TechBlog:Stay up-to-date on the various technical aspects of IoT developing.

The blog is written by our tech-team with Andreas Schmidt, CTO of ThingForward. He and his crew are always happy to “talk tech” with you. If you have any questions or comments please get in touch. 

10.09.2018 An Introduction to Narrowband IoT

This blog post gives an overview of NB-IoT technology and its specifications, as well as a discussion of the reasons for choosing NB-Iot instead of current protocols. This post along with our other upcoming blog posts, will give you some additional knowledge about NB-IoT applications, hardware selection, shields and programming it for NB-IoT.


NB-IoT, also known as LTE Cat NB1, is a LPWAN technology standard that developed by 3GPP. Simply, 3GPP is a collaboration of telecommunication standards associations. The first duty of 3GPP was to make 3G technology based on GSM, after which this scope is expanded to 3G, 4G, LTE etc. technologies. NB-IoT can co-exist with 2G-3G-4G mobile networks. There are several LPWAN technologies around, and we've already been looking at some of them, e.g. LoRaWAN and SigFox. So let's try a short comparison.

22.08.2018 IoTcamp is back! Ready for new horizons in October 2018

On the 12th and 13th of October 2018 Cassini will be hosting the third IoTcamp! Taking place in Space Shack Berlin, this IoTcamp will bring attendees on an exciting expedition through the world of Internet of Things. In previous years, the IoTcamp has been one day but this year it's extended to two.

The IoTcamp welcomes explorers and creators from business, politics, media, startups and science. It offers us all the opportunity to go into new orbits during the sessions, to find new questions to ask, to discuss promising ideas.

15.08.2018 Hacking on a Pytrack GPS module

During tests with Pycom's FiPy we had some time to test the pytrack as part of a tangle-based tracking demo. Pytrack combines a GPS with an accelerometer, an SD card suitable for data logging and a jack and charger for a LiPo battery - everything included for a tracking-based application.

03.08.2018 Booting the ESP32 with Amazon FreeRTOS and Connecting it to AWS

Amazon FreeRTOS is a secure and easy to install-deploy-connect IoT operating system for micro-controllers. It is based on FreeRTOS kernel, which you have probably heard about before, and it’s extended with several software libraries for cloud connections, messaging protocols and sensor data acquisition. FreeRTOS also makes things easier when you see your messaging on the cloud, i.e. by using Amazon Greengrass. The idea of using FreeRTOS operating system will help us to simplify cloud-device connections and increase the compatibility.

26.07.2018 Connecting ESP32 to Amazon Web Services - AWS IoT Core

At ThingForward, we are exploring different cloud providers' varied functions for IoT applications. Today we will zoom into Amazon IoT Core. Amazon is leading the cloud market for more than 10 years now, thanks to its enterprise-ready solutions and powerful database services.
