Lora-Network

I created a basic Lora network using

• Arduino as a micro controller

• Lora Dragino shield link

• Raspberry pi

• Raspberry pi Lora hat link

• As a back-end server i used Node-Red

• To control the system , i used an iOS application as interface

Architecture of the network

The arduino communicate with each others using Lora technology , the data is saved using SQLite on the pi the communication between the ios application and pi is done using API request via Node red

the code of the arduinos is found at https://github.com/dragino/Lora the code of the piHat is found at https://codeload.github.com/dragino/rpi-lora-tranceiver/zip/master

Setup Raspberry pi Hat

after Downloading the pihat code change directory to rpi-lora-tranceiver/ dragino-lora-app-w1 then enter the following commands

if no text was entered , the pi is in receiving mode

Make sure that the pi and the arduinos have the same frequency and SF
