Lora SX1272 test code

LoRa SX1272 test code

This repo contains test code for LoRa SX1272 radios connected to Raspberry Pis.

Hardware Requirements

• 2 x Raspberry Pi 2 Model B
• 2 x Raspberry Pi to Arduino shields connection bridge
• 2 x LoRa Module SX1272 (868/900MHz)

Compile software

Clone repo both Raspberry Pis

git clone https://github.com/mngiess/lora-sx1272-test.git

Compile arduiPi library for Raspberry Pi 2.0

cd raspberrypi_2.0
./compile_rpi2
cd ..

Compile SX1272 driver

g++ -I./raspberrypi_2.0/ardupi2.0 -c SX1272.cpp -o SX1272.o

Compile transmitter application

g++ -I./raspberrypi_2.0/ardupi2.0 -lpthread -lrt transmitter.cpp SX1272.o ./raspberrypi_2.0/ardupi2.0/arduPi.o -o transmitter

Compile receiver application

g++ -I./raspberrypi_2.0/ardupi2.0 -lpthread -lrt receiver.cpp SX1272.o ./raspberrypi_2.0/ardupi2.0/arduPi.o -o receiver

Running it

First Raspberry Pi run the receiver

./receiver

Second Raspberry Pi the the transmitter

./transmitter
