Turnpike Group’s Fantom smartband employs Nordic’s nRF52832 SoC to wirelessly deliver wearer in-game live stats via Cloud-connected smartphone app.
Nordic’s nRF52832 SoC provides low latency Bluetooth LE wireless connectivity between the Fantom smartband and an Android- or iOS-compatible Fantom app on the user’s Bluetooth 4.0 (and later) smartphone, which in turn allows bidirectional data exchange with any Cloud-based platform used by the professional sports club, its sponsor, or other partners.
The Fantom smartband incorporates an 80mAh battery providing approximately two days of battery life between recharge, thanks in part to the low power characteristics of the Nordic SoC. 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 SoC. This battery cycle time can also be dynamically adjusted by balancing screen time based on the application.
Nordic’s nRF52832 multiprotocol SoC combines an Arm processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96-dB RX sensitivity. The nRF52832 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.
“We initially chose Nordic’s nRF52832 SoC for its power to performance ratio, but quickly realised that the extensive firmware resources provided by Nordic are what set them apart from the competition,” says Björn Ögren, Founder and CEO of Turnpike Group.
“This was our first project with Nordic and we definitely see a strong partnership going forward. Both the community and direct support channels have been excellent, and we feel that the large user base on the nRF Series devices today really helps products like ours get off the ground.”
