You need to have an internet connection at the same time as being connected to the FlightScope for Awesome Golf to work. iPads only allow one WiFi connection, so this can be a problem. The easiest solution is to use an iPad which has a 4G or 5G cell/mobile data connection built-in. Some folks are able to get internet through a Bluetooth connection to their phone, but this depends on the network. Another option is to attach a compatible ethernet adapter to the iPad and connect the ethernet cable to a WiFi access point / router / network switch. It is also possible to use an ethernet connection to FlightScope models with an ethernet port, e.g. X3.
