Compact Arm-Based IoT Protocol Conversion Gateway has Crypto Chip

By Eric Brown

Advantech has launched a rugged “WISE-710” IoT protocol gateway that runs Linux and its WISE-PaaS/EdgeLink stack on the i.MX6 DualLite and offers a crypto chip, 2x GbE, mini-PCIe, 3x serial/CAN, DIO, and optional analog and temperature interfaces.

Advantech previewed its WISE-710 gateway back in May and has now announced its release on Design World. The 100 x 70 x 36mm “industrial protocol gateway” runs Ubuntu 16.04 or the optional Yocto 2.1 on the tried-and-true NXP i.MX6 DualLite, which has shipped on earlier Advantech embedded computers such as its UBC-220.


 
WISE-710 on the desktop and wall

The WISE-710 can optionally be loaded with Advantech’s WISE-PaaS/EdgeLink protocol-conversion software, which supports more than 200 communication protocols including Modbus, OPC-UA, MQTT, and IEC-60870-5-104 “to enable data collection from legacy devices,” says Advantech. WISE-PaaS/EdgeLink offers LWM2M client and Node ID technology and supports user-defined data acquisition periods for each input interface, “thereby reducing the volume of data transmitted and stored on the cloud.”

Another novelty here is a Microsoft Azure-certified Microchip ATECC508A secure element, which is also said to ensure compliance with Amazon AWS security regulations. The crypto chip offers embedded key encryption, authentication, and anti-tamper technology for IoT aggregation and prevents “unauthorized firmware updates and proliferation on the cloud,” says Advantech. (Coincidentally, we just covered a USB armory Mk II SBC that offers a very similar ATECC608A chip.)

The 1GHz, dual-core -A9 i.MX6 Dual is accompanied by 1GB DDR3, 8GB eMMC, and a microSD slot that supports data logger microSD cards. There are dual (non-native) GbE ports and a full-size mini-PCIe slot with optional WiFi, 3G/4G LTE (with SIM slot), and optional antennas. The announcement also mentions an optional NB-IoT wireless module, but it was not included in the accessory list.

The WISE-710 is further equipped with a micro-USB 2.0 host port plus RS232/485 and RS485/CAN serial ports and an internal RS485 interface. The system integrates isolated 4-in/4-out DIO with “wet contact & dry contact by switch,” as well as a modular interface that supports one of two additional options: 8x analog inputs with 4x digital inputs or 4x RTD (Resistance Temperature Detector) inputs with 4x thermocouple channels.

There’s a 24VDC terminal block input and low 5W typical power consumption, as well as -20 to 55°C support with 10 ~ 95% RH @ 40°C, non-condensing humidity resistance. You also get 2Grms vibration resistance per IEC 60068-2-64 and 10G shock resistance compliant with IEC 60068-2-27.

Multiple LEDs are included and you can choose from wall, DIN-rail, and pole-mount options. The detail view also shows a GND connection and a QR code interface.

Further information

The WISE-710 is available now at an undisclosed price. More information may be found on Advantech’s WISE-710 product page.

Pre-Provisioned Solutions Provide Scalable IoT Security

Microchip Technology has introduced what it claims is the industry’s first pre-provisioned solution that provides secure key storage for low-, mid- and high-volume device deployments using Microchip’s ATECC608A secure element. Microchip’s Trust Platform for its CryptoAuthentication family enables companies of all sizes to easily implement secure authentication.
Microchip’s Trust Platform consists of a three-tier offering, providing out-of-the-box pre-provisioned, pre-configured or fully customizable secure elements, allowing developers to choose the platform best suited for their individual design. As the first solution to provide ready-to-go secure authentication for the mass market, the first tier–Trust&GO–provides zero-touch pre-provisioned secure elements with a Minimum Orderable Quantity (MOQ) as low as 10 units.

Device credentials are pre-programmed, shipped and locked inside the ATECC608A for automated cloud or LoRaWAN authentication onboarding. In parallel, corresponding certificates and public keys are delivered in a “manifest” file, which is downloadable via Microchip’s purchasing e-commerce store and select distribution partners. In addition to saving up to several months of development time, the solution significantly simplifies provisioning logistics, making it easy for mass market customers to secure and manage edge devices without the overhead cost of third-party provisioning services or certificate authorities.

As the number and types of connected devices proliferates, market fragmentation and security vulnerabilities in the Internet of Things (IoT) have created significant challenges for developers. Hardware-based security is the only way to protect secret keys from physical attacks and remote extraction, but extensive security expertise, development time and costs are required to configure and provision each device.

With companies producing anywhere from hundreds to millions of connected devices per year across the globe, scalability of architecture can be a major barrier to deployments. Manufacturers typically have only been able to support configuring and provisioning for high-volume orders, leaving companies with low- to mid-sized deployments with low performing options.

