https://devzone.nordicsemi.com/f/nordic-q-a/99719/how-does-the-nrf52820-use-the-gazell-protocolHi all: I want to use Gazell protocol as the wireless communication protocol for my USB dongle. The SDK has nRF52840&#39;s Gazell example. And When I ported it to my nRF52820 project, the following error occurred: .\_build\nrf52820_xxaa.axf: Error: L6367Een-USTelligent Community 13Tue, 16 May 2023 07:43:37 GMThttps://devzone.nordicsemi.com/thread/425779?ContentTypeID=1Tue, 16 May 2023 07:43:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8195b138-2392-49b9-946b-7e30f4b37b45Mark_Y<p>Thanks！</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/425585?ContentTypeID=1Mon, 15 May 2023 11:29:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b929e4d6-68af-45b6-af56-d90949d96c63Sigurd<p>Hi,</p> <p>We don&#39;t have support for Gazell for nRF52820 in nRF5 SDK.</p> <p><span>In nRF Connect SDK/nrfxlib, there is a&nbsp;</span><a href="https://github.com/nrfconnect/sdk-nrfxlib/tree/v1.9.1/gzll/lib/nRF52811/soft-float">library built for nRF52820 (with soft-float)</a><span>. This would be the only current solution for a production quality Gazell library for nRF52820. If you are starting a new project, it may be beneficial to start out with nRF Connect SDK anyway, as this is the platform that will have active development going forward. nRF5 SDK is still maintained, but it will not get new features.</span></p> <p><a href="https://github.com/nrfconnect/sdk-nrf/tree/main/samples/gazell">https://github.com/nrfconnect/sdk-nrf/tree/main/samples/gazell</a></p><div style="clear:both;"></div>
