He de reconocer que ha sido algo doloroso el poder acabar hacer funcionar el IDE de Arduino con estos dos módulos LoRa con ESP32, por eso he querido documentar los pasos y errores que me he encontrado. --> Actualizado!!!, ahora no parece ser tan doloroso

So, I've made a video with some radio modules you could use. In this case we will see the LoRa radio module with SPI serial communication. See the connections below, download the example code and test if it works. You will need the LoRa library as well so download that from the links below. You need two modules, an LED and a potentiometer and we will send just one byte of data, 0 to 255 values. The range for this module could be up to 5Km abut we need a lot of pins to use this.

The IoT industries introduced lots of technologies, but none of them was ideal for IoT devices, as they needed to transmit information to a long distance without using much power until the LoRa technology was introduced. LoRa Technology can perform very-long range transmission with low power consumption. According to Industry analyst IHS Market by 2023, 43% of all LPWAN connections will be based on LoRa. LoRa Technology is flexible for smart cities, smart homes, smart agriculture, smart metering, and smart supply chain & logistics applications.  

Previously we learned about LoRa technology and interfaced SX1278 Lora Module with Arduino. Now we will replace the Arduino, and use ESP32 with the SX1278 LoRa module. Here two LoRa modules will be interfaced with two ESP32 Boards to send and receive data packets from one board to another. ESP32 is a very popular Wi-Fi transceiver and microcontroller, learn more about ESP32 and its working by going through various IoT applications built on it.

This is an example of a nice LoRa project. The weather station contains a temperature sensor, air pressure sensor and humidity sensor. The data is read out and sent to Cayenne Mydevices and Weather Underground using LoRa and The Things Network.

In this tutorial we’ll explore the basic principles of LoRa, and how it can be used with the ESP32 for IoT projects using the Arduino IDE. To get you started, we’ll also show you how to create a simple LoRa Sender and LoRa Receiver with the RFM95 transceiver module.

Learn the fundamentals of low-power wide-area networks, and what Arduino hardware can connect to them.

The box contains an Arduino Mega that interfaces with an RFID reader to enable the current owner to scan in, plus a GPS module for location data. Additionally, an LDR sensor can be incorporated to set the brightness of an LED matrix on the outside.

Data passed along to a Raspberry Pi for time of possession tracking via LoRa with The Things Network. This also runs a server that shows game info to others playing, meaning that you’ll have to be very careful to keep it around!

Code for the project is available on GitHub.

An important new feature is now available in the Arduino IoT Cloud — full support for LoRa® devices!

LoRa® is one of our favorite emerging technologies for IoT because it enables long-range and low power transmission of data without using cellular or WiFi connections. It’s a very powerful and promising technology but it comes with its own complexity. In our pursuit to make IoT easier, we’ve already released a few products that enable anyone to build a LoRa® device (or a fleet of LoRa® devices!). Thanks to the Arduino MKR WAN 1310 board, combined with the Arduino Pro Gateway, you can create your own LoRaWAN™ network. But we have decided to do more than that, and it’s time to release one more important piece…

In this article, we will learn about LoRa technology and Arduino Lora Communication. Here we will interface SX1278 Lora Module with Arduino and establish LoRa communication between two Arduino Uno boards.

Circuit diagrams for LoRa transmitting and receiving side are given below. In this project, we are going to send temperature and humidity values from one Arduino to another using LoRa SX1278 module. The DHT11 sensor is connected to transmitting side, Arduino. So this Arduino will get temperature and humidity values from DHT11 and then send it to another Arduino via LoRa SX1278 module. These humidity and temperature values will be printed on LCD connected to second Arduino.