With the ability to authenticate to any public or private cloud infrastructure, Microchip’s Trust Platform is also flexible and customizable. For customers who want more customization, the program includes the TrustFLEX and TrustCUSTOM platforms. The second tier in the program, TrustFLEX, offers the flexibility to use the customer’s certificate authority of choice while still benefiting from pre-configured use cases.

These use cases include baseline security measures such as Transport Layer Security (TLS) hardened authentication for connecting to any IP-based network using any certificate chain, LoRaWAN authentication, secure boot, Over-the-Air (OTA) updates, IP protection, user data protection and key rotation. This reduces the time and complexity involved in customizing the device without requiring customized part numbers. For customers who would like to entirely customize their designs, the third tier in the program – TrustCUSTOM – provides customer-specific configuration capabilities and custom credential provisioning.

Microchip worked with Amazon Web Services (AWS) to enable a straightforward and simplified onboarding process into AWS IoT services for products designed with all variants of the Microchip Trust Platform.

The ATECC608A provides Common Criteria Joint Interpretation Library (JIL) “high”-rated secure key storage, giving customers confidence that devices implement industry-proven security practices and the highest level of secure key storage. With hardware-based root of trust storage and cryptographic countermeasures, the device protects against the widest classes of known physical attacks. Microchip’s secure manufacturing facilities safely provision keys, ensuring that keys are never exposed to any party during provisioning or the lifetime of the device.

The ATECC608A can be paired with any microcontroller and microprocessor. For rapid prototyping of secure solutions, designers can use the Trust Platform Design Suite, which includes:

  • A guided “use case tool”
  • Executable Python tutorials running on Jupyter notebooks
  • C code examples for each use case
  • A “secret exchange” utility
  • The Trust Platform hardware development kits

Devices in Microchip’s Trust Platform are available in volume production today with the following minimum order quantities (MOQ):

  • Trust&GO for TLS (ATECC608A-TNGTLSx-B): $1.20 with a MOQ of 10 units*
  • Trust&GO for TLS (ATECC608A-TNGTLSx-G): $0.77 with a MOQ of 2000 units*

Bluetooth LE Solar Dev Kit for IoT Taps Nordic Semi’s BLE SoC

Nordic Semiconductor has announced that PowerFilm, a company specializing in custom solar solutions, employs Nordic’s nRF52832 Bluetooth Low Energy (Bluetooth LE) SoC in its “Indoor Solar Development Kit with Nordic BLE” for IoT developers, engineers and hobbyists looking to power electronics by harvesting indoor light energy. Once harvested, the energy is stored in a rechargeable battery or capacitor bank.

The development kit simplifies the design process for OEMs incorporating indoor solar energy in Bluetooth LE devices, with applications including smart home, building automation, inventory and retail management, asset tracking, and industrial monitoring. In addition to the Nordic SoC, the plug and play kit incorporates an onboard energy harvester/power management IC and indoor solar panels. In operation, the nRF52832 SoC automatically connects to the power when energy is available—enabling Bluetooth LE operation of the solar-powered device—before disconnecting when the stored energy is depleted.

The high performance indoor solar panels are able to sustain Bluetooth LE operation even in dimly lit indoor environments such as those typically seen in warehouses and industrial plants, thanks in part to the ultra-low power characteristics of the Nordic SoC. The nRF52832 has been engineered to minimize power consumption with features such as the 2.4 GHz radio’s 5.5 mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80% compared with Nordic’s nRF51 Series SoCs.

The development kit’s onboard capacitor charger provides two key benefits: First, it enables applications that don’t need the extra storage capacity to operate without a battery; and second, it charges the capacitors directly from the solar panel, without any conversions, which boosts performance over a standard energy harvesting power management integrated circuit.

Nordic’s nRF52832 multiprotocol SoC combines a 64 MHz, 32-bit Arm Cortex M4F processor with a 2.4 GHz multiprotocol radio (supporting Bluetooth 5, ANT, and proprietary 2.4 GHz RF protocol software) featuring -96-dB RX sensitivity, with 512 KB Flash memory and 64 KB RAM. The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.

Cloud-Based OTA Manager for IoT is Free For Up to Three Devices

By Eric Brown

UpSwift is offering a free lifetime subscription to makers and developers who want to manage up to three Linux-based devices with the UpSwift cloud-based IoT management and micro-updating platform.

Israeli startup UpSwift announced its cloud-based UpSwift IoT management and update service for Linux-based IoT and embedded devices in Jan. 2018 and over the last year has deployed it in “multiple companies.” The company is now announcing a new “Prototyping” offering that provides a free lifetime subscription for “maker/developers” who want to manage up to three Linux devices.

