Hong Kong, China, January 11, 2018 /ChinaNewswire.com/ - DaBuZiDuo’s XOSS SPRINT uses Nordic’s nRF52832 SoC to provide workout data analysis, offline maps, GPS navigation, and interoperability with third-party sensors
Nordic Semiconductor today announces that Shanghai, China-based cycling technology company, DaBuZiDuo, has integrated Nordic’s nRF52832 multiprotocol Bluetooth#174; Low Energy (Bluetooth LE)/ANT+#8482; System-on-Chip (SoC) into a multifunction bike computer.
Named ‘XOSS SPRINT’ the computer offers cycling enthusiasts a comprehensive range of performance benefits including professional workout data recording and analysis, global offline map rendering, and powerful GPS route navigation. The Bluetooth LE wireless connectivity enabled by the Nordic SoC then allows users to access key riding information via the ‘Xingzhe’ partner app on their compatible iOS or Android smartphones. The Xingzhe app already has nearly 10 million registered users.
In addition, DaBuZiDuo’s proprietary “Fusion” Dual Connection technology allows users to choose between Bluetooth LE and ANT+ wireless connectivity when linking complementary third-party devices to their XOSS SPRINT. Leveraging the nRF52832 SoC’s 2.4GHz multiprotocol radio and Nordic’s flexible RF software protocol “stack” (“SoftDevice”), XOSS SPRINT supports peripherals such as a power meter, heart rate monitor, and cadence and speed sensors.
The device features up to nine customized, high-resolution data displays and a 2.7-in (69-mm) reflective Memory LCD screen which the company claims supports good readability in sunlight, while its lithium polymer battery provides 37 hours of continuous GPS recording and three months or more of standby time – achieved in part by the Nordic SoC’s ultra low power capabilities.
Nordic’s nRF52832 mulptiprotocol SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines an 64MHz, 32-bit ARM#174; Cortex#174; M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT#8482;, and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. When launched, the SoC was the world’s highest performance single-chip Bluetooth LE solution.
The SoC is supplied with Nordic’s S332 SoftDevice, a combination Bluetooth 5-certifed/ANT RF software protocol stack for building advanced Bluetooth LE and ANT applications. The S332 SoftDevice supports Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.
“The nRF52832 SoC meets the important power consumption requirements of the XOSS SPRINT, and the multiprotocol compatibility significantly simplifies our hardware design,” says Mao Feng, Hardware Leader at DaBuZiDuo.
“The ability to use Nordic’s Software Development Kit [SDK], along with the clean separation between the S332 SoftDevice and our own application code, supports the operation of the third-party real-time operating system [RTOS]. This impressive software protocol stack design adds great convenience to code preparation and maintenance.”
