The collected data is stored on the device and is then relayed on-site to a sales agent or technician’s Bluetooth 4.0 (and later) smartphone or tablet using Bluetooth LE wireless connectivity. From Insigma’s ‘Virtual Hub’ app, the data can then be uploaded to Insigma’s Cloud servers, or sent directly to an IoT gateway (again via Bluetooth LE), from where it is automatically sent to Insigma’s Cloud servers via a GSM or CDMA cellular network. The secure and scalable Cloud platform features alert and artificial intelligence engines enabling device management and configuration, while providing a reporting dashboard to display complex IoT data with simple visualization.
Nordic’s nRF52832 multiprotocol SoC combines a 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 -96dBm RX sensitivity, with 512kB Flash memory and 64kB 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.
“Insigma’s IOT devices rely on non-replaceable batteries, making low power consumption our most important development consideration and therefore the key reason for selecting the Nordic SoC,” says Karan Bakshi, COO at Insigma Inc. “We also selected the nRF52832 SoC for the reliability of the hardware, the competitive price point, and the outstanding support from Nordic’s technical team.”
