StanceBeam Striker uses a fully rechargeable 100mAh battery that provides battery life of approximately six hours of game play before recharging in a portable charging cradle, 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 SoCs.
Nordic’s nRF52832 multiprotocol SoC combines the 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. Nordic’s unique software architecture provides a clear separation between the RF protocol software and StanceBeam’s application code, simplifying the development and testing process and ensuring the SoftDevice doesn’t become corrupted when developing, compiling, testing, and verifying application code. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.
“While designing StanceBeam Striker and comparing various Bluetooth LE chipsets available in the market, we realized Nordic’s nRF52832 SoC was the best fit for the product due to its compact size, power consumption, and the CPU capabilities needed for this type of complex application,” says Ishwinderpal Singh, Co-Founder and CTO of StanceBeam.
“The top driver for using the Nordic SoC was the stability of the Bluetooth LE stack. We developed our own application code and Nordic’s SDK [Software Development Kit] was of great assistance in developing and prototyping the use cases we wanted to implement. The technical information, documentation, and reference designs provided by Nordic made life much easier for our designers.”
