https://devzone.nordicsemi.com/f/nordic-q-a/122232/54l15-using-dppi-to-link-3-peripheral-in-different-power-domainHi I am developing in 54L15. Now use DPPI to link TIMER10&#39;s PUBLISH_COMPARE[3] ---&gt; RADIO SUBSCRIBE_STOP, it works fine. Now I want to trigger a GPIO signal through GPIOTE20 SUBSCRIBE_OUT, but it cant output signal Preiously try to link RADIOen-USTelligent Community 13Mon, 16 Jun 2025 13:48:42 GMThttps://devzone.nordicsemi.com/thread/539406?ContentTypeID=1Mon, 16 Jun 2025 13:48:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e7725b26-92f5-4048-b814-0e80a1a40168Vidar Berg<p>Hi,</p> <p>Does you application support Bluetooth or use the MPSL library with another protocol? This approach would not work in that case as the Softdevice controller will clear the RADIO configuration before use. I<span>f&nbsp;you want to monitor the radio (when used by Softevice controller) you can subscribe to these channels: <a title="https://github.com/nrfconnect/sdk-nrfxlib/blob/e380532c76d5750015bc4e53d7e2e9e27ac1f3c6/mpsl/include/protocol/mpsl_dppi_protocol_api.h" href="https://github.com/nrfconnect/sdk-nrfxlib/blob/e380532c76d5750015bc4e53d7e2e9e27ac1f3c6/mpsl/include/protocol/mpsl_dppi_protocol_api.h" rel="noopener noreferrer" target="_blank">https://github.com/nrfconnect/sdk-nrfxlib/blob/e380532c76d5750015bc4e53d7e2e9e27ac1f3c6/mpsl/include/protocol/mpsl_dppi_protocol_api.h</a>.
