https://devzone.nordicsemi.com/f/nordic-q-a/34880/nrf_sdh_ble_total_link_count-vs-peripheral_link_count-and-central_link_countIn my project, I typically have 20 central connections to the Nordic device. Occasionally, I need to allow a phone to connect to the device using a peripheral link. When this occurs, I do not need the other 20 central connections to be maintained.

Hence,&nbsp;NRF_SDH_BLE_CENTRAL_LINK_COUNT +&nbsp;NRF_SDH_BLE_PERIPHERAL_LINK_COUNT &lt;= NRF_SDH_BLE_TOTAL_LINK_COUNT. So the maximum number of central link you will be able to configure with one peripheral link is 19.&nbsp;</p> <p>You can set the central link count to 20 and the peripheral link count to 0 and then modify the central and peripheral link counts at run-time when you need to connect to the device with a phone, but this will require you to reinitialize the SoftDevice.&nbsp;</p> <p>Best regards</p> <p>Bjørn&nbsp;</p><div style="clear:both;"></div>
