https://devzone.nordicsemi.com/f/nordic-q-a/117810/setting-appropriate-ble-event-length-with-kconfigHello, I am currently on a project where we have 4 BLE peripheral devices equipped with NRF52840 connecting to one BLE Central, which is an app on iOS or Android. From time to time the peripherals need to send a higher amount of data to the centralen-USTelligent Community 13Wed, 08 Jan 2025 11:10:46 GMThttps://devzone.nordicsemi.com/thread/517447?ContentTypeID=1Wed, 08 Jan 2025 11:10:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:077bda12-6e2b-4d15-b00c-80fc828d1c20Kenneth<p>Hi,</p> <p>My mistake in the second thread you link to, think I have fixed it now, but quickly commenting here also:</p> <p>1. I think the intention was that setting&nbsp;<span>BT_CTLR_SDC_MAX_CONN_EVENT_LEN_DEFAULT_OVERRIDE=y will&nbsp;allow to update &quot;override&quot; default CONFIG_BT_CTLR_SDC_MAX_CONN_EVENT_LEN_DEFAULT=something. Though, on second look I can&#39;t seem to find any reference to&nbsp;BT_CTLR_SDC_MAX_CONN_EVENT_LEN_DEFAULT_OVERRIDE in code or examples, and after asking internally I don&#39;t think the setting&nbsp;BT_CTLR_SDC_MAX_CONN_EVENT_LEN_DEFAULT_OVERRIDE=y actually does anything, I think it might have been used for some internal testing at some point. So as you already indicate, just setting&nbsp;BT_CTLR_SDC_MAX_CONN_EVENT_LEN_DEFAULT is sufficient.</span></p> <p><span>2.&nbsp;They should affect both roles yes.</span></p> <p><span>Sorry for the confusion,<br />Kenneth</span></p> <p><span></span></p><div style="clear:both;"></div>
