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
- how you can run multiple publisher applications publishing on the same topic (n:m communication)
- 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.
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
