https://devzone.nordicsemi.com/f/nordic-q-a/71815/increase-tx-power-in-nrf-connect-sdkHi, How can I increase TX Power in nRF Connect SDK ? I have already followed the hci_pwr_ctrl example, but I got the error &quot;Read Tx power err: -5 reason 0x00&quot; in get_tx_power() function. Thank you for helping.en-USTelligent Community 13Wed, 24 Feb 2021 10:36:46 GMThttps://devzone.nordicsemi.com/thread/295987?ContentTypeID=1Wed, 24 Feb 2021 10:36:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c8dd394d-22ca-4d88-bb95-91e2ed2be9feSimon<p>I&#39;ve provided an answer to thishere:&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/71263/nrf52820-power-control-not-working-from-samples/295985#295985">https://devzone.nordicsemi.com/f/nordic-q-a/71263/nrf52820-power-control-not-working-from-samples/295985#295985</a>&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/295341?ContentTypeID=1Fri, 19 Feb 2021 13:00:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c537b77d-df49-49cd-a382-4f7db8453d1eSimon<p>It seems like the hci_pwr_ctrl is not working with the SoftDevice Controller for some reason, only the&nbsp;<span>Zephyr BLE Controller.
