eduroam IdPs will often (but not necessarily) configure their user devices to react to the OpenRoaming baseline RCOI:
5A-03-BA-00-00, 5A-03-BA-02-00, or 5A-03-BA-04-00 (a.k.a. "OpenRoaming for All Identities, settlement-free, no personal data requested, baseline/silver/gold QoS) - usage of the hotspot is governed by the OpenRoaming End-User Terms and Conditions

To allow your users to connect also to OpenRoaming hotspots (under the OpenRoaming End-User Terms and Conditions), firstly make sure that your users acknowledge the OpenRoaming End-User Terms and Conditions. Then configure the following two six RCOIs additionally:

5A-03-BA-80-00, 5A-03-BA-82-00, 5A-03-BA-84-00 (a.k.a. "OpenRoaming for Educational or Research Identities, settlement-free, no personal data requested, baseline QoS) - usage of the hotspot is governed by the OpenRoaming End-User Terms and Conditions
