Sink the contents of a stream to a ZMQ PUB socket.
This block acts a a streaming sink for a GNU Radio flowgraph and writes its contents to a ZMQ PUB socket. A PUB socket may have subscribers and will pass all incoming stream data to each subscriber. Subscribers can be either another gr-zeromq source block 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.
- Pass Tags
- Whether sink will serialize and pass tags over the link.
- High Watermark
- High Watermark to configure the socket to (-1 => zmq's default)
Example Flowgraph
This flowgraph is a simulation of an Amplitude Modulation transmitter. It is sending the transmit signal to a ZMQ PUB Sink data socket connected to the receiver section. For complete details see Simulation_example:_AM_transmitter_and_receiver#AM_transmitter.
