Nordic Semiconductor has introduced nRF Join Naked Metallic, designed to supply a migration path away from the corporate’s nRF5 software program improvement equipment (SDK) and nRF52-series wi-fi systems-on-chips (SoCs) to the newest nRF54L sequence elements — and, because the title implies, it does not require a real-time working system (RTOS), although supplies an improve path to Zephyr RTOS.
“With the Naked Metallic possibility, we’re decreasing the entry barrier for creating easy Bluetooth purposes, whereas additionally providing a transparent improve path to Zephyr RTOS and the total capabilities of the nRF Join SDK for brand spanking new and current prospects,” claims Nordic Semi’s Oyvind Strom of the corporate’s launch in the present day. “This software program possibility is a significant addition that displays our aim to help a broad vary of builders and purposes. Nordic’s dedication to the world-class nRF Join SDK and the Zephyr neighborhood stays sturdy, and this technique continues to form our long-term path.”
The nRF Join SDK Naked Metallic possibility is constructed round Nordic Semi’s SoftDevice structure, and is designed to imitate the corporate’s legacy nRF5 SDK — making it simpler emigrate from older nRF52-series elements to the brand new nRF54L household of wi-fi chips. Designed for “easy” Bluetooth Low Power (BLE) purposes, it initially helps peripheral-only purposes with the promise of central- and multi-role capabilities to launch later this yr.
The Naked Metallic possibility is designed to coexist alongside the present Zephyr RTOS possibility, each throughout the nRF Join SDK and the nRF Join extension to Microsoft’s VS Code. Those that discover their tasks outgrowing the capabilities of the Naked Metallic possibility can, the corporate has confirmed, simply migrate tasks to the total Zephyr RTOS possibility — or, in the event that they select, combine their Naked Metallic purposes with third-party real-time working methods.

There is a new function to be discovered inside Naked Metallic, too, at the moment lacking from the Zephyr RTOS variant: help for a single-bank gadget firmware replace (DFU) mechanism, designed to attenuate non-volatile reminiscence utilization and go away extra space free for program code. This, Nordic Semi guarantees, might be added to the Zephyr RTOS possibility in a future launch of the nRF Join SDK.
