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.

    If you get no service discovery then the BLE_GATTS_EVT_SYS_ATTR_MISSING won't come.

    You can try to call sd_ble_gatts_sys_attr_set(NULL) when you receive _CONNECTED event.

    If you test with our ble_app_hid_keyboard do you see the same problem ?

    Yes, It is. I use your ble_app_hid_keyboard. The same problem. I tried to call sd_ble_gatts_sys_attr_set(NULL) in the _CONNECTED event. But I see the same problem. I have not many experience with bluetooth. So maybe I somewhere I made a mistake. But firstly all works fine. After reconnect I see this problem
