RPi-Based IoT gateway Offers Cellular, Zigbee, Z-Wave or LoRa

By Eric Brown

Newark Element14 and Avnet have announced a Raspberry Pi based “SmartEdge Industrial IoT Gateway” with 2x Ethernet, Wi-Fi/BT, CAN, serial and optional Zigbee, Z-Wave or LoRa.

Avnet, which last year launched the Zynq UltraScale+ based ‘Ultra96 96Boards CE SBC, announced plans for the Avnet SmartEdge Industrial IoT Gateway at the CES show in early January. At Embedded World last month, Premier Farnell revealed more details on the Raspberry Pi based IoT gateway, which will launch this summer at Newark Element14 in North America and Farnell Element14 in Europe.

The Avnet SmartEdge Industrial IoT Gateway will support Avnet’s IoT Connectplatform to enable cloud connectivity to Microsoft Azure. The Linux-driven embedded PC will support industrial automation applications such as remote monitoring, predictive maintenance, process control, and automation.

Premier Farnell did not say which Raspberry Pi is under the hood, but based on the WiFi support, it would appear to be the RPi 3 Model B rather than the B+. The limited specs announced for the gateway include 8GB eMMC, an HDMI port, and TPM 2.0 security. The image suggests there are also at least 2x USB ports and a coincell battery holder for a real-time clock.

For communications, you get dual 10/100 Ethernet ports as well as 2.4GHz WiFi and BLE 4.2 with an integrated antenna and external mount. The gateway also provides a mini-PCIe interface for optional cellular modems. In addition, the enclosure “features space for an additional internal accessory to provide Zigbee, Z-Wave, or LoRa capabilities, for example, or for multiple accessories through case expansion,” say Premier Farnell.

The system is further equipped with CAN-BUS and RS-232/485 interfaces with Modbus and DeviceNet support, as well as isolated digital I/O. There’s also a 40-pin expansion header for Raspberry Pi HATs and other add-on boards. The system has a wide-range 12-24V DC input plus DIN rail and wall mounting.

Further information

The Avnet SmartEdge Industrial IoT Gateway will launch this summer at Newark Element14 in North America and Farnell Element14 in Europe, with pricing undisclosed. More information is available in the Premier Farnell announcement and more may eventually appear on the Avnet website.

In this article, Devlin Gualtieri describes his Raspberry-Rx Prescription Reminder project, a network-accessible, the Wi-Fi connected, Raspberry Pi-based device that alerts a person when a particular medication should be administered. It also keeps a log of the actual times when medications were administered.

ENGINEERING TIPS, TRICKS AND TECHNIQUES

The Art of Current Probing
In his February column, Robert Lacoste talked about oscilloscope probes—or more specifically, voltage measurement probes. He explained how selecting the correct probe for a given measurement, and using it as it properly, is as important as having a good scope. In this article, Robert continues the discussion with another common measurement task: Accurately measuring current using an oscilloscope.

Software Engineering
There’s no doubt that achieving high software quality is human-driven endeavor. No amount of automated code development can substitute for best practices. A great tool for such efforts is the IEEE Computer Society’s Guide to the Software Engineering Body of Knowledge. In this article, George Novacek discusses some highlights of this resource, and why he has frequently consulted this document when preparing development plans.

HV Differential Probe
A high-voltage differential probe is a critical piece of test equipment for anyone who wants to safely examine high voltage signals on a standard oscilloscope. In his article, Andrew Levido describes his design of a high-voltage differential probe with features similar to commercial devices, but at a considerably lower cost. It uses just three op amps in a classic instrumentation amplifier configuration and provides a great exercise in precision analog design.

Firms Team Up to Provide End-to-End LoRa Security Solution

Microchip Technology, in partnership with The Things Industries, has announced the what it claims is industry’s first end-to-end security solution that adds secure, trusted and managed authentication to LoRaWAN devices at a global scale. The solution brings hardware-based security to the LoRa ecosystem, combining the MCU- and radio-agnostic ATECC608A-MAHTN-T CryptoAuthentication device with The Things Industries’ managed join servers and Microchip’s secure provisioning service.

The joint solution significantly simplifies provisioning LoRaWAN devices and addresses the inherent logistical challenges that come with managing LoRaWAN authentication keys from inception and throughout the life of a device. Traditionally, network and application server keys are unprotected in the edge node, and unmonitored, as LoRaWAN devices pass through various supply chain steps and are installed in the field.

The Common Criteria Joint Interpretation Library (JIL) “high”-rated ATECC608A comes pre-configured with secure key storage, keeping a device’s LoRaWAN secret keys isolated from the system so that sensitive keys are never exposed throughout the supply chain nor when the device is deployed. Microchip’s secure manufacturing facilities safely provision keys, eliminating the risk of exposure during manufacturing. Combined with The Things Industries’ agnostic secure join server service to the LoRaWAN network and application server providers, the solution decreases the risk of device identity corruption by establishing a trusted authentication when a device connects to a network.

