Create a Demo which is able to replicate in another Brick

jabrena commented 5 years ago

This is concept is inspired in Game Boy with multiplayer games: https://www.youtube.com/watch?v=HGsmLVsJVmU

The programs multi brick, should be auto configured.

Hmm, there are multiple ways how to do this. The way the software is uploaded to the brick is over SSH. We have two options:

SSH from Java - Gradle plugin bypasses Hidetake's SSH plugin and uses JSch directly (SSH.groovy, SFTP.groovy).
Alternatively, we can just use scp and ssh.

Then to establish an SSH connection, there at least two options:

Connect the bricks via WiFi/Ethernet. They can either know each other's address, or they can discover it via Avahi (though I don't know how to do that yet). The connection will already be there, so this is the easier path.
Connect the bricks via Bluetooth BNEP. The only way I know now how to do it is via graphical blueman-manager, so from my side this is not workable yet. However there might be a way how to hack through this via NetworkManager and bluetoothctl. When we have a proper Bluetooth support, we can add a similar demo for it.

There seems to be some a library for discovering via DNS-SD (=mDNS=Avahi) - https://github.com/jmdns/jmdns. Related ev3dev issue: https://github.com/ev3dev/ev3dev/issues/852
