Adafruit nRF52 feather board [SOLVED] I am working on a project (the scenario is depicted in the attachment) involving Bluetooth Low Energy (BLE). As a master (central device) I am using the Adafruit nRF52 feather board (https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/introduction) and as slaves (peripheral devices) a pair of Adafruit nRF8001 modules (https://learn.adafruit.com/getting-started-with-the-nrf8001-bluefruit-le-breakout/pinouts?view=all#introduction). Moreover, I have to wire the nRF52 up with an Arduino Uno rev3.

I am trying to set up the very initial communication between central and peripheral devices, but if I even try to upload the blinky sketch into the nRF52 board the compiling phase returns to me the following error: 


  exec: "nrfutil": executable file not found in $PATH


Does anyone have an idea what it means? I googled a lot but I am not able to figure it out on this problem.

Thanks in advance to anyone would be able to help me!

Filippo



[EDIT] Solved: just need to install the nfrutil first, as written in https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/arduino-bsp-setup#nrfutil-os-x-and-linux-only
Step 2 solves this problem:
