I created a basic Lora network using
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
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