Similar to how a prepaid data plan works for a mobile device, each purchase of an ATECC608A-MAHTN-T device comes with one year of managed LoRaWAN join server service through The Things Industries. Once a device identifies itself to join a LoRaWAN network, the network contacts The Things Industries join server to verify that the identity comes from a trusted device and not a fraudulent one. The temporary session keys are then sent securely to the network server and application server of choice. The Things Industries’ join server supports any LoRaWAN network, from commercially operated networks to private networks built on open-source components. After the one-year period, The Things Industries provides the option to extend the service.

Microchip and The Things Industries have also partnered to make the onboarding process of LoRaWAN devices seamless and secure. LoRaWAN device identities are claimed by The Things Industries’ join server with minimal intervention, relieving developers from needing expertise in security. Customers can not only choose any LoRaWAN network but can also migrate to any other LoRaWAN join server by rekeying the device. This means there is not a vendor lock-in and customers have full control over where and how the device keys are stored.

The ATECC608A is agnostic and can be paired with any MCU and LoRa radio. Developers can deploy secure LoRaWAN devices by combining the ATECC608A with the SAM L21 MCU, supported by the Arm Mbed OS LoRaWAN stack, or the recently-announced SAM R34 System-in-Package with Microchip’s LoRaWAN stack. For rapid prototyping, designers can use the CryptoAuthoXPRO socket board and The Things Industries provisioned parts in samples with the SAM L21 Xplained Pro (atsamd21-xpro) or SAM R34 Xplained Pro (DM320111).

The ATECC608A-MAHTN-T device for The Things Industries, including the initial year of prepaid TTN service, is available in volume production for $0.81 each in 10,000-unit quantities.

Wireless Standards and Solutions for IoT

Protocol Choices Abound

One of the critical enabling technologies making the Internet-of-Things possible is the set of well-established wireless standards that allow movement of data to and from low-power edge devices. These standards are being implemented in a variety of chip- and module-based solutions.

By Jeff Child, Editor-in-Chief

Connecting the various nodes of an IoT implementation can involve a number of wired and wireless network technologies. It’s rare that an IoT system can be completely hardwired end to end. That means most IoT systems of any large scale depend on a variety of wireless technologies including everything from device-level technologies to Wi-Fi to cellular networking.

IoT system developers have a rich set of wireless standards to choose from. And these can be implemented from the gateway and the device side using a variety of wireless IoT solutions in both module and chip form. Some of these are available from the leading microcontroller vendors, but a growing number are IoT-specialist chip and module vendors. Many of today’s solutions combine multiple protocols on the same device, such as Wi-Fi and Bluetooth LE (BLE) for example. We’ll look at each of the major wireless standards appropriate to IoT, along with representative interface solutions for each.

LoRaWAN

Managed by the LoRa Alliance, the LoRaWAN specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks. It meets key IoT requirements such as bi-directional communication, end-to-end security, mobility and localization services.

The networking architecture of LoRaWAN is deployed in a star-of-stars topology in which gateways relay messages between end devices and a central network server. 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 support is included 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.

In a recent LoRaWAN product example, Cypress Semiconductor in June announced its teaming up with Semtech on a compact, two-chip LoRaWAN-based module deployed by Onethinx. The highly-integrated Onethinx module is well-suited for smart city applications that integrate multiple sensors and are in harsh radio environments (Figure 1). Using Cypress’ PSoC 6 MCU hardware-based Secure Element functionality and Semtech’s LoRa devices and wireless radio frequency technology (LoRa Technology), the solution enables a multi-layer security architecture that isolates trust anchors for highly protected device-to-cloud connectivity. In addition, the PSoC 6 MCU’s integrated Bluetooth Low Energy (BLE) connectivity provides a simple, low-power, out-of-band control channel. Cypress claims the PSoC 6 device as the industry’s lowest power, most flexible Arm Cortex-M dual-core MCU with a power slope as low as 22-μA/MHz active power for the Cortex-M4 core. The device works well with Semtech’s latest LoRa radio chip family, which offers 50% power savings in receive mode and 20% longer range over previous-generation devices.

Wi-Fi (802.11)

In systems where power is less of a constraint, the ubiquitous standard
Wi-Fi 802.11 is also a good method of IoT connectivity—whether leveraging off of existing Wi-Fi infrastructures or just using Wi-Fi hubs and routers in a purposed-built network implementation. As mentioned earlier, Wi-Fi is often available integrated with other wireless protocols such as Bluetooth. …

Objenious launched and operates the first LoRa network in France, with more than 4,200 antennas deployed around the country. Leveraging the network know-how inherited from Bouygues Telecom, Objenious now proposes its LoRa network, platform, and services for LPWAN IoT to partners and customers locally and internationally thanks to roaming agreements.

STMicro helps developers by providing tools and software libraries that aid the STM32 MCU-based embedded design as part of its freely available STM32 Open Development Environment (ODE). By integrating Objenious’ network access software on top of the STM32 ODE, developing connected devices is even easier. STM32 Nucleo LoRa kits are now certified and available to developers through ST sales channels.
