This is a regular discussion I have with prospect or with different business oriented people about producing electronics in developed countries and costs of devices. When you talk about electronic products in many minds it is equivalent to talk about Chinese production & design. It’s like when you talk about software in a couple of years ago it was a kind of synonym with back-office Indian development.

Sigfox technical basics
Sigfox has just published a documentation on the technical basis of the network. This pdf document is a good summary of all what you need to know to get start on the technology.
The document is attached here Sigfox technical overview
To complete this overview you can also take a look to my different post & video
SNOC SFM10R1 – the easiest way to access Sigfox for makers
Basically SNOC SFM10R1 aka BRKWS01 Sigfox devkit is an easy way to get start on low cost sigfox hardware thanks to the low cost module from wisol based on the low cost chip from On Semi Ax8052. Presented like this it looks like stack on a stack on a stack.
But in my point of view the solution is really more than this. As a maker I know how difficult it is to kickstart a Sigfox project : you have to deal with expensive devkit where you sometime need a Kbis, then you have to deal with sigfox to get an access and at ends if you want to transform you POC in a product you need to change you technologies for cheaper or simper solutions. (here I’m not pointing anyone but basically I had to made my own devkit to start on sigfox) Most of these problems have already been solved thanks to sigfox making account creation so simple for devkit and the arrival of devkit like snootlab, airboard or smart-everything. All these solutions are nice but provides a full stack solution MCU + communication for a price around $100. This is where the SNOC module is proposing an alternative : get an easy access to the sigfox network with a low cost solution you can plug to the MCU of your choice… Arduino, Rpi, Nucleo, Pic it’s up to you !
Smart home and wifi pros & cons
Getting this picture from the social networks it was an opportunity on reacting about the general use of wifi technology for IoT smart home equipment and the risk you have to design a such solution.
The following video is a VLOG about this question. As it is in french, this post will details the main lines about my feeling.
Why is it so long to buy IoT stuff in usual shops ?
Some elements to understand why it is so long to find connected objects in shops like connected car, table, chairs, fork, spoon… even if technologies, networks are available since year 2-3 now ?
This 5min video post is in French.
Life coding – how to use DNA for making robots
A second video : this time about “life coding”. They are technics based on reverse engineering to understand how life and DNA is working to create robots ; even if all of this is more biology than computers I was really touched by the Xavier Duportet talk about these technics and what he is doing.
For these reasons, it is the topic of my second youtube video (as the first on it is in French).
Enjoy !
What left in BlockChain if you avoid talking about crypto and money ?
A new try for this website : my first video post !!
The topic is blockchain and to avoid you to have to support my terrible french accent the talk is in French.
This is a try, so please comment the video to see if it make sense for me to continue that way on this support with such topics.
LoRaWAN is coming !
Last week, Objenious (a bouygues Telecom company) has announced the availability of its LoRaWAN network in France. With already 32 cities covered, about 50% of people can access to the low power network. More over they have announced the deployment of 4000 antennas by end of the year to cover the whole country.
I had the opportunity to test the network and as far as now, I can say it works well, the backend is nice even if it sounds a bit not intuitive yet but for sure they will fix it soon. The good news was a communication about price, with a range of 12€ to 1€ depending on volume, the pricing is really near Sigfox one in a first look. The volume scale will be really important to see the difference as the technical offer (message limit, bandwidth, downlink limit if we have some or not).
In my point of view, Orange is the one loosing most with this announce as they are supposed to start soon with 11 cities in France and they did not yet communicate on the scaling. So now, we are waiting for Orange response and offer in this competition.
The surprising thing in the Objenious announced was the roaming capability with USA as the LoRa frequencies are not compatible between Europe and USA. As most of the device are not yet dual band and the question of detecting the location before emitting still an issue for such use-case, I do not really see how it can have a short term positive impact on project. By-the-way, I was also not aware the LoRaWAN specification for roaming was published. Is it ?
So welcome to Objenious in LPWAN french market, competition is always a good think, and what you announced sounds good and useful for object maker like me.
