https://devzone.nordicsemi.com/f/nordic-q-a/17844/how-to-use-one-static-passkey-in-the-central-and-peripherical-devicesHi, I&#39;ve read a lot of question on the forum, but I&#39;m a lit bit confused about what I have to do to use one static passkey on the central and peripherical device. In my first tests I&#39;ll use two PCA10040 with S132, so i dont have keyboard or displayen-USTelligent Community 13Tue, 22 Nov 2016 14:29:40 GMThttps://devzone.nordicsemi.com/thread/68783?ContentTypeID=1Tue, 22 Nov 2016 14:29:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:81a51852-81b6-4f23-a355-c82a68dd5f1arcfr<p>Thanks for the fast response, Petter.

See <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v3.0.0/group___b_l_e___g_a_p___p_e_r_i_p_h___b_o_n_d_i_n_g___s_t_a_t_i_c___p_k___m_s_c.html?cp=2_3_0_1_0_2_1_3_8_7_1">this</a>. Then you should set that you have a display.</li> <li>On the central you should then set that you have keyboard. You should receive the BLE_GAP_EVT_AUTH_KEY_REQUEST event when you pair, and reply with the static passkey with sd_ble_gap_auth_key_reply().