UpSwift is a lightweight, application layer micro-update OTA solution with automatic rollbacks, filesystem component updates, and an encryption-based in-transit update security feature. The system is optimized for constrained devices and communications pipelines by reducing data transfers and memory usage.


 
UpSwift management screen (left) and maps view
(click images to enlarge)

Other features include device remote control using web ssh, map views for pinpointing deployments, application monitoring and diagnostics, and sending application logs. UpSwift enables the setting of update triggers as well as monitoring a JSON file to check whether a micro-update is in progress. You can also change parameters such as device communication cycle settings.

Device requirements include Linux systems running on ARM, x64, and x86 platforms equipped with the apt package manager and Systemd service manager. The menu-driven program also supports Bash commands.

Security is enhanced because no servers are used on the client side, says UpSwift. For additional security and privacy, only the device MAC is used in the service process. In addition, disk monitoring tests are used to “recognize any read or write changes of files in the file system to make sure there is no leakage of data from the device.”

Other commercial OTA update solutions for Linux gizmos include Mender. In addition, Ubuntu Core’s snap package management mechanism also provides transactional updates. There are a variety of open source smart update solutions, but without the cloud management functions offered by a service like UpSwift. For an overview, check out this summary of a presentation by Intel’s Patrick Ohly at the 2017 Embedded Linux Conference.

Further information

The free lifetime UpSwift subscriptions for makers and developers for up to three Linux devices are available now. No pricing was available for the standard monthly and yearly subscriptions. More information may be found at the UpSwift website.

Cattle Health Monitoring System Taps Semtech’s LoRa Technology

Semtech has announced that ITK, a French supplier of IoT-based smart agriculture applications, has developed a new cattle health monitoring solution based on Semtech’s LoRa devices. The FarmLife smart agriculture service and its LoRa-enabled sensors detect cattle estrus, drive improved nutrition and predict the onset of disease to help ranchers better monitor their herd.

According to ITK, LoRa devices’ flexibility in deployment makes a key difference for connecting animals and offers the potential for a significant return on investment (ROI). ITK’s solution provides ranchers with tangible, actionable data on the health of their herd to remove variables from ranching and create productive, efficient and profitable ranches.

Offering a flexible solution for the smart agriculture vertical, Semtech’s LoRa devices create applications that help minimize waste, maximize yield, reduce expenses, and offer farms and ranches an opportunity to operate as efficiently as possible. ITK’s LoRa-based sensors deploy simply through a collar equipped to each animal. The collar is non-invasive and immediately begins reporting data on the cow’s health upon deployment. Ranchers monitor their herd from this unique LoRa-based device, which provides the benefits of four value added services: Heat’Live for heat detection, Feed’Live for nutrition optimization, Time’Live for animal welfare, and Vel’Live for calving detection. These services are available through ITK’s FarmLife Cloud platform. In total, deploying ITK’s solution costs less than 30€ per animal annually.

In addition to the 300,000 cows already monitored in Europe, approximately 20 ranches have deployed ITK’s FarmLife platform in North America, connecting cows to the Cloud through network connectivity from X-TELIA, a leading Canadian network provider. Following this initial deployment, farmers claimed they received an ROI in less than a year through an increase in ranch productivity and efficiency. X-TELIA and ITK plan to continue the rollout of this smart agriculture solution in the Canadian market, adding ITK’s San’Phone cattle health monitoring service and its Thermo-bolus sensor to connect up to 2.4 million cows in the coming months.

LTE, LTE-M, NB-IoT Antenna Serves Embedded Surface-Mount Needs

Linx Technologies, has introduced its Splatch SP610 surface-mount embedded antenna for LTE cellular applications, including LTE-M (Cat-M1) and NB-IoT cellular Internet of Things (IoT) uses. Measuring a compact 10 mm by 40 mm and just 2.8 mm high, the surface-mount SP610 antenna achieves high performance in the more challenging 700 MHz bands as well as common higher-frequency bands.  Like all of Linx’s Splatch antennas, the SP610 is designed to accommodate close proximity effects from interferers such as other solution components or the human body. This combination of small size and robust performance makes it especially well-suited for cellular IoT applications.

The SP610 targets North American cellular carriers for all LTE applications with excellent performance in the 700 MHz frequency bands favored by Verizon, AT&T and T-Mobile, while providing strong performance in 800 MHz, 900 MHz and > 1 GHz bands used by carriers, worldwide. Additionally, the SP610 provides full band support for LTE-M and NB-IoT applications which use sub-1 GHz frequencies to achieve longer range, and often use frequency band edges to avoid other cellular traffic.

The SP610 is available today in tape and reel packaging via Linx Technologies’ distributor and manufacturer representative networks.
