https://devzone.nordicsemi.com/f/nordic-q-a/43566/disable-automatic-connection-parameter-update-requestHi, I am pairing my devices with LE SC and passkey entry. I would like my connection interval to be &quot;high&quot; (upwards of 500ms) but this raises an issue. Pairing then takes approximately a minute, because of a high connection interval and many LE SMPen-USTelligent Community 13Mon, 11 Feb 2019 17:30:58 GMThttps://devzone.nordicsemi.com/thread/170452?ContentTypeID=1Mon, 11 Feb 2019 17:30:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:99429ff5-a910-424f-ae22-366d2f6e897bMateusz<p>Here&#39;s what I ended up doing.</p> <p>On the peripheral, set minimum connection interval to&nbsp;BLE_GAP_CP_MIN_CONN_INTVL_MIN, max to&nbsp;BLE_GAP_CP_MIN_CONN_INTVL_MAX and supervision timeout to BLE_GAP_CP_CONN_SUP_TIMEOUT_MAX. This results with the peripheral not sending any&nbsp;Connection Parameter Update Requests.</p> <p>On the central, connected with &quot;low&quot; connection interval. Once pairing succeeded, updated my connection parameters with&nbsp;sd_ble_gap_conn_param_update() to &quot;high&quot; values.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170416?ContentTypeID=1Mon, 11 Feb 2019 14:48:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:34ee4053-3a3e-44d6-8694-066da6c63c83Mateusz<p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/8400.Archive.zip">devzone.nordicsemi.com/.../8400.Archive.zip</a></p> <p>My initial attachments failed to upload so I zipped them up and attaching them here.</p><div style="clear:both;"></div>
