RCLL Mqtt Bridge

This is a tool to wrap the communication of the rcll-refbox with a team over json via mqtt. The advantage for this is that a new team does not need to implement the protocol.

Building

The build is done via gradle, run ./gradlew build

Running

If you are using the rcll-get-started repositor to start the refbox, there is build in support for this via the environment, please take a look there. If you want to directly start it you can use a command like:
java -jar mqtt-bridge-0.1-all.jar -b tcp://localhost:1883 -k randomkey -r localhost -t GRIPS
, note that all the arguments are required. Note that if you miss an argument it will print out a usage message.

Features

Implemented:

  • Messages Refbox to Public
  • Messages Refbox to Private
  • Prepare Machines

Messages Refbox to Public/Private

Best is you use the mqtt explorer to take a look what is published where. But there are 2 large groups (public/private) which publish the messages that are received on the according refbox peer. See images below.

tion was prepared remember that this was done, then we could publish a more strong game state which does not need to be kept in the teams planning implementation but can be handled here.
