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.

As mentioned in the other thread: If you control both sides, you can set capabilities to "keyboard only" on both the initiator and responder side. This will result in both devices having to type in the same key, and these can be static if you really want to.

In the case where any of the two report that they have a display, the resulting authentication method will be passkey entry with a randomly generated code. This is according to the Bluetooth spec.

Hi Ole,

thanks for your answer. I think this is a common use case, isn't it? The CC2541 is supporting such a feature - but I want to use the Nordic chip for our product.

Is there anything you can do for us? Is there an soft device update planned with a feature like this?

Thanks in advance!

Alex

Unfortunately, there isn't currently any way to do this. You can take a look at this question for details.
