PublishHelloWorldP2P example
This example will show how to publish data creating a client publisher. It is necessary to have the following profiles enabled to compile this example:
UCLIENT_PROFILE_UDP
Usage
-
Run an agent in a certain port, for example, 2018:
MicroXRCEAgent udp4 -p 2018. -
Run the SubscriberHelloWorldP2P example or some subscriber that can read the HelloWorld topic.
-
Run the PublisherHelloWorldP2P example. The example expects first and second argument to be IP address and port where the Micro XRCE-DDS Agent is running. It can also be parameterized with the number of topics that will be sent.
If no number is given, the subscriber will listen indefinitely.
Topic
The HelloWorld topic has the following IDL representation:
struct HelloWorld
{
unsigned long index;
string message;
};
