 ## Portenta and Low Energy Bluetooth®
-The onboard Wi-Fi/Bluetooth® module of the H7 offers low energy Bluetooth® functionality that gives the board the flexibility to be easily connected to devices which also support Bluetooth® Low Energy such as the Arduino Nano 33 IoT or most modern smart phones. Compared to classic Bluetooth®, Low Energy Bluetooth® is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range.

 ## Instructions
 
 ### Configuring the Development Environment
-To communicate with the Portenta H7 via Bluetooth®, we are going to start by uploading a pre-built sketch that starts a Bluetooth® network and allows your mobile device, which will be used to control the LEDs, to connect to it. The sketch uses the [ArduinoBLE](https://www.arduino.cc/en/Reference/ArduinoBLE) Library that enables the Bluetooth® Low Energy module and handles important functions such as scanning, connecting and interacting with services provided by other devices. You will also be using a third party application (e.g. [nRF Connect](https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Connect-for-mobile)), running on your mobile device that will connect your device to the board and help you control the built-in LED.

 ### 1. The Basic Setup
 
-Begin by plugging in your Portenta board to the computer using a USB-C cable and open the Arduino IDE or the Arduino Pro IDE. If this is your first time running Arduino sketch files on the board, we suggest you check out how to [set up the Portenta H7 for Arduino](setting-up-portenta) before you proceed.

 ### 2. Install the ArduinoBLE Library 
 
-You will need to install the ArduinoBLE library in the Arduino IDE you are using. For this example we will use the classic Arduino IDE. To install the library go to : **Tools > Manage Libraries...** type **ArduinoBLE** and click **Install**. Make sure you install ArduinoBLE version 1.1.3 or higher.

 ### 3. Create the Bluetooth® Low Energy Sketch
 
-Let's program the Portenta with the following example sketch. If the Bluetooth® Low Energy module can be initialized correctly, you will see the blue LED lighting up for one second after uploading the sketch. If it fails you will see the red LED lighting up instead. Copy and paste the following code into a new sketch in your IDE or by downloading the [Arduino_Pro_Tutorials](https://github.com/arduino-libraries/Arduino_Pro_Tutorials) from the Arduino IDE and open it from: **Examples > Arduino_Pro_Tutorials > BLE Connectivity on Portenta H7 > PortentaBLE**

-In our example we use a pre-defined Bluetooth® number code pre-setup for controlling a device's LEDs. This code can also be referred to as [GATT codes](https://www.bluetooth.com/specifications/gatt/services/), which define how two Bluetooth® low energy devices transfer data. Once a connection is established with a device, its respective GATT code, which is a 16 bit identifier, is stored in a lookup table for future reference.

 ### Next Steps
 
-Now that you learnt how to configure the Portenta as a Bluetooth® Low Energy endpoint you can try with two Portentas (or other Bluetooth® Low Energy capable Arduino devices) to facilitate bidirectional communication. More information on how to achieve that can be found on the [BLE library reference page](https://www.arduino.cc/en/Reference/ArduinoBLE).

 ## Troubleshooting
 
 ### Sketch Upload Troubleshooting
-If you try to upload a sketch and receive an error message, saying that the upload has failed you can try to upload the sketch while the Portenta H7 is in bootloader mode. To do so you need to double click the reset button. The green LED will start fading in and out. Try to upload the sketch again. The green LED will stop fading when the upload completes.
