https://devzone.nordicsemi.com/f/nordic-q-a/122276/nrf54l15-continuous-wave-modeHello, How can I put the nRF54L15 into continuous wave mode? And I assume after entering CW that I can freely change channels using the FREQUENCY register (0x708). Is that correct? Thanks!en-USTelligent Community 13Tue, 17 Jun 2025 18:28:13 GMThttps://devzone.nordicsemi.com/thread/539609?ContentTypeID=1Tue, 17 Jun 2025 18:28:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b57e1de6-424c-43bb-9b91-13fd2d2dbae3Asbj&#248;rn<div style="background-color:rgba(255, 255, 255, 1);border:0;color:rgba(0, 0, 0, 1);direction:ltr;font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-align:left;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">Hello Kitc,</div> <div style="background-color:rgba(255, 255, 255, 1);border:0;color:rgba(0, 0, 0, 1);direction:ltr;font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-align:left;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;"></div> <div style="background-color:rgba(255, 255, 255, 1);border:0;color:rgba(0, 0, 0, 1);direction:ltr;font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-align:left;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">I&#39;d recommend having a look at the radio_test example in our SDK:<span>&nbsp;</span><a style="border:0;margin:0;padding:0;vertical-align:baseline;" href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/peripheral/radio_test/README.html">https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/peripheral/radio_test/README.html</a></div> <div style="background-color:rgba(255, 255, 255, 1);border:0;color:rgba(0, 0, 0, 1);direction:ltr;font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-align:left;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;"></div> <div style="background-color:rgba(255, 255, 255, 1);border:0;color:rgba(0, 0, 0, 1);direction:ltr;font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-align:left;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">You can enable constant carrier and configure frequency and data rate as you need.</div> <div style="background-color:rgba(255, 255, 255, 1);border:0;color:rgba(0, 0, 0, 1);direction:ltr;font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-align:left;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;"></div> <div style="background-color:rgba(255, 255, 255, 1);border:0;color:rgba(0, 0, 0, 1);direction:ltr;font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-align:left;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">You can freely change the frequency, but changes won&#39;t take effect until you retrigger the TXEN task to start the carrier.
