I am having a hard time setting the TX power to the maximumen-USTelligent Community 13Tue, 09 Sep 2025 08:06:27 GMThttps://devzone.nordicsemi.com/thread/548157?ContentTypeID=1Tue, 09 Sep 2025 08:06:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a5968ea-bd27-4e80-b131-d74018535c7fKenneth<p>Hi,</p> <p>Can you try to set&nbsp;<br /><a href="https://docs.nordicsemi.com/bundle/ncs-2.4.4/page/kconfig/index.html#CONFIG_BT_CTLR_TX_PWR_PLUS_3">https://docs.nordicsemi.com/bundle/ncs-2.4.4/page/kconfig/index.html#CONFIG_BT_CTLR_TX_PWR_PLUS_3 = y<br /></a></p> <p>For guidance on coded phy check out:<br /><a href="https://docs.nordicsemi.com/bundle/ncs-2.4.4/page/nrf/samples/bluetooth/central_hr_coded/README.html">https://docs.nordicsemi.com/bundle/ncs-2.4.4/page/nrf/samples/bluetooth/central_hr_coded/README.html</a>&nbsp;<br /><a href="https://docs.nordicsemi.com/bundle/ncs-2.4.4/page/nrf/samples/bluetooth/peripheral_hr_coded/README.html">https://docs.nordicsemi.com/bundle/ncs-2.4.4/page/nrf/samples/bluetooth/peripheral_hr_coded/README.html</a>&nbsp;</p> <p>When you say implanted, I assume you are aware that 2.4GHz&nbsp;works really poorly in human body since it&#39;s mostly of water and thereby absorbed, so the range will be very short.</p> <p>Kenneth</p><div style="clear:both;"></div>
