How to Program the Adafruit Feather nRF52 Bluefruit LE Board in Ubuntu

The Adafruit Feather nRF52 Bluefruit LE is a powerful and versatile board that combines a Bluetooth Low Energy (BLE) module with an ARM Cortex M4F microcontroller. It can be programmed using the Arduino IDE or other tools, but in this article we will focus on how to program it in Ubuntu, a popular Linux distribution.

Before we start, we need to make sure we have some prerequisites installed on our Ubuntu system. We will need:

The Arduino IDE version 1.8.13 or higher. You can download it from here or install it using the snap package manager.

The Adafruit nRF52 board support package. You can install it using the Arduino IDE's Board Manager, following the instructions here.

The Adafruit Bluefruit Connect app for your smartphone or tablet. You can download it from Google Play or App Store. This app will allow us to communicate with the board via BLE.

A USB cable to connect the board to your computer.

A 3.7V LiPo battery to power the board (optional).

Once we have everything ready, we can proceed with the following steps:

Connect the board to your computer via USB. You should see a new device appear in /dev/ttyACM0 (or similar). If not, make sure you have the correct drivers installed.

Launch the Arduino IDE and select Tools -> Board -> Adafruit Bluefruit nRF52 Feather.

Select Tools -> Port -> /dev/ttyACM0 (or whatever port your board is connected to).

Open an example sketch from File -> Examples -> Adafruit Bluefruit nRF52 Libraries -> Peripheral -> blinky.

Click on the Upload button to compile and upload the sketch to the board. You should see a red LED blinking on the board.

Open the Adafruit Bluefruit Connect app on your smartphone or tablet and scan for nearby devices. You should see a device named \"Bluefruit52\" appear on the list. Tap on it to connect.

Select Controller -> Control Pad from the app menu. You should see a screen with four buttons: 1, 2, 3 and 4.

Press any of the buttons and observe how the red LED on the board changes its blinking pattern according to the button pressed.

Congratulations! You have successfully programmed the Adafruit Feather nRF52 Bluefruit LE board in Ubuntu and communicated with it via BLE. You can now explore other examples and features of this board, such as sensors, UART, SPI, I2C, etc. For more information, check out the Adafruit Feather nRF52 Bluefruit LE Learning Guide. aa16f39245
