For more details RTI Connext DDS Android Raraspberry Pi-demo

What problem does it solve:

1. Systems integration via platform agnostics.
2. Demonstrates systems integration and platform agnostics by linking together,
   • Different computing systems (CPU+OS) and,
   • Software application languages (C, C++, Java etc.,).
3. To exchange various types of data (i.e., Values, Events, Alarms, Commands, Streams) coordinated between publishers and subscribers over LAN and/or WAN.

Visibility into system:

• Publisher and Subscriber match analysis, debugging, host identification,
• QoS offered and requested between publishers and subscribers,
• Data and metadata exchange and communication statics, middleware and application performance, system snapshot.

Demo architecture:

Various sensors (ultrasonic/barometric) and stepper motors connected with Raspberry Pi (ARM + Linux) exchanging data with discrete platforms (x86/Win, x86/Linux, ARM/Android) and application languages (Java, C, C++ and LabView).
