Xia0 esp32c3 bt5

How do I know / make the ESP32C3 use BT5? It is a requirement of my app to use BT5 as I am making an FAA Remote ID module.

I use the DroneScanner app on my iPhone SE 3 (BT5 capable) and OpenDroneID on an old Alcatel Android.

Both phones indicate BT4 is used. How do I force / enable BT5? I’ve looked in most of the .h / .cpp library files for this.
