Texas Instrument’s CC3200 is a single-chip microcontroller unit with built-in Wi-Fi connectivity, created for the Internet of Things. It can run the FreeRTOS operating system and provides a hardware encryption engine. Sounds interesting? It did to us! So we created a demo that is capable of streaming two-way audio between the CC3200 and an Android […]

This is an updated version of a previous post incorporating our Cloud Console. When working with STM32 ARM Cortex-M microcontrollers, the free embedded software STM32Cube from ST provides all necessary drivers and a collection of middleware components to reduce the initial development effort. One of the mentioned middleware components is the popular FreeRTOS real-time operating system Nabto is partnering […]

At Nabto we are using many technologies in our platform, one of them is Cassandra. We are monitoring Cassandra with the following setup setup: Cassandra + Prometheus JMX Exporter -> Prometheus -> Grafana. This setup has a component which does not meet our requirements for a production setup: The Prometheus JMX Exporter uses too much […]

The ESP8266 is a low-cost WiFi module that can be programmed directly like a microcontroller. Already thinking of your next Internet of Things project? While an available Arduino library allows a quick start, there is still one problem to overcome: How to access your ESP8266 from outside your home network without nerve-racking router and firewall […]

Today we will have a look at the Arduino-like Jorjin Ameba board with built in support for WiFi and NFC. Taking the pricetag of 25$ into account makes this an easy choice for your IoT projects! For this post I created a Jorjin Ameba library which can be imported directly into the Arduino IDE seamlessly, thus making the […]

Please read Part 1 to read about the preliminary steps in the Roomba saga. This part will be the fun part where we turn the Roomba into a fully fledged remote controlled vehicle fitted with realtime video feed as well! If at any time you feel like trying this yourself, you can sign up for a free […]

As some of you might have seen on twitter we had a device laying around at the Nabto headquarters with Nabto written all over it. [tweet https://twitter.com/nabto_com/status/735109173466267650 align=’center’] Today is the grand reveal of our Roomba hack! Like the CoffeePi this project was rather substantial so the Roomba hack will be split in two parts. […]

The experimental open-source project Dartino enables you to write software for embedded systems using the modern Dart language and a set of libraries, that let you be highly productive. So why not add another powerful library? Thanks to improvements to the FFI library in the latest Dartino SDK, we are now able to use the uNabto framework from […]
