Great hardware deserves great software
nRF Connect SDK
Great hardware deserves great software. We offer the nRF Connect SDK for the nRF53 and nRF52 Series. The nRF Connect SDK is a complete software development kit for Thread, Bluetooth LE, and Zigbee. It integrates the scalable Zephyr RTOS, OpenThread, and Bluetooth LE stacks. We also included a variety of samples, hardware drivers, and more.
OpenThread is an open-source implementation of the Thread networking protocol. We provide it as a pre-compiled, pre-certified library. This allows for Thread certification by inheritance, and in full source code to ease product development. For the nRF Connect SDK we have ported the lower layers of our SoftDevices. This enables the best-in-class interoperability you know our SoftDevices for. The result is the SoftDevice Controller. A SoftDevice is a wireless protocol stack that complements our SoCs. We provide them as qualified, precompiled binary files.
nRF5 SDKYou can still use the nRF5 SDK for Thread and ZigBee for our nRF52 Series SoCs. Be aware that only the nRF Connect SDK is in active development. For all new products we recommend the nRF Connect SDK.
