Udp driver improvements #590
Description
The current udpdriver is a bit outdated compared to the other drivers that use seperate threads for receiving packets. I've been using a modified version of the UDP driver with a seperate thread for receivng packets in CrazySim https://github.com/llanesc/crazyflie-lib-python/tree/crazysim. Recently I modified it to have improved scanning so that CrazySim can be used with the client by scanning a range of ports for available Crazyflies. Do you think we can add this feature or a similar upgrade to the UDP driver so that CrazySim can pull directly from the latest CFLIB?
