https://devzone.nordicsemi.com/f/nordic-q-a/6853/where-is-initial-value-of-transmit-power-in-nrf51822Hi I am trying to change the radio&#39;s transmit power in program, but I can&#39;t solve it. I downloaded nRF51822 Beacon v1.1.0. and am testing PCA20006. (Source Code\nrf51_beacon\ble_app_beacon\pca20006) I am making an admin program for iOS7 deviceen-USTelligent Community 13Mon, 04 May 2015 04:15:04 GMThttps://devzone.nordicsemi.com/thread/24148?ContentTypeID=1Mon, 04 May 2015 04:15:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3e1f8d5c-84a3-4b88-8649-22c0f5cb6917RK<p>Initial value for the S110 is 0dB.

And if I remember correctly default value is 0.</p><div style="clear:both;"></div>
