The HCI&nbsp;applications simply include the Bluetooth Controller and expose an HCI interface, according to the&nbsp;Bluetooth spec.</p> <p>You can enable Peripheral mode by setting these Kconfigs and all their dependencies to the suitable values:</p> <p>On both the nRF9160 Bluetooth host and nRF52840 with Bluetooth Controller + HCI:</p> <p><a href="https://docs.nordicsemi.com/bundle/ncs-2.8.0/page/kconfig/index.html#CONFIG_BT_PERIPHERAL">CONFIG_BT_PERIPHERAL<br /></a><a href="https://docs.nordicsemi.com/bundle/ncs-2.8.0/page/kconfig/index.html#CONFIG_BT_MAX_CONN">CONFIG_BT_MAX_CONN</a>&nbsp;</p> <p>On only the&nbsp;<span>nRF52840 Bluetooth Controller + HCI:</span></p> <p><a href="https://docs.nordicsemi.com/bundle/ncs-2.8.0/page/kconfig/index.html#CONFIG_BT_CTLR_SDC_PERIPHERAL_COUNT">CONFIG_BT_CTLR_SDC_PERIPHERAL_COUNT</a>&nbsp;</p> <p>Hieu</p><div style="clear:both;"></div>
