LoRa

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

Dragino LG01 – Hack

  • by

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) between the Dragino mainboard and RFM95. Depending on the application this design works, but when… Read More »Dragino LG01 – Hack

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

LoRa and Sleep

  • by

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 communication, the transmitting and receiving module must be configured with the same frequency, SF, among… Read More »LoRa and Sleep

The Schematic

  • by

How the schematic works?! Basically use two main components, Arduino Pro Mini and RFM95 LoRa Module. The circuit is powered by 2 AA batteries.   RFM95 – LoRa Module The RFM95 is based on the SX1276 chip, a Low Power Long Range Transceiver. It’s uses SPI (Serial Peripheral Interface) and… Read More »The Schematic

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!
