# Multi Mode LoRa Gateway-Repeater
## Arduino ESP32 based LoRa to Wifi MQTT Gateway

INNOVATE AUCKLAND
Copyright (c) 2019 Innovate Auckland. All rights reserved.
Included libraries are copyright to their respective owners
 
## Functions and features.
This gateway is designed to create a data telemetry connection for environmental IOT projects where standard 2.4 Ghz WiFi and mains power is available nearby.

<li>Receives open LoRa massages and publishes as comma delimited text to MQTT over a standard Wifi connection
<li>Includes an embedded webserver and application for simple setup using mobile or PC
<li>Three main modes of operation, normal gateway mode, repeater mode to extend range and monitor mode for network testing and setup. 
<li>Includes built in reset watchdog
<li>Detects and automatically reconnects on connection failure 
<li>Regularly sends the gateway status including name, type, version, uptime, battery level over MQTT using the keyword GWSTATUS.
<li>Supports onsite network testing/setup with automatic gateway status replies over LoRa and MQTT triggered by a gateway message sent in monitor mode. Note this function requires a multimode gateway in monitor mode.
 
 
NOTE: If your project location does not have access to mains power or a suitable Wifi connection nearby, please <a href="mailto:aklciot@gmail.com">contact us</a> about how to get our mobile solar powered gateway.

## Contents:
This page describes the Innovate Auckland Telemetry Gateway. On this page you will find details on where to buy supported hardware, details on the gateway operation, source code and the <a href="https://github.com/aklciot/TTGO-Gateway-repeater/blob/master/USER_GUIDE_MulitimodeGateway_1.0.pdf">operating manual for setup and advanced features</a>.

The gateway sends data from the sensor to the internet. To make this work the gateway needs to know your WIFI name and password to make a connection. The gateway uses very little data, about 20MB per month, as much as listening to a few music tracks. It also contains no personal data and has no microphone or camera. The gateway does not accept any inbound connections making it very resistant to hacking, all internet connections are outbound only. Power utilisation is about 150mA, less than 1 watt (1/10th of a standard LED light bulb).

## Important:  This opensource software is free for non-commercial use only.
Please review and respect the licences for included libraires.
For any commercial applications, please contact us.

## Compiling and loading
This code can be compiled on a standard Arduino GUI. Your IDE will need the ESP32 boards added.  See the Arduino support pages for details on how to complete this step.

UPDATE: <a href="https://github.com/aklciot/TTGO-Gateway-repeater/blob/master/NodeExampleUltraSonicSensor.ino">Sample code for a simple LoRa node</a> that works with this gateway is now included to get you started with sensors and IOT devices.

### Libraries
The following libraries are required:
- AsyncTCP (can be installed fromzip file in library folder)
- ESPAsyncWebServer (can be installed from zip file in library folder)
- EEPROM (can be installed from zip file in library folder) (N.B. This library has been depreciated and should be replaced by Preferences. Raised as [issue #2](https://github.com/aklciot/TTGO-Gateway-repeater/issues/2))
- Adafruit MQTT
- ESP8266 and ESP32 OLED driver for SSD1306 displays
- RH_RF95.h from RadioHead

## Setup for different gateways
* The node ID, repeater ID etc needs to be set up in `param.h`
This should be configurable by the web interface over WiFi, [Issue #1](https://github.com/aklciot/TTGO-Gateway-repeater/issues/1) raised for this feature
* MQTT setting need to be done in the `param.h1` file
This should also be configurable over the web interface - see [Issue #3](https://github.com/aklciot/TTGO-Gateway-repeater/issues/3)

## Getting the Gateway Hardware
The gateway software runs on three variants of TTGO LoRa Wifi ESP32 device that is compatible with Arduino ESP32.
 NOTE: Ensure you select the correct frequency, (915Mhz version for New Zealand use) or region.
Edit the gateway code to match the hardware gateway device you have.

## Gateway Modes of operation:

There are four operation modes.

### Setup Mode:
 This mode allows the end user to enter the WiFi connection credentials and select the mode of operation.

### Gateway Mode:
 This is the main operation mode.  Gateway mode receives sensor data over LoRa and sends it over the internet to the data processing service.

### Repeater Mode:
This mode converts the gateway in to a LoRa to LoRa signal repeater that extends the range of the network and allows sensors to be put in locations where the gateway cannot otherwise make a connection.

### Monitor Mode:
The signal monitor mode primary function is during network setup. The monitor provides unique features to assist in location decisions including signal strength and auto reply functions. This mode also provides local only (iwi) mode, this is an important feature identified by Mana Whenua ensures data remains in the local area.
