https://devzone.nordicsemi.com/f/nordic-q-a/92513/how-to-disconnect-disable-ble-peripheral-zephyrI have a use case where a Peripheral requires to disconnect itself from the Central. Is this possible? I have tried using the peripheral_hr example and modified as follows https://github.com/vChavezB/peripheral_disconnect/blob/main/main.c I amen-USTelligent Community 13Mon, 03 Oct 2022 13:39:11 GMThttps://devzone.nordicsemi.com/thread/389014?ContentTypeID=1Mon, 03 Oct 2022 13:39:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5423a1c5-2af6-45d4-8384-d5238859504fVidar Berg<p>Thanks for updating your ticket. Yes, you need to select one of the listed disconnect reasons (<a href="https://github.com/nrfconnect/sdk-zephyr/blob/f252fac960bf2806bf66815f292b5586c38b9f34/include/zephyr/bluetooth/conn.h#L516">link</a>), and&nbsp; BT_HCI_ERR_REMOTE_USER_TERM_CONN is usually the one you want if you just want to terminate a connection.</p> [quote userid="117198" url="~/f/nordic-q-a/92513/how-to-disconnect-disable-ble-peripheral-zephyr/388868"]The disable error seems to be that the NRF52833 DK does not support the api bt_disable[/quote] <p>Yes, you are right. The disable API is supported by the BT host, but not our controller. That is why it returns with -ENOTSUP / -134. But are you sure you need to disable the stack in your case? In most cases it is sufficient to stop or pause ongoing BLE tasks such as advertising.</p> <p></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/388868?ContentTypeID=1Sat, 01 Oct 2022 18:28:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:731b542e-409c-440f-8b4d-2f85147d0faavcbz<p>Ok I think I solved it.<br />Disconnection error reason needs to be BT_HCI_ERR_REMOTE_USER_TERM_CONN as mentioned in another post and in the zephyr API docs.<br />The disable error seems to be that the NRF52833 DK does not support the api bt_disable</p><div style="clear:both;"></div>
