 ## Overview
 
-The Arduino Opta™ is a powerful micro PLC device that has many features, allowing you to customize its use for your solution. Among these features are the standard connectivity features: Wi-Fi®, Ethernet and Bluetooth®. Please note that these connectivity features are not available on all variants of the Arduino Opta™. In this tutorial we will go through how to use these features with the Arduino IDE and the Arduino Opta™.

 ## Instructions
 
 ### Setup With the Arduino IDE
 
-Using the Arduino IDE we can easily work with the connectivity features, which have their own libraries that we can make use of. Make sure the latest version of the Arduino IDE is installed. The IDE can be downloaded [here](https://www.arduino.cc/en/software).

-Then we need to install the appropriate core for the Arduino Opta. Go to **Tools > Board > Boards Manager**, in the board's manager section search for **Opta mbed** and install it. For more detailed instructions on setting up the Arduino Opta with the Arduino IDE, have a look at the [Getting started with opta™ tutorial](/tutorials/opta/getting-started).

 ### Wi-Fi®
 
-The files necessary for using the Wi-Fi® on the Arduino Opta are included in the core. To try it out, we can go to **File > Examples**, and under **Examples for Opta**, we can find the **WiFi** section. Inside there is an example sketch called **WiFiWebClient**. Open this example sketch and fill out the WiFi details in the **arduino_secrets.h** tab. The sketch will make the Arduino Opta® connect to the desired website defined within `char server[] = "example.com";` variable. If the connection is successful, it will then print the website's HTML content to the serial monitor. If the sketch ran successfully, the output should look like the image below.

 ### Ethernet
 
-The Arduino Opta has an RJ45 ethernet port with a LED that will indicate the status of the connected cable. The files necessary for using Ethernet with the Arduino Opta are included in the core. To try it out, we can go to **File > Examples** and under **Examples for Opta** we can find the **Ethernet** section. Inside there is an example sketch called **WebClient**. Connect the Ethernet cable to the Arduino Opta and upload the example. This example will function the same way as the one mentioned in the Wi-Fi® section. The device will connect to the website defined in the sketch and print the website's HTML content in the serial monitor. If the sketch ran successfully, the output should look like the image below.

 ### Modbus TCP Via Ethernet Port
 
-The Arduino Opta can be configured to use Modbus TCP protocol, which runs a Modbus protocol layered over a TCP/IP stack. Thus the coverage distance is dependent on the capacity of the Ethernet cable. In the case of an industrial environment, a good cable choice could be an RJ45 cable with the category Cat6 or Cat6A allowing a maximum distance of 100 meters.

 ### Bluetooth® Low Energy
 
-To use the Bluetooth® Low Energy feature, you will need to download the **ArduinoBLE** library in the Arduino IDE. Go into the **library manager** and search for **ArduinoBLE**. if you can't find it, try sorting by official libraries published by Arduino. Once the ArduinoBLE library is installed, let's try and run a simple example that scans for other Bluetooth® devices within range. The sketch will print the found devices address, local name and the advertised service UUIDs, if present. The example can be found under **File > Examples > ArduinoBLE > Central**, the sketch is called **Scan**. When the sketch is running on the Opta, the output on the serial monitor should look something like the image below.

 ### Next Steps
 
-Now that you know how to use the connectivity features of the device, have a look at our other tutorials and try to combine the different features. The Arduino Opta uses the same architecture as the Portanta H7, it could therefore be a good idea to take a look at the Portenta H7 tutorials. Such as the using your [device as a Wi-Fi® access point tutorial](https://docs.arduino.cc/tutorials/portenta-h7/wifi-access-point) or the [Bluetooth® Low Energy connectivity with a phone tutorial](https://docs.arduino.cc/tutorials/portenta-h7/ble-connectivity).
