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[…]
LoRaWanPacket
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[…]
SimpleLMIC
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[…]
Dragino LG01 – Upgrade
The last time I was able to fix the problem of the single-channel Dragino LG01 gateway, for some reason has the atmega328p between the mainboard and the LoRa module. I believe the Dragino guys did[…]
Radioenge – Hack
Hello, last month I bought a Brazilian LoRaWAN module. Radioenge is a module with stm32l071cz mcu and sx1272 for LoRa communication. This module uses AT communication to configure and send data over the LoRaWAN, and[…]
LoRaNow Library
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[…]
Dragino LG01 – Hack
Dragino LG01 is a single gateway that should work but does not work 100%, due to poor hardware choices. The chip used for LoRa communication is RFM95, which is fine but has an MCU (atmega328p)[…]
Unique ID
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[…]
CayenneLPP
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[…]
LoRa and Sleep
First of all, we need to understand the basic about of the LoRa communication. The RFM95 module is a transceiver, it transmits as much as it receives packets, and because it is a radio frequency[…]
