I'm trying to work with the ZQM REQ / REP message blocks while learning about ZMQ. From their overview guide < http://zguide.zeromq.org/page:all >, they define various graphs where the interconnects are the ZMQ connections.
Thus, for example, in Figure 4 "Publish-Subscribe", the PUB would be GR sinks: taking in messages / data & publishing it to a ZMQ SUB; the ZPQ SUB would be GR sources: receiving data from ZMQ SUB & pushing out message. Looking in GRC, these blocks align with my expectations. Ditto for Figure 5 "Parallel Pipeline" using ZMQ PUSH (GR sink) and ZMQ PULL (GR source). But this model doesn't work for the REP / REQ in Figure 2 "Request-Reply". I would expect the ZMQ REQ to be a GR sink but instead if is a source; likewise, I'd expect the ZMQ REP to be a GR source & it is instead a sink. The internal coding is consistent with the external naming; I just question whether the naming was swapped. Am I missing something? - MLD _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
