bluetooth low energy on standby mode in iOS?

I have read the docs about the BLE for iOS, and i could see that every device has its UUID instead of mac adress for the BLE.

My question ,in which there is no answer to on the docs, is- when you turn on the bluetooth on the device ( without opening any app) , so the device's bluetooth is on , what does it advertise then, and could I discover that device or get its UUID, while his bluetooth is on,but without any app that is open.

I am pretty sure that when the BLE is on, you can discover that device, or awake him, but I wonder what data can I get from him while its on without an app . (same for Android.. )

iOS does not advertise any Bluetooth Low Energy services that are visible to another iOS device without an app running. Once an app advertises a service you will see additional services available - device information, time service, battery level.

If you are using different Bluetooth hardware to scan then you may see some advertisements without an app but the reported UUID of an iOS device changes every 15 minutes for privacy reasons - See this answer - Corebluetooth, How to get a unique UUID?
