The default TX power is indeed 0dBm by default.</p> <p>2. The TX power in NCS applications should be set with&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html#CONFIG_BT_CTLR_TX_PWR"><span>CONFIG_BT_CTLR_TX_PWR</span></a>&nbsp;in your prj.conf file. Here you have choices of what you set them, and for +8dBm you need to use&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html#CONFIG_BT_CTLR_TX_PWR_PLUS_8">CONFIG_BT_CTLR_TX_PWR_PLUS_8</a>.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
