Datasheet

It will take up to a few minutes to finish installing the cross-compiling toolchain and tools associated with this BSP.

The delay during the installation stage shown in the image below is normal, please be patient and let the installation

terminate normally:

Once the BSP is installed, select 'Adafruit Bluefruit nRF52832 Feather' (for the nRF52 Feathger) of 'Adafruit

Bluefruit nRF52840 Feather Express' (for the nRF52840 Feather) from the Tools -> Board menu, which will

update your system config to use the right compiler and settings for the nRF52:

2. LINUX ONLY: adafruit-nrfutil Tool Installation

adafruit-nrfutil (https://adafru.it/Cau) is a modified version of Nordic's nrfutil (https://adafru.it/vaG), which is used to flash

boards using the built in serial bootloader. It is originally written for python2, but have been migrated to python3 and

renamed to adafruit-nrfutil since BSP version 0.8.5.

Install python3 if it is not installed in your system already

$ sudo apt-get install python3

Then run the following command to install the tool from PyPi

$ pip3 install --user adafruit-nrfutil

Add pip3 installation dir to your PATH if it is not added already. Make sure adafruit-nrfutil can be executed in terminal

by running

$ adafruit-nrfutil version

adafruit-nrfutil version 0.5.3.post12

3. Update the bootloader (nRF52832 ONLY)

This step is only required on Linux, pre-built binaries of adafruit-nrfutil for Windows and MacOS are already

included in the BSP. That should work out of the box for most setups.
