Communication between Windows DDS Micro and Embedded Board

Hi all,

It will be really great if someone could answer my questions, because I have been trying to get the communication working successfully between my Windows PC and Embedded Board using Connext DDS Micro 3.0.0.

Any kind of help will be more than appreciated to get the communication working between my Embedded Board(Publisher) and my Windows PC(Subscriber) for HelloWorld_dpde example in C.

I am using Connext DDS Micro 3.0.0 and trying to communicate between Windows 7 machine and an ARM based Real Time Architecture microcontroller board with FreeRTOS and lwIP.

Understand Addressing between DDS and Transport layer



I have been going through the C documentation for Connext DDS Pro 5.3.1 and have been trying to understand the addressing mechanism that DDS uses for service discovery and the way in which it communicates with underlaying Transport layer.


1. What is the difference between rtps_instance_id and participant id?

2. In the documentation, they refer to GUID as (GUID Prefix + Entity ID). Is this Entity ID same as the participant_id ?
