From what I can see this does not set the Tx power, so the default Tx power of 0 dBm is used. You can increase it if you like, up to the limit of what is supported by the HW ( 8 dBm for the nRF52840). That is doen using <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s140.api.v6.1.1/group___b_l_e___g_a_p___f_u_n_c_t_i_o_n_s.html?cp=4_7_4_4_2_1_2_38#gad10e80ba20ddab42d1753fd1be2d8c26">sd_ble_gap_tx_power_set()</a>.</p><div style="clear:both;"></div>
