Same for me too. This could very well be an issue with Ubuntu 20.04, did someone try it on a later version?

Same issue on Linux Mint 20.2, but I've found a workaround. Some devices in range probably have hidden names, so you can try to change blueP#get_bluetooth_devices() to something like this:

55        bt_devices = []
56
57        for device in devices:
58            obj = self.proxyobj(bus, device, 'org.freedesktop.DBus.Properties')
59            name = 'Unknown name'
60            try:
61            	name = str(obj.Get("org.bluez.Device1", "Name"))
62            except BaseException as e:
63            	pass
64            bt_devices.append({
65                "name": name,
66                "address": str(obj.Get("org.bluez.Device1", "Address")),
67                "port": self.get_device_port(str(obj.Get("org.bluez.Device1", "Address")))
68            })
