https://devzone.nordicsemi.com/f/nordic-q-a/2765/passkey-generationHello Gentlemen, Is it possible to know the passkey before the BLE_GAP_EVT_PASSKEY_DISPLAY event? my nRF sensor is set as a display only and my central is an Android device. Thanks, Gilen-USTelligent Community 13Thu, 12 Jun 2014 13:56:33 GMThttps://devzone.nordicsemi.com/thread/10689?ContentTypeID=1Thu, 12 Jun 2014 13:56:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:93a89286-7eb8-4e85-9249-ffe24c6021d8Gilson<p>Thanks much</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/10688?ContentTypeID=1Thu, 12 Jun 2014 13:02:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e5d281d7-daf8-4e3e-863e-ea71fd4791c2P&#229;l H&#229;land<p>Hi Gilson,</p> <p>Unfortunately the passkey is randomly generated right before you receive the BLE_GAP_EVT_PASSKEY_DISPLAY event, and you can therefore not know it before you receive it.</p> <p>BR Pål</p> <p>[update 2014-07-02] With the latest softdevice <a href="http://www.nordicsemi.com/eng/Products/S110-SoftDevice-v7.0">www.nordicsemi.com/.../S110-SoftDevice-v7.0</a> you will be able to set a static passkey.</p> <p>By using the API call sd_ble_opt_set() with the structure ble_gap_opt_passkey_t, then the passkey display event will come with the passkey you set.</p><div style="clear:both;"></div>
