Passkey without keyboard and display

[Alex]

Hi,

I'm developing a BLE advertising sender and want to give the user the chance to change some settings of the sender with an iOS app. The user should connect/pair to the sender inside the iOS App and enter a preconfigured passkey (like 666666). After entering the passkey he should have to chance to change the passkey inside the iOS App and change other things.

I found the "BLE_GAP_IO_CAPS_DISPLAY_ONLY" property in the IO capabilities. But if I understood it correct the passkey is generated from the softdevice. Like in the "ble_app_gls" sample:

p_passkey = (char *)p_ble_evt->evt.gap_evt.params.passkey_display.passkey;

Is it possible to use "BLE_GAP_IO_CAPS_DISPLAY_ONLY" and instead of using the softdevice generated passkey using a static one? (with the possibility to change it later by the user).

Thanks in advance,

Alex

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.
