The ZMQ SUB Message Source block receives messages from a ZMQ SUB socket and outputs async messages. This block will connect to a ZMQ PUB Message Sink or a non-GNU Radio ZMQ socket.
Parameters
(R): Run-time adjustable
- Address
- ZMQ socket address specifier. The format of the address is
tcp://*:portwhere * should be 127.0.0.1 for localhost. - Note: If the Source and Sink blocks are on two different computers on the same LAN, then the IP and port number of the Sink block must be specified on each end of that connection. For example, if the Sink is on IP 192.168.2.14:5678 and the Source is on IP 192.168.2.5, both Source and Sink blocks must specify the Sink IP and port (192.168.2.14:5678).
- Timeout
- Receive timeout in milliseconds, default is 100ms.
