Bonding with io capabilities

[A_Caron]

Hi everyone,

I'm developping on nRF52840 with SDK 15.0.0 and Softdevice S140 v6.0.0

I'm using Peer Manager for pairing and bonding.

Everything work fine with io_caps BLE_GAP_IO_CAPS_NONE and implicit bonding.

Now I want to add user action for bonding validation.
I have one led and one button so I changed io_caps to BLE_GAP_IO_CAPS_DISPLAY_YESNO
But I can't figure out when light up the led and which function to call on button click ?

Is there any tutorial similar to this scenario ?

Thanks you for your time !

Here is the message sequence chart for the softdevice. You need to handle the BLE_GAP_EVT_PASSKEY_DISPLAY event.
