On all hosts, clone the repository

git clone git@github.com:TIERS/fabric2rosnodejs.git

On each host, bring up the network with script hostXup.sh

./hostXup.sh

On the orderer host, run the script to bring up the channel, join all peers to the channel, and deploy the chaincode

./mychannelup.sh

On the corresponding host, go to the application-javascript-ros-hostX folder and run both publisher and subscriber

node app-ros-publisher.js
