The Things Indoor Gateway (TTIG)

The Things Indoor Gateway (TTIG) has been announced and distributed during the TheThings conference 2019. Since it was impossible to get some, victim of its success (and the little initial stock). From mid-august it is now possible to get some and I’ve bought one as soon as possible.

The Things Indoor Gateway is a low cost (70€ – 90€), 8 channels (EU868 full gateway), LoRaWan gateway running on TheThingsNetwork. You can’t expect a large coverage with a such solution to be used for city wide network but it will be perfect for covering a large house or a small building where you want to deploy LoRaWan sensors.

How to transfer pictures over Sigfox network ?

Yesterday in a communication around Securitas Direct deal a small phrase has waked up all the Sigfox community:

Announcing in a certain way the arrival of 600Bps support for Europe (this is already the North American standard speed) to support the picture transfer over the LPWAn network. That said, even at 600Bps it’s a bit complex to transfer a picture… let’s see what we can do with this:

Getting started with ST Murata LoRaWan board

ST Micro-Electronics is providing a development board with a Murata CMWX1ZZABZ-091 chip. This device is a module containing a STM32L0 chip (192Kb of Flash / 20Kb of RAM) associated with a Semtech SX1276 radio chip. This module can be used as a SoC for developing LoRaWan IoT devices. The Semtech chip is also capable of Sigfox. This module is a bit expensive but it is actually the one allowing LoRaWan and Sigfox communication in any of the RCZ zones.

The Sigfox Micro Base Station test

The Sigfox Micro basestation has been announced during the last Sigfox Connect event in Berlin. The base-station allow to extend the Sigfox public network, at low price, for your private location.

This post is detailing my experience with the micro base-station and the field test I’ve made on an industrial site.

Send Sigfox messages with STM32 + S2LP

STM32 solution for using Sigfox is actually one of the best offer on the market has the solution is powerful, low consumption and allows global coverage with the use of the last Sigfox library versions including Monarq, Bubble… Different module providers are actually designing solutions based on this platform.

In this post we are going to see how to configure the STM32 platform, starting from a STM32L053 devkit plus a S2LP extension. Using a eclipse/gcc environment. The environment installation is described in this post about installing Eclipse for STM32.

Introduction du IoT LPWAN – year 2018 update

For the second year I had the chance to introduce the IoT and LPWAN networks to a group of 150 students in computer engineering school. This year we add a longer time to detail a bit the Sigfox and LoRaWan solution and I’ve added a part on the IoT security.

I’ve tried to propose a different point of view on security aspect, not based on fear but practical things to do and a larger contextual aspect. I’ll try to make video on this specific topic on my Youtube (where you can find in french most of the content of these slides).

So … here are the slides, for my students who joined or not the conferences, and for those who would like to join this course.

SigfoxConnect disclosed – Sigfox micro gateway

This was the more expected announcement for Sigfox Connect  event: the availability of the micro-gateway: a Sigfox gateway you can buy, own and deploy on your own location.

This was expected to be introduce has it has already been disclosed once FCC certification made it public as it has been noticed by Nestor Ayuso on twitter some days ago.

This model is standard for LoRaWan ecosystem running on private network as on public network. For Sigfox it has always been possible to expend the network but it was a little bit complex because you had to rent the basestation from Sigfox and the basestation itself was an operator equipment: something made for being installed on a roof, not in your office.

Sigfox is now proposing the micro-gateway !

LoRaWAN gateway from TheThingsNetwork

TTN Gateway

I’ve waited a long time to get it since I pledge on the kickstarter campaign but it’s now here and as all what TTN have done until now this it a really nice object.

The design itself is really good. You can easily fix it on a window or a wall.

You can hack this gateway a lot … by the way it is not yet my purpose.

And the installation process it so good.. You may understand I really liked it.
