Single Channel LoRaWAN Gateway

This repository contains a proof-of-concept implementation of a single channel LoRaWAN gateway.

It has been tested on the Raspberry Pi platform, using a Semtech SX1272 transceiver (HopeRF RFM92W), and SX1276 (HopeRF RFM95W).

The code is for testing and development purposes only, and is not meant for production usage.

Part of the source has been copied from the Semtech Packet Forwarder (with permission).

Maintainer: Thomas Telkamp thomas@telkamp.eu

Features

listen on configurable frequency and spreading factor
SF7 to SF12
status updates
can forward to two servers

Not (yet) supported:

PACKET_PUSH_ACK processing
SF7BW250 modulation
FSK modulation
downstream messages (tx)

Dependencies

SPI needs to be enabled on the Raspberry Pi (use raspi-config)
WiringPi: a GPIO access library written in C for the BCM2835 used in the Raspberry Pi. sudo apt-get install wiringpi see http://wiringpi.com
Run packet forwarder as root

Connections

SX1272 - Raspberry

3.3V - 3.3V (header pin #1) GND - GND (pin #6) MISO - MISO (pin #21) MOSI - MOSI (pin #19) SCK - CLK (pin #23) NSS - GPIO6 (pin #22) DIO0 - GPIO7 (pin #7) RST - GPIO0 (pin #11)

Configuration

Defaults:
