Arduino PRO Gateway for LoRa now available for pre-order

We are very happy to announce the Arduino PRO Gateway for LoRa!

Combined with Arduino MKR WAN 1300 IoT nodes it makes an ideal solution for a wide range of applications, like smart agriculture, smart cities and building automation – and many other remote monitoring applications requiring long range, low power wireless connectivity.

The gateway can be used globally and enables multiple channel management. By supporting advanced features like Listen Before Talk (LBT), it allows users to transmit at higher power on the first free channel, achieving longer ranges than conventional gateways for LoRa. 

Arduino continues its mission of making complex technology easy enough for anyone to use. Customers of the Arduino PRO Gateway will be given exclusive beta access to the Arduino IoT Cloud, which makes installation, provisioning and remote management of the gateway incredibly simple through the popular Arduino Create cloud platform.

The gateway features the advanced Embit EMB-LR1301-mPCIe module, hosted by a Raspberry Pi 3 B+ SBC, in a rugged aluminum enclosure. The gateway comes pre-installed with an optimized packet forwarder and a carrier grade Network server for LoRa WAN that is running on the Arduino Cloud provided by A2A Smart City (part of the A2A Group).

Technical Specifications

  • Chipset: Semtech SX1301
  • Modulation: LoRa Spread Spectrum, FSK, GFSK 868MHz (EU) / 915MHz (US)
  • Number of Channels: 8 LoRa Channels
  • Operating Frequency: 868MHz (EU) / 915MHz (US)
  • Frequency Range: 860MHz to 1020MHz
  • Operating Temperature: -40°C to +85°C
  • RF Output Power: Up to +27dBm
  • Sensitivity: Up to -137dBm
  • Interfaces for the LoRa Module:  mPCIe (SPI / I2C / UART / GPIOs) :
  • Dimensions: 71x40x1mm
  • Operating Voltage: +5V
  • Additional Features:
    • Listen Before Talk (LBT) Capability (for improved transmission power management),
    • On-board uFL antenna connector
    • FPGA support for LoRa Spectral Scan

 

The Arduino Pro Gateway for LoRa (868 MHz , EU version) can be pre-ordered from the Arduino Store.

Ardupower

It’s a power stip driven remotely through an Ethernet network using telnet protocol.
The password and tcp parameters are saved in eeprom.
The user can give names to the six power out, that are also stored in eeprom.

Programming Arduino on the cloud: codebender

codebender is web-based IDE, mainly built with HTML5 and Javascript, that focuses on the development for the Arduino platform. Since it is going to be used directly from the browser (note that currently codebender is still beta), it will further simplify the whole development process, avoiding the installation of software and libraries on the local machine.

From the home page of the project:

We want to lower the barrier to entry, which is necessary to help everyday people start their first project, become makers and advance technology instead of using it. codebender requires no installation, so you can get started with Arduino programming the minute you get one in your hands! And with the development tools we provide, you can do so faster and easier! codebender also stores your code on the cloud, so it’s safe and accessible from anywhere, anytime.

Several nice features will be available soon, such as remote flashing: together with an Ethernet shield flashed with a properly designed TFTP bootloader, you will be able to upload a sketch remotely, over the internet! Another nice feature regards its integration with the open documentation available on the Arduino website, which will be accessible directly from the IDE by selecting a piece of code and, then, by pressing ctrl+space.

More information can be found here.

WISP: a WiFi module for the Internet-of-Things

embdSocial™ is an Internet-of-Things (IoT) platform usable to provide communication support to smart objects and devices. embdSocial™ is based on WISP™, an electronic module that can be connected to any microcontroller-equipped device (such as an Arduino board, by means of ad-hoc shield) to exploit several communication services:

Each WISP™ allows real-time bi-directional communication through our secure, globally accessible API. In addition to merely providing internet connectivity, embdSocial™ provides one interface and architecture that simplifies common tasks through the use of plug-ins:

  • Tweeting/receiving @messages
  • Updating Facebook statuses
  • Sending/receiving emails
  • Sending/receiving SMS text messages
  • Manipulating files in your Dropbox

Each WISP™ is equipped with a 802.11 network interface (with support to WEP, WPA and WPA2 protocols) which allows the device to be easily connected with the embdSocial™’s servers; moreover, its configuration is completely web-based.

More information can be found on the embdSocial™ homepage, together with a couple of videos presenting its capabilities.

Publishing data on the web with Node.JS

Many solutions exist for publishing data coming from Arduino boards on the web. Bangon Kali, in his detailed tutorial, proposes his novel approach, which makes use of several widespread and open-source technologies, such as Node.JS, jQuery and Apache:

Using the USB, the Arduino Board is connected to the PC serially to a certain COM port which the OS allocates. Node.JS, the asynchronous server side JavaScript engine then listens for the port using a Node.JS module called SerialPort2. When a signal is received, using the Node.JS Socket.IO module, data is then served also asynchronously to the web providing a real time feed of the Arduino signal.

The tutorial (which can be applied on Linux, Mac OS and Windows) can be found here.

Hacker builds allegedly pointless data network out of Lego train set

How can we appreciate bullet-quick SSDs and fiber networks without pausing -- at the year's end -- to appreciate where it all came from? We should think back to before the birth of modern computing, even before the telegraph, to a time when bits of data were forced to travel everywhere by train. A hacker named Maximilien has now recreated that locomotive golden era using Lego, Arduino and Linux, and what his system lacks in bandwidth it more than makes up for in historical relevance. A USB flash key is borne by miniature railway carriage from station to station, stopping at each one to unload or pickup information and thus creating its own barebones networking protocol. Click the source link to appreciate the full museum piece.
