Welcome to the nRF Connect SDK!¶

The nRF Connect SDK is where you begin building low power cellular IoT applications with LTE-M and NB-IoT on the nRF9160. It offers a range of application samples and reference implementations, as well as a full suite of device drivers for the nRF9160 SiP. The nRF Connect SDK includes the Zephyrâ„¢ real-time operating system (RTOS), which is built for connected low power products.


The nRF Connect SDK contains references and code for Bluetooth Low Energy devices in the nRF52 Series, though product development on these devices is not currently supported with the nRF Connect SDK.

Documentation for different versions of the nRF Connect SDK is available at the following links:
