An easy way to measure the advertising interval is to download the app nRF Connect, and do a scan. The app will show the measured advertising interval. The attached image is from nRFConnect, and shows a device called Nordic-UART is advertising with a 100ms interval.

When you see N/A it means that the device has not included a device name in the advertising packet. Including a device name is optional, and if you see N/A it just means that the device doesn’t have a device name. It’s not an error.
