Mannie Peterson (aka FellFromTree) developed an embedded operating system called HeliOS, which is specifically designed for 8-bit and 32-bit Arduino boards and is easy to use with the Arduino IDE. HeliOS is said to only have 21 function calls and implements collaboration, event driven multitasking, task notification / messaging, timers, and memory management.

How does HeliOS work?

HeliOS was written with hobbyists, enthusiasts and researchers in mind who want more functionality than what existing task schedulers offer yet want to avoid the size and complexity of an RTOS. HeliOS has only 21 function calls and implements a wide variety of functionality including cooperative multitasking (run-time balanced), event driven multitasking, task notification/messaging, timers and managed memory. Not only is HeliOS easy to use, it is conveniently available through the Arduino IDE Library Manager or from GitHub as a ZIP file and has out-of-the-box support for Arduino AVR, SAM, SAMD and ESP8266. Either way, HeliOS is compliant with Arduino’s 1.5 (rev 2.2) Library Manager Specifications so getting started is a snap!

ESP32-based LoRa / LoRaWAN wireless network

One way of long-range and low-power data transmission is LoRa wireless technology. Since the Internet of Things market (with ESP32 – based solutions) is mainly covered with short-range Wi-Fi and Bluetooth and long-range with 3G / NarrowBand-IoT technologies, LoRa oftens is omitted or simply unknown by IoT users. Below you will find a short representation of what LoRa is and how can it be used.

What is LoRa / LoRAWAN network?

LoRaWAN® network architecture is deployed in a star-of-stars topology in which gateways relay messages between end-devices and a central network server. The gateways are connected to the network server via standard IP connections and act as a transparent bridge, simply converting RF packets to IP packets and vice versa. The wireless communication takes advantage of the Long Range characteristics of the LoRa physical layer, allowing a single-hop link between the end-device and one or many gateways. All modes are capable of bi-directional communication, and there is support for multicast addressing groups to make efficient use of spectrum during tasks such as Firmware Over-The-Air (FOTA) upgrades or other mass distribution messages.

NarrowBand-IoT the new black of Industrial IoT

The NB-IoT is becoming a standard in wireless communication of IoT devices, for standalone solutions and complex installations with thousands of units, coordinated with gateways. Will NarrowBand-IoT replace other wireless technologies in industrial automation?

What exactly is NarrowBand?

NarrowBand-IoT (NB-IoT) is a radio technology in the field of LPWAN (Low Power Wide Area Network) dedicated for IoT devices, operating on the licensed frequency band used by telecommunications operators.

The biggest advantages of NB-IoT include:

  • long battery life (up to 10 years),
  • efficiency in the amount of data transferred,
  • intra-building penetration,
  • the ability to connect even tens of thousands of devices in one system,
  • a global standard,
  • a high level of security and low cost

You can build mass solutions and those that until now were considered unprofitable. NB-IoT technology works in the licensed band, so there is no risk of interference and blocking communication by competing networks.

The service life of devices powered by two AA batteries is up to 10 years. However, the devices themselves are constructed in such a way that they can work for many years without the need for technical supervision and recharging the battery.

NB-IoT used in industrial solutions

Sigfox announces changes improving IoT applications

First major announcement is that Sigfox will launch a private network (PAN) that will allow IoT customers to choose private and global services according to their needs. The service was launched for the first time in France in the first quarter of 2020, but Sigfox will be implemented in over 65 countries.

The operator’s wide area network (WAN) will be completed next year in cooperation with Eutelsat. Sigfox provides coverage worldwide using the nano-satellite constellation launched by Eutelsat.

The Sigfox PAN offer will benefit from the existing Sigfox WAN ecosystem. Thanks to the potential to use all components on the market and the use of very low transmit power to support facilities without the need for batteries, the Sigfox PAN offer offers enormous potential,

Ludovic Le Moan, CEO and co-founder of Sigfox.

According to Sigfox, by the end of 2019, there will be more than 15 million registered facilities and over 1,500 customers using this solution in various industries around the world. Sigfox says that PAN customers can expect the same as WAN customers in terms of support and quality. PAN clients can choose to subscribe to additional „WAN Extension” services if needed if the device needs to communicate outside the local network.

Sigfox improving the accuracy of Atlas geolocation services

Internet of Things operators have now launched Atlas Native Complimentary. It is made available free of charge in exchange for the rights to process data regarding GPS data. These data are compared to the fingerprint of the Sigfox network using machine learning, which increases accuracy to 800 meters.

To further increase the accuracy of its geolocation services, Sigfox said it has completed the global implementation of Atlas WiFi in collaboration with HERE Technologies’ mapping experts.

Sigfox uses the global WiFi access point database here. Access points are checked by the Sigfox WiFi tracking module and more closely track the location of external and internal resources with less battery consumption than using GPS.

We are delighted to strengthen our partnership with Amadeus and share our combined expertise to create real digital transformation of the travel sector. Our strategic alliance named PinPoint will not only help to improve the travel experience, but this will also change completely the game for an industry looking for decades for THE technology able to save costs while improving efficiency and quality of services

ESP-MESH is a network protocol based on the Wi-Fi protocol. ESP-MESH enables the connection of a large number of devices (hereinafter nodes) covering a large physical area (both inside and outside) over a single WLAN (wireless local area network). ESP-MESH self-organizes and self-heals, allowing you to build and maintain networks autonomously.

Traditional Wi-Fi Network Architecture. Source: espressif.com

Traditional Infrastructure of Wi-Fi network is a point-to-multipoint network in which a single central node called an Access Point (AP) is directly connected to all other nodes called stations. The AP is responsible for arbitrating and forwarding transmissions between stations. Some access points relay transmissions to and from external IP networks through routers.

Traditional Infrastructure Wi-Fi networks have the downside of having a limited coverage area as all stations need to be in range to connect directly to the access point. In addition, the maximum number of stations allowed in the network is limited by the bandwidth of the access point, making traditional Wi-Fi networks prone to overload.

ESP-MESH vs traditional Wi-Fi infrastucture

ESP-MESH differs from traditional Wi-Fi infrastructure networks in that the nodes do not have to connect to a central node. Instead, the node can connect with its neighbors. Nodes are responsible for relaying transmissions to each other. This allows for achieving interconnections without the need for nodes to be within the range of the central node, which significantly extends the coverage area of the ESP-MESH network. Likewise, ESP-MESH is less prone to congestion as the number of allowed nodes in the network is no longer limited by a single central node.
