Hello friends, I hope you are doing well. In today's tutorial, I am going to share our RFM95W LoRa Proteus Library . With this library, we can place two RFM95W LoRa modules in one Proteus design, connect each module to an Arduino Uno and send messages from one board to the other at 868 MHz. The receiver prints every message with its signal strength and its signal-to-noise ratio, and a row of distance buttons lets us test a link of up to 20 km. We will start with the basics of LoRa and the module, install the library files and wire the circuit. After that, we will run the supplied two-Arduino simulation and study the control panel in detail. We will see how the spreading factor, the bandwidth and the output power change the range of the link. We will also understand both Arduino sketches an ...
