Important

nRF Connect SDK v1.9.2-dev1 is a development tag and may be replaced by a release in the future.

The development tag contains the following updates:

  • Added workaround in sdk-zephyr for the Anomaly 160 that is affecting the nRF5340 SoC.

  • Removed calls to __WFE() in MPSL for the nRF5340 SoC, to be in line with the Errata for the Anomaly 160.

For other changes that are included in this development tag, see Changelog for nRF Connect SDK v1.9.2-dev1.

The nRF Connect SDK is where you begin building low-power wireless applications with Nordic Semiconductor nRF52, nRF53, and nRF91 Series devices.

The SDK contains optimized cellular IoT (LTE-M and NB-IoT), Bluetooth® Low Energy, Thread, Zigbee, and Bluetooth mesh stacks, a range of applications, samples, and reference implementations, as well as a full suite of drivers for Nordic Semiconductor’s devices. The nRF Connect SDK includes the Zephyr™ real-time operating system (RTOS), which is built for connected low power products.
