https://devzone.nordicsemi.com/f/nordic-q-a/56870/cca-on-nrf52833Hiya, We&#39;re running a few experiments with a wireless-mesh protocol based on rapid flooding on a few nrf52833 dev kits. We&#39;d ideally like to use a channel contention mechanism (think RTS/CTS from UART) but we&#39;re finding the turn around time of theen-USTelligent Community 13Thu, 23 Jan 2020 14:14:26 GMThttps://devzone.nordicsemi.com/thread/230658?ContentTypeID=1Thu, 23 Jan 2020 14:14:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5906d78a-738e-4249-8161-a391c1959bb2Simonr<p>Thank you for clarifying. No, that won&#39;t be possible I&#39;m afraid. The radio must be powered on in order to generate any kind of signal.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/230625?ContentTypeID=1Thu, 23 Jan 2020 13:38:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:01457e0e-0a36-4007-906a-ee102300c3b0jamesadevine<p>I would like to know if it is possible to generate a carrier signal and have other nordic chips sense the presence of the carrier without powering up the transmitter.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/230597?ContentTypeID=1Thu, 23 Jan 2020 12:39:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cf3cabba-1ba0-46ca-a04e-aa543a1ef29bSimonr<p>Hi</p> <p>I&#39;m sorry, but what exactly are you asking here? It seems like you want something like the Bluetooth Mesh functionality. We have an SDK for Bluetooth Mesh available. You can find both the <a href="https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_mesh_latest.html">downloadable files and documentation on the Infocenter.</a></p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
