Commençant à utiliser de plus en plus de produits basés sur des ESP8266, je vais vous décrire ici la manière générique de réaliser des mise à jour sans fil dite OTA pour les produits sur lequels j’écris le micrologiciel. Attention,… Continue Reading
I think there’s too much time I did not talked about ULPNode project, good news, it’s now time to talk about it and it’s timeline. And it’s difficult to find a good starting point since all that I will describe… Continue Reading
ULPNode RF Protocol ULPNode RF Radio protocol was intended first time to be part of ULPNode library, but as soon as I tried to compile gateway code for other target as ESP8266/Particle/PI and others, some targets env compile all source… Continue Reading
Pourquoi ? Travaillant sur différents projets utilisant la téléinformation dans des environnements assez variés (Arduino, Raspberry, Spark Core, ESP8266, …) j’en avais un peu marre de devoir faire des copier/coller de mon code original écrit il y a quelques années… Continue Reading
Currently working with Ultra Low Power nodes project (formerly ULPNode), I was searching for a small but powerfull gateway. What job for this gateway ? My goal is to be able to do a lot of thing with the gateway, even having… Continue Reading
Today I would like to introduce a new breakout board to read temperature values from the most used sensors in the industry such as PT100 and PT1000 (well at least in France). Why this board ? It’s not the first… Continue Reading
After several articles and some intensive tests with ULPNode, it’s now time to explain how the low power engine has been built. Even if you can find plenty of Arduino clone node, when it’s time to power them with battery… Continue Reading
Today I wanted to do a quick project status of the 1st prototype of ULPNode I received some days ago. After the introduction of ULPNode, and both articles about bootloader (1 and 2) used, for this one I will start with… Continue Reading
