This new version include the next improvements:
- Improvement of the 6lowpan stack and interoperability with Linux 6lowpan stack.
- ADC support.
- DAC support.
- And all the NuttX 7.29 improvements which you can see here: [NuttX 7.29 version](https://bitbucket.org/nuttx/nuttx/downloads/nuttx-7_29-README.txt)

title: micro-ROS temperature publisher demo release
author: jfm92

This demo shows a use case in which one micro-ROS client publishes temperature value from a sensor using a micro-ROS bridge as a gateway to ROS2.
To run this demo, we will use an Olimex-STM32-E407 board with an HIH6130 temperature/humidity sensor and Raspberry Pi which works as a bridge.
The Olimex board runs a micro-ROS client, in this client, we will bring-up a node and a topic, and it will publish the measured value of the sensor.
At the same time, the Olimex board is connected by serial to a Raspberry Pi, which is running a micro-ROS agent. This micro-ROS agent will act as a gateway to the ROS2 world, publishing this topic and making it visible from any device which runs ROS2 in the same network.

The next video shows this demo running.
