nrf-udev

udev rules for nRF (Nordic Semiconductor) development kits

You probably are here because you have:

• A nRF development kit with USB support (e.g. nRF52840)
• Linux as a development environment

and one of the following problems:

• LIBUSB_ERROR_ACCESS errors when using any nRF Connect tools
• Missing permissions to read/write the serial ports at /dev/ttyACM*
• ModemManager thinks that your development kit is a modem, and sends AT commands when plugging it in

Installation

For Debian-like systems, download the latest .deb file from https://github.com/NordicSemiconductor/nrf-udev/releases. Then, install the package using the following command in a console:

sudo dpkg -i nrf-udev_1.0.1-all.deb

Caveats

These udev rules set all Nordic Semiconductor devices as readable/writable by all users. While this gets rid of the LIBUSB_ERROR_ACCESS errors with no further configuration, this also means that any user or background process can have complete access to these USB devices.

Development

This repo contains the files needed for creating a .deb package for installing the udev rules for nRF devices. To create the package in a Debian-based linux system:

dpkg-deb -b nrf-udev_1.0.1-all
