This is a quick fork of Thomas Telkamp's single channel gateway, modified to use an Arduino hosting an RFM95 as a radio delegate, dumping packets over the USB-serial to a (linux) PC which runs the rest of the forwarder code.
Some things like RSSI etc end up faked/missing
It has been changes for US 902.3 MHz frequency, and NYC details put in
Currently both the Arduino code and the PC code build out of the same source file with lots of ugly ifdefs (sorry, it seemed like a good idea at the time). That means the Arduino .ino is actually symlink, which works, only if you try to save any edits from the Arduion IDE it will overwrite the symlink with a regular file.
This was a quick and dirty test to get packets pushed into TTN without having to setup a raspberry pi.
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).

- 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)
- 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
