Tool 

Description 

SEGGER Embedded Studio 

SEGGER Embedded Studio is an easy-to-use integrated development 
environment with project management tools, editor and debugger supporting 
ARM Cortex devices. Full debug support including Real Time Terminal (RTT) 
output is also available. Available for Windows, macOS, and Linux. 
Free license for use with the Nordic nRF5 ICs and modules:  
http://license.segger.com/Nordic.cgi  

SEGGER J-Link Software and 
Documentation Pack 

J-Link Commander (JLink.exe) is a command line-based utility that can be used 
for verifying proper functionality of J-Link as well as for simple analysis of the 
target system. It supports some simple commands, such as memory dump, halt, 
step, go etc. to verify the target connection. Available for Windows, macOS, and 
Linux. 

Nordic Semiconductor SDK 

The nRF5 SDK is your first stop for building fully featured, reliable and secure 
applications with the nRF52 and nRF51 series. It offers developers a wealth of 
varied modules and examples right across the spectrum including numerous 
Bluetooth Low Energy profiles, Device Firmware Upgrade (DFU), GATT serializer 
and driver support for all peripherals on all nRF5 Series devices.  
SDKs for Bluetooth Mesh, Thread, Zigbee and other protocols are also available. 

Nordic Semiconductor  
nRF Connect for Desktop 

nRF Connect is a cross-platform tool that enables testing and development with 
Bluetooth® low energy (previously called Bluetooth Smart). It allows easy setup of 
connections with other devices and uses these connections to read and write the 
external nodes. Available for Windows, macOS, and Linux. 

Nordic Semiconductor  
nRF Connect for Mobile 

nRF Connect for Mobile, previously known as nRF Master Control Panel, is a 
powerful generic tool that allows you to scan and explore your Bluetooth low 
energy devices and communicate with them. nRF Connect for Mobile supports 
several Bluetooth SIG adopted profiles, as well as the Device Firmware Update 
profile (DFU) from Nordic Semiconductor or Eddystone from Google. Available for 
iOS and Android. 

Nordic Semiconductor 
Mobile Apps 

Additional mobile utilities for your application development. Available for iOS and 
Android.
