The nRF Connect SDK is a software development kit designed for Nordic Semiconductor’s nRF52, nRF53, nRF70, and nRF91 Series wireless devices. It integrates the Zephyr RTOS and provides a comprehensive suite of libraries, subsystems, samples, and applications to support development across Bluetooth Low Energy, Wi-Fi, cellular IoT, Thread, Zigbee, and Matter protocols. The SDK is managed using the West tool, with the sdk-nrf repository serving as the manifest repository, coordinating multiple modules and dependencies. Its modular architecture and extensive protocol support make it suitable for developing smart agriculture solutions, including wireless sensor networks, remote monitoring systems, and precision farming applications.
