UNICAST3

Runtime only resource This resource is runtime only and doesn't have any persistent configuration.

Attributes (51)

ack_threshold Send an ack immediately when a batch of ack_threshold (or more) messages is received. Otherwise send delayed acks. If 1, ack single messages (similar to UNICAST)
