Nordic Semiconductor has introduced nRF Join Naked Metallic, designed to offer a migration path away from the corporate’s nRF5 software program improvement package (SDK) and nRF52-series wi-fi systems-on-chips (SoCs) to the newest nRF54L collection elements — and, because the identify implies, it would not require a real-time working system (RTOS), although gives an improve path to Zephyr RTOS.
“With the Naked Metallic choice, we’re decreasing the entry barrier for creating easy Bluetooth functions, whereas additionally providing a transparent improve path to Zephyr RTOS and the total capabilities of the nRF Join SDK for brand new and present prospects,” claims Nordic Semi’s Oyvind Strom of the corporate’s launch at the moment. “This software program choice is a significant addition that displays our objective to help a broad vary of builders and functions. Nordic’s dedication to the world-class nRF Join SDK and the Zephyr neighborhood stays robust, and this technique continues to form our long-term route.”
The nRF Join SDK Naked Metallic choice 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 Vitality (BLE) functions, it initially helps peripheral-only functions with the promise of central- and multi-role capabilities to launch later this 12 months.
The Naked Metallic choice is designed to coexist alongside the prevailing Zephyr RTOS choice, each inside 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 choice can, the corporate has confirmed, simply migrate tasks to the total Zephyr RTOS choice — or, in the event that they select, combine their Naked Metallic functions with third-party real-time working programs.

There is a new function to be discovered inside Naked Metallic, too, at present lacking from the Zephyr RTOS variant: help for a single-bank gadget firmware replace (DFU) mechanism, designed to reduce non-volatile reminiscence utilization and depart more room free for program code. This, Nordic Semi guarantees, can be added to the Zephyr RTOS choice in a future launch of the nRF Join SDK.
Extra data on the nRF Join SDK Naked Metallic choice is out there on the Nordic Semi web site; a technical introduction is out there on the corporate’s developer zone weblog.
