > Include Library > Manage Libraries`.

Search for the BLOX Library:

In the Library Manager, search for “OpenBuilds BLOX”.

Click “Install” to add the library to your Arduino IDE.

Alternatively, you can install the library manually by downloading it from the https://github.com/OpenBuilds/OpenBuildsBLOX/

Select the ESP32-S3 Board:

Go to `Tools > Board` and select the ESP32-S3 Development board for your BLOX device.

Connect Your BLOX Device:

Connect the BLOX device to your computer via USB. Ensure the correct port is selected in `Tools > Port`.

Also set:

• USB CDC On Boot = Enabled
• Flash Size = 8MB (64Mb)

Upload a Sketch:

You can now write or upload a sketch to your BLOX device. Use the examples provided in the BLOX library to get started quickly. Including the OpenBuildsBLOX.h library will help you initialise all the onboard hardware with ease
