Linkio’s LI052 module employs Nordic’s nRF52832 SoC allowing appliance manufacturers to easily develop Bluetooth Low Energy mesh-connected products for smart-home applications.
“The nRF52832 SoC provided the critical hardware and firmware we required for the module,” says Bruno Deguet, Linkio Co-founder and CTO. “For example, the SoC’s 12 PWM GPIOs ensure the module can control LED smart lights, the powerful processor and generous memory can support our complex mesh software, and the radio’s sensitivity ensures good range. Features such as a full range of programmable on-chip analog and digital peripherals that can operate autonomously to reduce demand on the processor’s resources and save power were also advantageous.
“In addition, Nordic’s S132 SoftDevice’s [RF software protocol ‘stack’] ability to provide concurrent Bluetooth Central and Peripheral role support was key, and the nRF5 Software Development Kit (SDK) with a very large set of examples enabled us to easily experiment with the features we required for our solution.”
Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, supports Bluetooth 5, ANT™ and proprietary 2.4GHz RF software and was the world’s highest performance single-chip Bluetooth LE solution upon launch. The SoC delivers up to 60 percent more generic processing power, offering 10 times the Floating Point performance and twice the DSP performance compared to competing solutions.
The nRF52832 SoC has also been engineered to minimize power consumption and employs a fully-automatic power management system offering processing performance of 58 CoreMark/mA, up to twice as power efficient as competing devices. The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 4.2 qualified stack for building advanced Bluetooth LE applications. The S132 SoftDevice supports Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, provides up to eight connections, and enables concurrent role operation.
