- Flashed Ubuntu image on Beaglebone, connected via ssh and uploaded udp server program
Workshop 29/05/2013, acinonyx
- Moved forward on sockets with a basic client - server example made and presented by acynonix
- Decided to use IP/UDP stack for control communication
- Made network latency tests that gave an average of 16ms over 3 hops in our lan
- Decided to abolish the, now redundant, identifying 2 bits used for serial communication
Workshop net-pre-meetup 27/05/2013, skmp
