Introduction

A common use case is that multiple sensors are sending data of the same type, e.g. LIDAR data, and a subscriber is interested in the data of all those sensors.

This example demonstrates

  1. how you can run multiple publisher applications publishing on the same topic (n:m communication)
  2. how to communicate between C and C++

!!! info The default communication policy is many to many. If you have built iceoryx with the CMake flag -DONE_TO_MANY_ONLY this example will not run.

Run iceensemble

The easiest way is to build all examples via ./tools/iceoryx_build_test.sh. Then, create eight terminals and run one command in each of them.

./build/iox-roudi

./build/iceoryx_examples/icehello/iox-cpp-publisher-helloworld
./build/iceoryx_examples/icedelivery/iox-cpp-publisher
./build/iceoryx_examples/icedelivery/iox-cpp-publisher-untyped
./build/iceoryx_examples/iceoptions/iox-cpp-publisher-with-options
./build/iceoryx_examples/icedelivery_in_c/iox-c-publisher

./build/iceoryx_examples/icedelivery/iox-cpp-subscriber
./build/iceoryx_examples/iceoptions/iox-subscriber-with-options

Alternatively, you can use the provided tmux script.

./iceoryx_examples/iceensemble/run_iceensemble.sh

!!! info As iox-subscriber-with-options requests the blocking publisher feature, although having the same capro::ServiceDescription {"Radar", "FrontLeft", "Object"} it is only connected to iox-publisher-with-options
