Nordic’s nRF52840 Bluetooth 5/Bluetooth LE SoC supports gateway-free, long-range wireless connectivity between Sikom’s ‘Bluetooth Thermostat EP’ and smartphone
Nordic’s nRF52840 Bluetooth 5/Bluetooth LE SoC is Nordic’s most advanced ultra low power wireless solution. The SoC supports complex Bluetooth LE and other low-power wireless applications that were previously not possible with a single-chip solution. The SoC combines the Arm processor with a 2.4GHz multiprotocol radio architecture featuring -96dB RX sensitivity and an on-chip PA boosting output power to a maximum of 8dBm. The SoC is supplied with the S140 SoftDevice, a Bluetooth 5-certified stack which supports all the features of the standard and provides concurrent Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles.
“The nRF52840 is a cutting-edge platform with outstanding performance. It provides a lot of freedom in design and functionality of our thermostat, while simultaneously keeping costs down,” says Axel Jacobsen, CEO of Sikom.
“The most important features for us are the microprocessor capability and memory capacity, which enable swift development of complex applications running on a single core, without ‘hitting walls’ and wasting time on fine-tuning the performance or sacrificing functionality. The Nordic SoC’s radio sensitivity and support for Bluetooth 5 technology’s long-range feature also provides superior connection stability in difficult environments, significantly boosting range.
“The SoftDevice stability, Bluetooth 5, RTOS and multiprotocol support, and Software Development Kits (SDK) with drivers and example applications are all important features of the Nordic SoC,” adds Jacobsen.
“Nordic also offers an excellent support team with fast response and easy-to-use technical documentation, reference designs and tools, and hardware samples as required.”
