This repository contains the Arduino BSP for Adafruit Bluefruit nRF52 series:

• Seeed XIAO BLE
• Seeed Wio node

There are two methods that you can use to install this BSP. We highly recommend the first option unless you wish to participate in active development of this codebase via Github.

1. Download and install the Arduino IDE (At least v1.6.12)
2. Start the Arduino IDE
3. Go into Preferences
4. Add https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json as an 'Additional Board Manager URL'
5. Restart the Arduino IDE
6. Open the Boards Manager from the Tools -> Board menu and install 'Seeed nRF52'
7. Once the BSP is installed, select 'Seeed nRF52840' from the Tools -> Board menu, which will update your system config to use the right compiler and settings for the nRF52.

This core is based on Arduino-nRF5 by Sandeep Mistry, which in turn is based on the Arduino SAMD Core.

The following libraries are used:

• FreeRTOS as operating system
• LittleFS for internal file system
• nrfx for peripherals driver
• TinyUSB as usb stack
