This is needed in addition to <code>CONFIG_BT_MAX_CONN</code>. In addition, you should not re-start advertising in the callback, but defer it as shown for instance <a href="https://github.com/nrfconnect/sdk-nrf/blob/52eeb6a4891bbe0f0e53556d3771fb9757dc2c61/samples/bluetooth/peripheral_rscs/src/main.c">here</a> where a work queue is used.</p><div style="clear:both;"></div>
