Roscore on minibot is not using custom hostnames (rosbridge is working fine)
When using eg. http://minibot-01.local:11311/ as hostname within the blockly webpage no communication to the minibot is possible. This problem is only within the blockly environment, setting ROS_MASTER_URI from a notebook works fine.
- TODO check mdns
Note that this works in the in the new ui so it might be not worth solving this for the old one
