My Node Died (LoRaWAN)

In April 2019 I installed a node here at home! The goal was to see how long a battery-powered Arduino stays online measuring the temperature and sending this data through LoRaWAN. After 89357 data sent to The Things Network (TTN) the Node stopped sending since the battery ran out, which… Read More »My Node Died (LoRaWAN)

LoRaWanPacket

  • by

I have this library for some time, I created to make possible to encode and decode packages of LoRaWAN on Arduino. The idea is to insert de keys and configuration of the device on the library and then the crypto and the mic check is automatically generated from the LoRaWanPacket.… Read More »LoRaWanPacket

SimpleLMIC

  • by

LMIC means LoRaWAN-MAC-in-C and the most popular is the arduino-lmic library, the problem is the library is a little low level and for noobs is a little confusing to work with. One solution is to use the arduino-lorawan library that uses the main arduino-lmic and provides a higher level, more… Read More »SimpleLMIC

LoRaNow Library

  • by

I’m playing with LoRa and LoRaWan for some time and is an incredible technology, but when you want to create something nice is a little hard, especially with LoRaWan. LoRaWan library is a little crazy and is not user-friendly, but has a lot of nice features, like frequency swap, encryption,… Read More »LoRaNow Library

Unique ID

  • by

Hello, I have played with Arduino (Atmega328p) for a long time. In an old project, I needed to differentiate two Arduino Uno, so I try to find some kind of a Serial Number on the datasheet form the Atmega328p. The datasheet doesn’t have anything about Serial Number, and I implemented… Read More »Unique ID

CayenneLPP

  • by

Hello, This week I was messing with some payload formats and I came to the conclusion the easiest and smartest way make a package is by using CayenneLPP. Cayenne Low Power Payload (LPP) is a library designed to make packages for LPWAN networks such as LoRa and LoRaWAN. This video… Read More »CayenneLPP

My first board!

  • by

I started playing with LoRa when I bought some RFM95 module, it was really boring and messy playing with wirings… So I decided to make a board, the idea was to make a pcb to put RFM95 and Arduino Pro Mini, power the whole board with 2 AA battery. And… Read More »My first board!
