@ldab

maybe you can add this to iOS too?

[ldab]

Once it is added it will apply to both systems, it’s just the Bluetooth pairing stuff, I can look at it but @jakkra probably knows the API by heart

it should be just passkey_display callback in bt_conn_auth_cb()

Have implemented a rough demo

But needs some adjustments in the BLE implementation to make it good.
