Makaio’s ‘Parketeer’ employs Nordic Semiconductor’s nRF52832 SoC to enable smart parking barriers and wirelessly connect with nRF51822 SoC-powered gateway that relays parking spot availability data to the Cloud

Nordic Semiconductor today announces that Makaio, a Bad Homburg, Germany-based smart systems developer has selected both Nordic’s nRF52832 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC), and nRF51822 Bluetooth LE SoC to provide the wireless connectivity for its ‘Parketeer’ smart parking-barrier solution.

Currently the subject of a pilot scheme in the city of Bad Homburg, the smart parking barriers protect parking spaces and charging stations designated for use by electric vehicles (EVs). Each barrier incorporates a nRF52832 SoC providing Bluetooth LE connectivity between the EV driver’s Bluetooth 4.0 (and later) smartphone, as well as between adjacent barriers and a Nordic nRF51822 SoC-based Laird RM186-SM-powered gateway. The barrier-to-barrier connectivity allows a barrier that is in RF range of the driver’s smartphone to instruct an out-of-range barrier to open if the space it protects is the driver’s preference. The gateway relays parking spot availability data to and from the Cloud via Long Range Wireless Area Network (LoRaWAN) technology. The barriers, manufactured by Designated Parking Corp. in the U.S., were originally 868MHz remote control-operated but were upgraded to Bluetooth LE to provide the additional functionality.

In operation, when a driver needs to locate a parking spot and/or charging station, they can use the ‘Parketeer Bad Homburg’ iOS and Android smartphone app to both locate available parking spots, as well as reserve that spot to ensure its availability when they reach their destination. When the parking spot is reserved, the request is sent via the Cloud to the gateway, preventing that parking spot being accessed by another user. As the user approaches an available or reserved parking spot, they connect to the barrier via the Parketeer Bad Homburg app using the Nordic SoC’s Bluetooth LE wireless connectivity. Once payment has been validated, the parking barrier is lowered enabling access to the parking spot. The barrier in turn relays this data to the gateway, which updates parking spot availability data on the server via the Cloud to inform other users of current availability.

When the driver returns to their vehicle and exits the parking space, they press ‘stop parking’ in the app, the barrier is raised, and the customer’s account is billed for the time they occupied the parking spot. From the app the driver can also see the length of time they have been parked at the charging station.

Nordic’s nRF52832 multiprotocol SoC combines an 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The nRF52832 SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The nRF52832 has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs.

“To avoid frequent battery replacement power consumption was a very important factor in the decision to use a Nordic Bluetooth LE SoC,” says Christoph Schramm, Makaio CEO. “The SoC’s ability to perform over-the-air device firmware updates [OTA-DFU] was also really important, because we wanted to avoid disassembling the waterproof barriers every time we introduced a firmware enhancement.

“Nordic’s DevZone is a huge community which provided great support during development. We received helpful answers to our technical queries very quickly.”

Powercast’s ‘PowerSpot TX91503 wireless transmitter’ employs Nordic’s nRF51422 Bluetooth LE multiprotocol solution for wirelessly scheduling power transmissions and monitoring battery status of charging devices

Nordic Semiconductor today announces that Powercast Corporation, a Pittsburgh, PA-based RF wireless power technology company, has selected Nordic’s nRF51422 Bluetooth® Low Energy (Bluetooth LE) multiprotocol System-on-Chip (SoC) for its ‘PowerSpot® TX91503 PowerSpot wireless transmitter’, which the developer claims is the first FCC- and ISED-approved solution to provide far-field wireless power over distance for mobile consumer electronics applications.

Employing a 915-MHz RF signal, the PowerSpot wireless transmitter outputs up to 3W Effective Isotropic Radiated Power (EIRP) (and associated ID data) that can directly power or charge up to 30 portable low-power devices—including fitness bands, wireless headphones, game controllers, hearing aids, and a variety of smartcards—that are fitted with Powercast’s patented embeddable ‘Powerharvester®’ technology.

The Powerharvester solution consists of a proprietary converter chip and a boost converter chip that once integrated in end devices, harvest intentional energy from the PowerSpot wireless transmitter as well as anticipated and ambient RF energy from other RF sources. The chips then convert that energy to DC power that can then be used to charge batteries or directly power the enabled devices.

Acting as the main ‘brain’ of the PowerSpot TX91503 wireless transmitter, the 32-bit Arm® Cortex® M0 CPU-powered Nordic nRF51422 SoC makes the transmitter ‘smart’, configurable, and controllable. For example, it configures and controls the transmitter’s 915MHz oscillator/PA subsection that feeds the power antenna and turns off the transmitter when wirelessly-connected devices are fully charged. The nRF51422 SoC also provides Bluetooth LE wireless connectivity for communication between the user’s end devices and the transmitter to monitor the battery staus of connected devices. This Bluetooth LE wireless connectvity also allows the user to employ a Bluetooth 4.0 (and later) smartphone or tablet to remotely monitor device charge levels and set timers for the transmitter to charge devices during certain periods, for example overnight, via Powercast’s iOS or Android companion app.

The PowerSpot wireless transmitter automatically powers enabled devices it detects within its charging zone and stops charging when no devices are within range. According to the company, the wireless transmitter can charge and power smaller, less power hungry devices—such as smart cards and basic sensors—at distances up to 24 meters while for more power hungry devices like game controllers, headphones, and smartwatches, the most suitable charging range is typically within 30cm. The transmitter itself can be mains- or USB-powered, so the ultra low power consumption of the nRF51422 SoC was important to keep the temperature of the 915-MHz subcircuit low, and enhance the efficiency of wireless power transmission.

Nordic’s nRF51422 SoC is a powerful, highly flexible multiprotocol SoC ideally suited for ANT™ and Bluetooth LE ultra low power wireless applications. The nRF51422 is built around the Arm CPU and includes 256kB/128kB Flash + 32kB/16kB RAM. The SoC is supplied with Nordic’s S310 SoftDevice, an ANT and Bluetooth LE RF protocol software ‘stack’ for building concurrent ANT and Bluetooth LE solutions.

“Rather than needing a separate microcontroller and Bluetooth LE radio, we leveraged Nordic’s highly-integrated hardware and SoftDevice to do everything in a single chip for a much simpler design with elegant circuitry,” says Eric Biel, Principal Engineer at Powercast. “We also needed low power consumption, and here again the Nordic SoC excelled.

“Finally, the pricing and availability of the nRF51422, along with Nordic’s hardware and software support, allowed us to accelerate the development schedule.”

In addition, the user can send individual JavaScript commands to the device without the need to program it. Any errors encountered while running uploaded code can be displayed on the LCD, enabling quicker debugging and faster prototype iterations.

According to Espruino, the use of JavaScript makes writing code much faster and less prone to error than other C-based languages. JavaScript also provides native support for JSON, a common data interchange format for Internet of Things (IoT) devices.

Nordic’s nRF52832 multiprotocol SoC combines an 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The nRF52832 SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications.

“We selected the Nordic nRF52832 SoC-based module because of the SoC’s Bluetooth Low Energy connectivity, low power consumption, large memory, and affordability,” says Gordon Williams, Espruino Director and Lead Engineer.

“And Nordic’s SoftDevice fits in with the Espruino firmware beautifully. The SoftDevice doesn’t try to take over the microcontroller, instead it uses interrupts to execute code only when it needs to. This fits in very well with JavaScript’s event-based architecture and makes it simple to write code that draws minimal power.

“The support on the DevZone and from Nordic engineers has been great. The level of communication has meant designing Nordic solutions into new products has been very simple.”
