message_aggregator - Man Page

Reference example UDP server




message_aggregator does not serve any useful purpose other than to demonstrate the UDP message features of WSJT-X. It is a small GUI application that interacts with any running WSJT-X instances.

Developers writing add on applications may find the source code of message_aggregator contained in the WSJT-X code repository useful. The files NetworkMessage.hpp, MessageServer.hpp, MessageClient.hpp and their associated implementations along with the application source MessageAggregator.cpp should cover all the required areas. All these files can be found at:

message_aggregator may also be used as a multi-cast UDP server which allows multiple instances of message_aggregator to be run concurrently, to do this simply use a suitable multi-cast group address in message_aggregator and in WSJT-X in the "Settings→Reporting→UDP Server" pane e.g. or ff03::1 for a local scope group.

Note that on some systems it may be necessary to add a static multi-cast route to the routing table before multi-cast traffic can be routed to sockets on the same host as the sender.
