How to test whether the ble_app_beacon example is advertising?

[KIKI]

I am working on the nrf52840 kit with the ble_app_beacon example, compile and download the code successfully. But I don't know how to test whether the kit is advertising, I am a freshman in this field, could any guys give me some guidance? Thank you very much!

Take any BLE enabled phone, download any BLE test app from particular app store (I recommend Nordic's nRF Connect) and see what is in the air.

Thank you for your reply, I find the company ID could be used to confirm the advertisement. Thank you very much!
