If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again.

If nothing happens, download the GitHub extension for Visual Studio and try again. Version : 0. Originally designed by Maarten Westenberg mw hotmail. The software implements a standard LoRa gateway with the following exceptions on changes:. The minimum amount of frequencies supported by a full gateway is 3, most support 9 or more frequencies.

This software started as a proof-of-concept to prove that a single low-cost RRFM95 chip which was present in almost every LoRa node in Europe could be used as a cheap alternative to the far more expensive full gateways that were making use of the SX chip. As the software of this gateway will often be used during the development phase of a project or in demo situations, the software is flexible and can be easily configured according to environment or customer requirements.

There are two ways of interacting with the software: 1. Modifying the config.

WiFi LoRa 32 (V2)

It is recommended to compile and start the single channel gateway with as little modificatons as possible. This section describes the minimum of configuration necessary to get a working gateway which than can be configured further using the webpage.

Now your gateway should be running. Use the webpage to set "debug" to 1 and you should be able to see packets coming in on the Serial monitor. There are some parameters that are hard-coded in the source code. In other words, these settings cannot be changed from the web interface:. The config. All have their definitions set through define statements. In general, setting a define to 1 will enable the function and setting it to 0 will disable it. Also, some settings can be initialized by setting their value with a define but can be changed at runtime in the web interface.

For some settings, disabling the function with a define will remove the function from the webserver as well. However the memory available for heap and variables is limited to about 80K bytes For the ESP this is higher. The user is advised to turn off functions not used in order to save on memory usage. If the heap drops below 18 KBytes some functions may not behave as expected in extreme case the program may crash.This means the device is best tuned at this frequency.

The exactly work frequency is set in the software. In this case, User can choose the Mhz version, the performance is similar. Yes, in our product, the Mhz and Mhz module use the SX HF Radio path, the difference of these two modules are 3 inductors which can let the module work best in MHz or Mhz. So if user use the Mhz model as Mhz, the software is complete the same. So use Mhz in module won't work, actually it might work if you put both transmit and receive device very very close.

FirstUser should notice: Radio link quality and performances are highly dependent of environment.

Better performances can be reached with:. Check if the modem is set to the correct modulation, Different modem setting will affect heavily in the distance and datarate. Examples calls is as below:.

In case User use the RadioHead Library, user can download a modified version from Dragino Modified Radiohead Lib which add extra function to support change the Bandwidth in sketch. Both devices can communicate with each via LoRa. There are some things need to be considered:. The update interval for each LoRa node is also quite important.

Get gateway the step-by-step tutorial and the leaflet describing how to build the low-cost LoRa gateway. Have a look at the antenna tutorial as well to see how to optimally deploy your gateway. The gateway can receive from any LoRa device and is designed to be fully customizable for a targeted application with post-processing features based on high-level languages such as Python.

There are many advanced and well-integrated LoRa gateways capable of simultaneous reception on several channels and implementing the LoRaWAN specification. These gateways are based on the SX baseband concentrator.

This solution keeps the cost of the gateway low and can satisfy small to medium size deployment scenario for ad-hoc application cases in various private usages, farming, agriculture, infrastructure surveillance, application-specific telemetry systems, Note that more than 1 gateway can be deployed to serve several channel settings.

However, it is probably not adapted, in the current state of development, to large-scale deployment with a large number of end customers from various different organizations with their own and different requirements regarding data management, confidentiality and security. Go to our GitHub repository which keeps the latest version the low-cost gateway software. There are a lot of information on the GitHub pages and these pages will be the ones with the most up-to-date information.

How to use Lora with an arduino, and how to send sensor data

Here, we will more focus in describing the underlaying software architecture and details of the low-cost gateway. The gateway is based on a Raspberry PI. But there are also low-cost breakout PCB alone such as those proposed by Charles Hallard on his github. This version can also be used for the gateway although it is more designed for an end-device. There is also this nice breakout from ccadic 's github and this one from Tindie. We enhanced the gateway code but maintained compatibility with Arduino therefore the main features are available on both platforms which can be very convenient when deploying Arduino-based very light-weight gateways.

