But how and where I must set attributes or enable notification. I know that I must restore attributes from storage. But how? I read many posts about this but I can not to fix this problem. Please help me. Thank you in advance.

    I'm sorry for late response. I was on vacation.

    By default we don't have any pin code to bond with ble_app_proximity example, are you sure you test with non-modified example ? I would suggest you to take screenshot on every step you test with the nRFConnect or nRF Master Control panel application you use. A sniffer trace would be very useful.

    You only receive BLE_GAP_EVT_AUTH_STATUS if the 2 devices bond. If on Raspberry Pi you don't actively do bonding then there will be no event. How do you ignite bonding on the Raspberry ?

    Note that from SDK v10 we don't use KEIL's pack (except for CMSIS pack and device family pack). You download SDK directly from our developer.nordicsemi.com/ site.
