DroneProxy for Parrot AR.DRone first parachute test

I have started to work on DroneProxy some time ago to work around bugs in the firmware of the drone. Basically it is a transparent proxy for the UDP AT command packets arriving on port 5556. The packets are parsed to keep track of the sequence number. If no packets are received for 1500 ms the proxy will start sending “landing” commands with increasing sequence numbers (until somebody plugs the battery…).
