How to allow Bonding when a button is pressed?

[c cook]

I'm using SDK 7.1, PCA10028 eval board, SD310 2.0.1

My application has no display, and a single button for input. I want to prevent bonding until the button is pressed. Looking at Nordic's documentation I found 1 sequence chart that shows bonding, this chart seems to be for "just works" bonding. Is there a sequence chart for bonding with a static passkey?

Looking through the example projects, most have either "just works" bonding, or bonding with display and entry peripherals.

What is the best approach for this project, with regards to bonding? Do I use a static passkey (hard-coded into the firmware) and when the button is pressed load it?

Is there a good example project that does something like this?

Here it is, but this is from the S110 SoftDevice documentation.

Please have a look at this example, it implements static passkey.

Petter - I've looked at that - with my device I have only 1 button - when I set up my security parameters I have the following choices:

BLE_GAP_IO_CAPS_DISPLAY_ONLY // I don't have a display

BLE_GAP_IO_CAPS_DISPLAY_YESNO // I don't have a display - I have a "yes" button, but not a "no"

BLE_GAP_IO_CAPS_KEYBOARD_ONLY // I don't have Keyboard

BLE_GAP_IO_CAPS_NONE // "just works" but I want to require a button press

BLE_GAP_IO_CAPS_KEYBOARD_DISPLAY // I don't have a Keyboard, or a display

Which of these do I choose? I think the correct route is to set up static passkey, but I'm having problems figuring out how to make my device prevent bonding, until the button is pressed.
