Is there anything we can do about robots broadcasting on port 48002?


Release : 20.3

Component : UIM - ROBOT


There are a couple things to check on here.

1. UIM hubs will broadcast to find other hubs;

2. UIM Robots will broadcast to find secondary hubs in certain circumstances.

For hubs, you can disable this functionality by changing "Broadcast On" in the Settings/General tab of the hub GUI:

Or you can add/change the following in hub.cfg, in the main <hub> section:

broadcast_on = no

For robots, whether they broadcast to find a secondary hub is controlled by the checkbox "Search the subnet for a secondary hub..." in the controller config.

The raw configure equivalent of this is:


<controller> section

temporary_hub_broadcast = no


To search the subnet, robots broadcast a "getnearesthub" command so if you disable this checkbox or add the above key it should prevent this behavior.
