Answer 1

It would seem that you need to track which devices have already been discovered.

There are different ways to do this depending what you want to do with the information.

One example would be:

class AnyDeviceManager(gatt.Device):
    device = {}

    def device_discovered(self, device):
        if device.mac_address not in AnyDeviceManager.device:
            print("Discovered [%s] %s" % (device.mac_address, device.alias()))
            AnyDeviceManager.device[device.mac_address] = device
