Using LoRa with Raspberry Pi - Peer to Peer Communication with Arduino

For the complete tutorial to use LoRa module with Raspberry Pi, visit: What is LoRa and How to Use it with Raspberry Pi: The term LoRa stands for Long Range. It is a wireless Radio frequency technology introduced by a company called Semtech. This LoRa technology can be used to transmit bi-directional information to long distance without consuming much power. LoRa is getting increasingly popular with the advent of IoT, Connected Cars, M2M, Industry 4.0 etc. Because of its ability to communicate to long distances with very less power it is preferably used by designers to send/receive data from a battery powered Thing. We have already discussed the basics of LoRa and how to use LoRa with Arduino. Although the technology is originally intended for a LoRa Node to communicate with a LoRa gateway, there are many scenarios in which a LoRa Node has to communicate with another LoRa Node to exchange informa
