Bluetooth LE mesh networking accelerates building automation

Wed, Jun 24, 2020

Based on ON Semiconductor’s low power RSL10 system in package (SiP), the RSL10 Mesh platform allows engineers to implement low power mesh networking, using Bluetooth Low Energy (LE) technology, and move quickly towards full deployment, the company claims. Target applications are smart homes, building automation, industrial IoT, remote environment monitoring, asset tracking and monitoring.

The platform consists of two RSL10 mesh nodes and a Strata Gateway for connectivity to the Strata Developer Studio.

Complementing the RSL10 SiP, an array of sensing and indicator devices has been incorporated into the node hardware, including an ambient light sensor (LV0104CS), temperature sensor (N34TS108), magnetic sensors, LED indicators and a triple-output NCP5623B LED driver (for colour mixing). There is also a built-in battery charger either li-ion or li-poly batteries.

The mesh nodes can be configured to take on different roles and functions. The Strata Gateway allows evaluation processes to be carried out using the intuitive Strata Developer Studio. The cloud-connected software enables provisioning of additional mesh and supports firmware-over-the-air (FOTA) updates.

Virtual workspaces for common mesh networking examples, including a smart office, can be used by developers to access sensor data and trigger settings. The energy- efficient RSL10 radio is supported by an Eclipse-based integrated development environment (IDE), a mobile application for provisioning, configuring and controlling a Bluetooth LE mesh network and a Mesh Networking software package which is compliant with the Bluetooth SIG.

“Operational constraints and ease of implementation still represent major challenges,” said Wiren Perera, head of IoT at ON Semiconductor. “Through this new platform we are helping to dramatically accelerate mesh networking development, so that nodes can be more rapidly deployed which push the performance envelope in terms of range, resiliency and power budget.”

ON Semiconductor offers a portfolio of energy efficient, power management, analogue, sensors, logic, timing, connectivity, discrete, SoC and custom devices for automotive, communications, computing, consumer, industrial, medical, aerospace and defence applications.

The company has a network of manufacturing facilities, sales offices and design centres in key markets throughout North America, Europe and the Asia Pacific regions.

Microcontroller increases equipment uptimes, says Maxim

Tue, Jun 23, 2020

Industrial, healthcare and IoT applications can benefit from low power consumption and small form factors, using the MAX32670 microcontroller, says Maxim Integrated.

The Arm Cortex-M4 microcontroller reduces the power consumption and size while increasing the reliability of industrial, healthcare and IoT applications and protects all embedded memory for both flash and SRAM with error-code correction (ECC).

In many industrial and IoT applications, high energy particles and other environmental challenges can threaten to bombard memory and create bit flips during the normal course of operations – especially as process nodes drop to 40nm and below, warns Maxim. This can disrupt microcontroller operation and produce incorrect results. The MAX32670 protects its entire 384kbyte flash memory and 128kbyte SRAM with ECC. With this protection, single-bit errors are detected and corrected by hardware.

Active power consumption is just 40 microW/MHz and the MAX32670 executes commands from flash at 40 per cent lower power than the closest competitive industrial microcontroller, claims Maxim. It is also claimed to be the lowest power device available for battery-operated sensor applications. It is supplied in a 1.8 x 2.6mm WLP and 5.0 x 5.0mm TQFN and claimed to be 50 per cent smaller than the closest competitor, offering reductions in overall size as well as material costs.

The MAX32670 is available now and there is also an evaluation kit, the MAX32670EVKIT#.

Maxim Integrated develops analogue and mixed-signal products and technologies to make systems smaller and smarter, with enhanced security and increased energy efficiency. Maxim’s customers operate in the automotive, industrial, healthcare, mobile consumer and cloud data centre sectors.

Eval kit accelerates BLE SoC development for industrial and smart buildings markets

Tue, Jun 23, 2020

The STMicroelectronics STEVAL-IDB008V1M Bluetooth Low Energy 5.0 (BLE) evaluation platform is intended to accelerate application development with modules featuring the BlueNRG-2 SoC.

BlueNRG-2 supports the Bluetooth 5.0 certification, which allows enhanced security with LE secure connections, power-efficient privacy with Link Layer Privacy 1.2 and up to 2.6 times higher throughput with LE data length extension. The SoC contains an Arm Cortex-M0 core operating at up to 32MHz to handle the Bluetooth stack and application processing. Other features are a 32kHz ring oscillator, 24kbyte RAM and 256kbyte flash program memory. Standby power is low, just 0.9 microA in sleep mode with active Bluetooth stack and there is full RAM retention.

The BlueNRG-M2SA module combines a ceramic antenna, RF balun circuit, and 32kHz crystal oscillator and switch mode power supply (SMPS) inductor to reduce power consumption. The compact module measures 13.5 x 11.5mm.

According to STMicroelectonics, the module greatly reduces engineering costs and enables designers to create wireless devices with minimal RF engineering expertise. BlueNRG-M2SA is qualified as a Bluetooth end product, so additional testing by the customer to complete product qualification is unnecessary, says the company. The modules are pre-certified according to US FCC, Canadian IC, European RED, Japan TYPE radio-equipment regulations and will also meet China SRCC requirements when those are finalised.

The STEVAL-IDB008V1M kit’s board combines the BlueNRG-M2 module with sensors including a MEMS pressure and temperature sensor and motion sensors suitable for nine-axis sensor-fusion library. There is also a low-latency, low-power ADPCM codec, ready to use with BlueVoice middleware for voice over BLE streaming. Arduino R3 connectors are provided, and allow access to all the module’s peripherals and enable users to further extend functionality by adding expansion shields.

The associated development-software package, STSW-BLUENRG1-DK, contains an intuitive BlueNRG-Navigator graphical user interface (GUI) which negates the need for an external programmer or hardware.

The kit also simplifies integration of the BlueNRG-M2SA module with ST’s STSW-BNRG-MESH software. STSW-BNRG-MESH implements the Bluetooth SIG Mesh Profile v1.0 to allow true two-way communication and range-extending mesh networks, for industrial and smart building applications.

Operating temperature range is -40 to +85 degrees C. The module has 5dBm RF output power, enabling it to be powered directly with a pair of AAA batteries or any power source from 1.7 to 3.6V.

The STEVAL-IDB008V1M evaluation kit is available now.
