The specification says that the minimum commissioning time (bdbcMinCommissioningTime) should be set to 180 secs, so I don&#39;t find it wise to change that either.</p> [quote user=""]&nbsp; 2. I want to change the open time (default is 180s) to 60s, but it likes not work. is there any API to change it ?[/quote] <p>If you anyways want to change the bdbcCommissioningTime I recommend you take look at the permit join request (Mgmt_permit_joining_req) in the BDB specification and function <a href="https://infocenter.nordicsemi.com/topic/sdk_tz_v4.0.0/group__zdo__mgmt.html?cp=7_3_5_1_2_5_40#ga96503ced1d17f9986b98666791169699">zb_zdo_mgmt_permit_joining_req</a>.</p> <p>Best regards,</p> <p>Marjeris</p> <p>&nbsp;</p><div style="clear:both;"></div>
