https://devzone.nordicsemi.com/f/nordic-q-a/124664/54l15-radio-status-shows-to-gpiohi support team, do we have any samples on how to show radio statues to gpio? when radio is on, gpio is set to high, and radio is off, gpio is set to low. waht i can think about is dppi connect event ready and event end registor to gpio, but i havenoten-USTelligent Community 13Tue, 30 Sep 2025 11:50:54 GMThttps://devzone.nordicsemi.com/thread/550157?ContentTypeID=1Tue, 30 Sep 2025 11:50:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2c1d54ec-7581-4d8f-9302-2476b3dbf46dAsbj&#248;rn<div>Hello William,</div> <div></div> <div>We don&#39;t have an example that does this exactly as you&#39;d like to see it, but we have the code example for the COEX interface or the FEM GPIO control <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/mpsl/doc/fem.html">https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/mpsl/doc/fem.html</a>&nbsp;these would give you an indication on when radio events occur and to control who get&#39;s the antenna access. There&#39;s also code for the nRF21540 DK that could be relevant in the SDK.</div> <div></div> <div>Are they using proprietary radio implementation, e.g. ESB? Then they can write to the GPIO when the access the TXEN. If they are using BLE they have to go through the MPSL.</div> <div></div> <div></div> <div>Best regards</div> <div>Asbjørn</div><div style="clear:both;"></div>
