How do I install the AIRROBO app and connect my P20 to it?

Scan the QR code in the manual or search 'AIRROBO' in the App Store or Google Play to download the app. Create an account, log in, tap 'Add Device,' select your 2.4GHz Wi-Fi network, and enter your Wi-Fi name and password. Make sure your phone is connected to a 2.4GHz network and that Bluetooth is enabled before starting the setup process. (Page 8-9)
