What is a BLE Scan Request?

Hi,

I'm working with a BLE device manufacturer on a new device for which I'm tasked with developing the iOS app.

The hardware developer told me: "In response to a Scan request (from a phone or other device) the BLE stack is configured to include a device identifier". The device identifier is something I need to see in the advertising packet before I connect to the device.

I don't know what a "Scan request" is. Is this something I have to specifically ask for in my app? Is it something iOS does automatically?

Thanks, Frank
