https://devzone.nordicsemi.com/f/nordic-q-a/65181/how-to-change-passkey-by-using-press-a-buttonHi, I&#39;m super rookie on BLE project, my question is how can I using button press to accept a central pairing instead of typing passkey, here&#39;s my code, using nrf 52810, ble_app_hrs example for my studyen-USTelligent Community 13Fri, 28 Aug 2020 13:22:10 GMThttps://devzone.nordicsemi.com/thread/267021?ContentTypeID=1Fri, 28 Aug 2020 13:22:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9140af55-694e-441d-baa7-3453c3f4ca4eVidar Berg<p>Hello,</p> <p>I think <span><a title="Experimental: LE Secure Connections Multirole Example" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.0/ble_sdk_app_multirole_lesc.html?cp=7_1_4_2_1_3">Experimental: LE Secure Connections Multirole Example </a></span><span>supports numeric comparison pairing. Please take a look at to see if you can use it as a reference. One problem I noticed while looking through the code you posted is that the IO capabilities are not set to BLE_GAP_IO_CAPS_DISPLAY_YESNO. You may also find the Softdevice MSCs here useful even though most of it is handled by the Peer Manager module:&nbsp; <a title="Peripheral Security Procedures" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v7.0.1/group___b_l_e___g_a_p___p_e_r_i_p_h___s_e_c___m_s_c.html?cp=4_7_3_1_2_1_5_10">Peripheral Security Procedures</a></span></p><div style="clear:both;"></div>
