Single Channel LoRaWAN Gateway

This repository contains a proof-of-concept implementation of a single channel LoRaWAN gateway. It has been tested on the Wemos D1 Mini, using a Semtech SX1276 transceiver (HopeRF RFM95W).

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

Engine is based on code base of Single Channel gateway for RaspberryPI which is developed by Thomas Telkamp. Code was ported and extended to run on ESP 8266 mcu and provide RTC, Webserver and DNS services.

Features

listen on configurable frequency and spreading factor
SF7 to SF12
status updates
can forward to two servers
DNS support for server lookup
NTP Support for time sync with internet time servers
Webserver support (default port 8080)
OTA Updates
Access Point Mode (for OTA)

Not (yet) supported:

PACKET_PUSH_ACK processing
SF7BW250 modulation
FSK modulation
downstream messages (tx)

Added features if you're using WeMos-Lora Shield as gateway

2 On board RGB LED for visual
1 SSD1306 I2C OLED connector
1 On board push button

Assembled WeMos-Lora Shield

Dependencies

gBase64 library by Adam Rudd is now integrated in the project, no need to install
Time library Arduino documentation
NeoPixelBus library is you're using WeMos Lora Shield as gateway

Connections

See things4u in the hardware section for building and connection instructions See WeMos-Lora github if you're using WeMos Lora Shield as gateway

Configuration

Defaults:

LoRa: SF7 at 868.1 Mhz
Server: 54.229.214.112, port 1700 (The Things Network: croft.thethings.girovito.nl) or directly croft.thethings.girovito.nl

Edit .h file (ESP-sc-gway.h) to change configuration (look for: "Configure these values!").
