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 ?

    I don't know wath is happening. I tried ble_app_proximity and I had the same result with . On PC I have pin code error on my and ble_app_proximity project. Maybe it is dongle blame. On Android I have PIN code request. But Pin code doesn't write. If I manually set pin code i can connect. On raspberry I can connect and disonnect but attribute missing. BLE_GAP_EVT_AUTH_STATUS never comes. Never! I use custom board on RedBear BLE nano and StLink programmer. On all devices writes that Keyboard bounded but in debug mode I see than device not bounded. Help me. I must finish project. I don't know what happenings. It is my project. I use S130 and example downloaded in pack installer Keil. www.dropbox.com/.../ble_app_hids_keyboard.zip
