NUS Service: sdk-zephyr implementation vs sdk-nrf implementationhttps://devzone.nordicsemi.com/f/nordic-q-a/126118/nus-service-sdk-zephyr-implementation-vs-sdk-nrf-implementationHi, I’m evaluating the NUS (Nordic UART Service) as a way to stream and receive byte arrays. I’ve noticed that there are two different implementations of the NUS service: zephyr-sdk implementation https://github.com/nrfconnect/sdk-zephyr/bloben-USTelligent Community 13Tue, 16 Dec 2025 15:00:37 GMTRE: NUS Service: sdk-zephyr implementation vs sdk-nrf implementationhttps://devzone.nordicsemi.com/thread/557110?ContentTypeID=1Tue, 16 Dec 2025 15:00:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:156c3b95-9618-451c-b33f-6dc64c11dceflongo92<p>Thank you!</p> <p>I will use the nordic implementation!</p><div style="clear:both;"></div>RE: NUS Service: sdk-zephyr implementation vs sdk-nrf implementationhttps://devzone.nordicsemi.com/thread/557059?ContentTypeID=1Tue, 16 Dec 2025 09:52:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:191df132-3f3c-40cc-94d1-615dbe843612Benjamin<p>Hi Alessandro,</p> <p>It is the same BLE service and UUIDs, implemented in two different ways. <span>The difference is in how they are implemented. The Zephyr version comes from upstream Zephyr and is more generic and vendor independent. The nRF version is maintained by Nordic and is the one typically recommended.</span><br /><br />Regards,<br />Benjamin<br /><br /></p><div style="clear:both;"></div>
