637 -
638 -ChirpStack has support for creating multicast-groups to which devices can be assigned. When enqueueing a downlink payload for a multicast-group, ChirpStack will analyze which gateways must be used for broadcasting to cover the complete multicast-group. This means that potentially, a single multicast downlink payload will be emitted multiple times.
639 -
640 -Multicast can be used for the following device-classes:
641 -
642 -* Class-B
643 -* Class-C
