The default TX power with the softdevice is the same with the default TX power in the radio TXPOWER register which is 0x00 (0dbm). That means that the default TX power of 0 dBm is used.</span></p> <p><span>-Amanda&nbsp;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/329216?ContentTypeID=1Mon, 13 Sep 2021 12:00:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a0645de1-62fc-4298-8ed9-fb7acb8b5432Maheshwar<p>Thanks for reply,</p> <p>is it documented anywhere?&nbsp;</p> <p>can you point to any file / header located in sdk folder that confirms it is 0dbm by default.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/328773?ContentTypeID=1Thu, 09 Sep 2021 10:53:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9baff073-9eef-4611-8085-a452bf2a29e6Amanda Hsieh<p>Hi,&nbsp;</p> <p><span>The default TX power with the softdevice is the same with the default TX power in the radio TXPOWER register which is 0x00 (0dbm).&nbsp; It can be set by using&nbsp;<a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s113.api.v7.3.0/group___b_l_e___g_a_p___f_u_n_c_t_i_o_n_s.html#gad10e80ba20ddab42d1753fd1be2d8c26">sd_ble_gap_tx_power_set</a>&nbsp;().&nbsp;</span></p> <p><span>Regards,&nbsp;<br />Amanda</span></p><div style="clear:both;"></div>
