The latest release of micro-ROS’ middleware, Micro XRCE-DDS, is out!

Micro XRCE-DDS is an implementation of the DDS-XRCE standard by the OMG, establishing a wire communication protocol for embedded devices to be integrated into the DDS global data space.

The latest release for this library, Micro XRCE-DDS v2.0.0, will be the default version for the RMW implementation of micro-ROS Galactic (out soon).

Among the main new features added:

  • Continuos fragment mode
  • Custom transports API
  • Middleware callbacks API for the Agent
  • POSIX transport based on timeout instead of polling
  • FreeRTOS+TCP transport support
  • Zephyr RTOS time functions support

… plus an updated and improved documentation!
