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.

https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide

1. Download and install the Arduino IDE (at least v1.8.8)
2. Start Arduino IDE
3. In your 'Preferences', add https://www.adafruit.com/package_adafruit_index.json as an 'Additional Board Manager URL'
4. Restart Arduino IDE
5. Open the 'Boards Manager' from Tools -> Board menu and install 'Adafruit nRF52 by Adafruit' 0.11.0 version (latest tested) - for more information check the releases notes https://github.com/adafruit/Adafruit_nRF52_Arduino/releases
6. Once the Board SUpport Package (BSP) is installed, select 'Adafruit Bluefruit nRF52 Feather' from Tools -> Board menu, which will update your system config to use the right compiler and settings for the nRF52.
7. Select the latest bootloader e.g. "0.2.11 SoftDevice s132 6.1.1".
8. This project uses "Adafruit NeoPixel by Adafruit" library, download it via the IDE: "Tool > Manage Libraries...". As of today we are using the version 1.2.3.

The Adafruit nRF52 BSP includes a python wrapper for Nordic's nrfutil, which is used to flash boards. Go into the BSP folder (hardware/Adafruit/Adafruit_nRF52_Arduino/tools/nrfutil-0.5.2), and run the following to make this available to the Arduino IDE:

$ cd ~/Library/Arduino15/packages/adafruit/hardware/nrf52
$ cd tools/nrfutil-0.5.2
$ sudo pip install -r requirements.txt
$ sudo python setup.py install
$ sudo ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/nrfutil /usr/local/bin/nrfutil

Nota : Don't install nrfutil from the pip package (ex. sudo pip install nrfutil). The latest nrfutil does not support DFU via Serial, and you should install the local copy of 0.5.2 included with the BSP via the python setup.py install command above.