The original SX library has been significantly improved to support also the SX, to add CSMA-like capability to increase LoRa efficiency and implement the possibility to dynamically ask for an ACK from the receiver side as well as handle downlink messages. Note that the original Libelium library drives the LoRa module does not use DIO pins as many other libraries do, so there is no need to connect these pins. Of course, you have to check first. Some may also use the RST pin to reset the module.

The original library adds 5 bytes for internal usage as shown is the following figure, taken from the Libelium documentation. The dst addr allows the library to filter packet at the receiver by comparing with the end-device addr that should be set at startup. Therefore, the current maximum number of nodes is 1 is usually used for the gateway and 0 is usually used to indicate broadcast. A packet type field has been added to ease the decoding process. The Libelium SX library defines 10 so-called LoRa mode that use various combinations of LoRa parameters: bandwidth, spreading factor, coding rate.

Figure below shows these combinations and the time on air associated to them. The payload value includes the 5-bytes header. Figure: Defined Libelium LoRa mode and their time on air. The philosophy of our proposed gateway is to keep the low-level radio gateway code very simple while having advanced post-processing features implemented by end-user with high-level languages such as Python.

Basically, the low-level gateway redirects on UNIX stdout everything that it receives from the end-devices. When receving a packet, the source address, the sequence number, the payload length, the SNR and the RSSI are also provided to the higher level.

The default gateway configuration is to use Libelium LoRa mode 4 The preamble length is 8 and the address is 1. Our approach is to transfer information between the low-level gateway program basically running in a transparent manner and the post-processing operations implemented by end-users in a high-level language.

Note how the gateway is launched now:.

The first task for post-processing is for instance getting and exploiting information on the last received packet. Our provided post-processing program looks for special, well-defined prefix sequences. You can add your own. We also tested with other cloud platforms such as SensorCloud and GroveStreams.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Or on an Arduino board as it will be explained in Section connect a radio module to your end-device and illustrated below. On the breakout Arduino header, you can connect RFM95's DIO0 to a digital pin of your Arduino if you want to use another communication library that needs this pin.

Our communication library does not need it but we left this possibility open. However its main advantage is to avoid the need of an external FTDI breakout cable to program it. If you need to use them, use these 2 pins from the Arduino board.

Our communication library does not need it but we left this possibility open for LMIC stack for instance. As you can see on the picture, you can directly solder the Arduino board on the PCB, or, as we did, use intermediate headers so that the Arduino board can be easily plugged and removed.

You can download all the Gerber zipped archive and view them on an online Gerber viewer. You can easily make them produced on many online PCB manufacturers. Usually, you just need to provide the zip archive and both size and number of layers are detected. You can dramatically decrease the price by using "panelize" option. It is advised to also connect reset pin. It contains all the gateway control and post-processing software. However, the simplest and recommended way to install a new gateway is to use our zipped SD card image based on the Buster Raspbian OS and perform a new install of the gateway from this image.

In this way you don't need to install the various additional packages that are required as explained in an additional README describing all manual installation steps if you want to install from scratch.

Download our zipped SD card image. The current image has everything you need including:. Use an SD card of a minimum of 8GB. Take also a class 10 it is more than recommended! If you have bigger SD card, e. You can use df -h to verify that you have more space after reboot. You can look at various tutorials on how to burn an image to an SD card. There is one here from raspberrypi. We use a Mac to do so and this is our preferred solution.

The Linux version is not very different. The Balena Etcher tool is also very nice and you don't even need to unzip the SD card image. We also use that solution extensively. Important notice : the LoRa gateway program starts automatically when the Raspberry is powered on.

You can try your gateway right away now by building your end-device and jump directly to this section. If you want to connect ssh to the gateway and perform update procedure, read the rest of the section. With the default gateway configuration, the gateway acts as a WiFi access point.
