I attended the Sierra Wireless Innovation Summit, on last Wednesday and Thursday. Which means that I got the opportunity to play with a mangOH Yellow board and Octave, and that I brought back home the board 🙂
Before starting to write my first own application, today I connected a lithium-ion battery to the board, and configured Octave to display charge status. Which took me less than one minute. Impressive.

I wanted to configure STM32CubeIDE so that it replaces tab character by spaces, when editing source code. Easy, once one knows where to look:

- select Window > Preferences
- select C/C++ > Code Style > Formatter
- create a new profile, based on the profile you prefer
- in the Indentation tab, select Spaces only for Tab policy
A list of device software environments that provide some IoT-oriented functions:
To be continued…
I had to help someone starting a project which includes, among others, a Pysense board.
The development environment was Linux Mint 18.3, running in a VirtualBox virtual machine (VirtualBox version 5.2.26). The host system was a MacBook Pro running macOS Mojave.
One difficulty that the user may face with this environment relates to the USB device redirection. When the Pysense is switched to bootloader mode, for firmware upgrade, it stays in this mode less than 7 seconds, which is not long enough to configure VirtualBox.

I have to integrate some Go applications into a distributed validation environment that I’m currently developing. These applications use UDP to exchange messages. I’m well experienced in message-based communication, for several different types of transport layers (wireless, wired, half duplex, full duplex…) but never got the opportunity to use the UDP/IP stack until today.

A word of caution: platform can have different meanings in the list below. It can be a software development framework, a software application providing communication (and possibly management and storage) services, a hosted application providing those services, etc. But the common point between all the items in the list is at least some technical mean easing communication between devices in the field (in vehicles, at home, in the pocket, around the wrist, etc.) and some users, usually through some part of the Internet.

In this article, we will see how to add Developer Studio, the Sierra Wireless Eclipse-based IDE, to the VM we built in previous article. By default, Developer Studio is configured for a previous version of Legato (the official production version). To be able to use the latest Legato version that we installed in previous article, some additional configuration must be performed. We will go through associated steps. Continue reading “mangOH Red: configuring Developer Studio”
To develop for the mangOH Red board, you can use an Ubuntu-based virtual machine, provided by the mangOH team. It turns out that I prefer Linux Mint to Ubuntu, mainly because of the window manager, and I wanted to start trying to understand how the mangOH development environment is structured and works. So I decided to set up my own development VM, based on Linux Mint.
In this article, I describe the various steps I followed to create this VM. Continue reading “mangOH Red: using a Linux Mint VM for development”
I just delivered a new version of the talk I give to postgraduate students of a Telecom and Electronics Master of the University of Nice Sophia-Antipolis (France). I added the presentation of a simple end-to-end IoT system demonstrator, using LoRa in device-to-device mode, that I specifically developed for this talk.
The presentation is available on SlideShare, while the demonstrator source code is available on GitHub.
