Passkey Generation

[Gilson]

Hello 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, Gil

Hi Gilson,

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.

[update 2014-07-02] With the latest softdevice www.nordicsemi.com/.../S110-SoftDevice-v7.0 you will be able to set a static passkey.

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.

Thanks much
