[zeromq-dev] Setting an Android Device as a Subscriber

[Marcin Romaszewicz]

Subscribers by default (at least in the C++ version of ZMQ) do not
subscribe to anything. You need to call zmq_setsockopt(ZMQ_SUBSCRIBE...) to
establish a subscription. You probably have to do something similar on the
subscriber socket in jeroMQ
