https://devzone.nordicsemi.com/f/nordic-q-a/70606/ble---default-power-dbmHi, I&#39;m using nrf52840 with BLE functionality. I don&#39;t use sd_ble_gap_tx_power_set in my application. Does it mean that I&#39;m using default power (dbm)? What is the default power?

If you do not use the sd_ble_gap_tx_power_set function the SoftDevice will use the TXPOWER&#39;s default value.</p> [quote user=""]What is the default power?[/quote] <p><a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fradio.html&amp;anchor=register.TXPOWER">The default value of the RADIO peripherals TXPOWER register is 0x0</a>, which corresponds to 0 dBm.<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
