https://devzone.nordicsemi.com/f/nordic-q-a/13374/send-passkey-from-central-to-peripheralI want to implement static passkey based bonding, using the nrf51822 on both sides[Central is not a Mobile phone].My sw for peripheral side is working with a mobile device.But in the actual applkication i have to use a nrf51822 chip.The host controlleren-USTelligent Community 13Thu, 21 Apr 2016 11:48:32 GMThttps://devzone.nordicsemi.com/thread/51002?ContentTypeID=1Thu, 21 Apr 2016 11:48:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7141ffe8-044c-40e5-9b30-df94d3451139Petter Myhre<p>Then I guess you say that you have a display on the peripheral, and you have set a static passkey. If that is the case you should say that you have a keyboard on the central. Then you will get the BLE_GAP_EVT_AUTH_KEY_REQUEST event, and you need use the static passkey in the reply sd_ble_gap_auth_key_reply().

Then you will get the BLE_GAP_EVT_AUTH_KEY_REQUEST event on both sides. And you reply with the same passkey on both sides with sd_ble_gap_auth_key_reply().</p><div style="clear:both;"></div>
