How to trace IPTables in RHEL7 / CENTOS7

If you are debugging IPTables, it is handy to be able to trace the packets while it traverses the various chains. I was trying to find out why port forwarding from the external NIC to a virtual machine attached to a virtual bridge device was not working. You need to perform the following preparations: Load […]

IoT – Smart Gateway with Intel Edison & TI Sensortag – Part 1

A dear colleague of mine provided me with a Texas Instruments Sensortag Unfortunately this present was connected with the request to get it running with my Intel Edison and the Smart Gateway. This blog will be part one of my endeavor. Update the Intel Edison My Intel Edison still runs the old firmware, so the […]

RHMAP BPM-Mobile-App – IoT Demo

In this blog I would like to demonstrate how easy it is to develop a mobile app with AngularJS and NodeJS. The goal is to develop the app locally and build an Android application with RHMAP later on. ‘RHMAP’ stands for ‘Red Hat Mobile Application Plattform‘. Maybe you know it as ‘FeedHenry’. What’s the target […]

Building an IoT Sensor with Node-RED on Intel Edison

This blog will cover my first experiments with an Intel Edison, a small Computer-on-Module, which Intel was so kind to give to me! Thanks again for this guys! There are many websites explaining how to setup your development computer to work with an Intel Edison, like Intels own website. So I will assume you have followed […]

Implementation of SmartGateway for IoT Demo

This is part 5 of my IoT series of blogs. So far we did look at the following topic Introduction into the planned scenario Building a Raspberry Pi based Smart Gateway ESP8266 and DHT22 based smart sensor Putting the Smart into the Smart IoT Device Setting up an “all in one” demo environment This post will […]

All in One IoT Demo with JBoss Fuse, BPM Suite and BRMS

This is part 5 of my IoT series of blogs. So far we did look at the following topic Introduction into the planned scenario Building a Raspberry Pi based Smart Gateway ESP8266 and DHT22 based smart sensor Putting the Smart into the Smart IoT Device In this blog we will create a first running version of […]

Building the IoT Smart Gateway with Docker, Raspberry Pi and JBoss for the “lazy” ones – Ansible rules!

If you have followed my earlier posts, then you know, that I’m in the process of building an IoT Demo, with a Raspberry Pi2  as the Smart Gateway. During this process, I had to re-install my Raspberry multiple times, but after the second time I got a bit tired of doing the same steps over […]

Putting the Smart into the Smart IoT Device

This is part 4 in my IoT series of blogs. The first parts did cover the following topics: Introduction into the planned scenario Building a Raspberry Pi based Smart Gateway ESP8266 and DHT22 based smart sensor This blog will describe how to enable the Smart Gateway to handle, enhance and forward incoming messages. As for […]

ESP8266 and DHT22 based smart sensor

This is part 3 in my IoT series of blogs. The first parts did cover the following topics Introduction into the planned scenario Building a Rasperry Pi based Smart Gateway In this article I will describe how I build my first physical sensor, based on an ESP8266 microprocessor and a DHT22 digital temperature and humidity sensor. […]

Building a Raspberry Pi based Smart Gateway for IoT

As described in my previous post, my intention is to create a new version of my IoT Demo. The first element that I wanted to get up and running is the Gateway, which is supposed to run a MQTT broker to receive and forward messages a transformation capability to change messages, enable smart routing of […]
