https://devzone.nordicsemi.com/f/nordic-q-a/63859/okay-to-omit-connection-parameter-negotiationHello, The BLE peripheral I&#39;m developing does not have any specific required connection parameters. I understand that the central ultimately controls the selection of parameters and the peripheral can only request certain parameters. I&#39;d like to been-USTelligent Community 13Fri, 17 Jul 2020 19:55:57 GMThttps://devzone.nordicsemi.com/thread/260664?ContentTypeID=1Fri, 17 Jul 2020 19:55:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28586d69-0ad4-4133-b7f0-1a2cc7f3081bTim<p>Thanks Hung.

The peripheral can request connection parameters but it&#39;s the central who decides which connection parameter should be used.&nbsp;</p> <p>If you don&#39;t want any negotiation from the peripheral you can just skip the ble_conn_params.c library.&nbsp;<br /><br />The &quot;negotiation&quot; in the library is simply that if the connection parameter doesn&#39;t match with what the peripheral wants it will try to request again and again. After 3 times AFAIK, the peripheral will disconnect (optional).&nbsp;</p><div style="clear:both;"></div>
