Wearables
Wearables encompass a broad variety of products that inhabit our person gathering data and feeding data back to us for all sorts of different purposes.
Nordic’s nRF52832 multiprotocol SoC combines an 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96-dB RX sensitivity, with 512kB Flash memory and 64kB RAM. 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.
The S132 SoftDevice was a key feature in the development of the TASER Pulse+, with Nordic’s software architecture including a clear separation between the RF protocol software and Axon’s unique application code. This software separation simplified development and ensured the SoftDevice would not get corrupted when Axon engineers were developing, compiling, testing, and verifying their application code.
“Low power consumption was the main driver of our decision to use Nordic’s nRF52832 SoC in our TASER Pulse+,” says Annie Pratt, Director of Consumer Products at Axon. “The Nordic SoC’s low power modes allowed us to deliver the battery life our customers expected while still providing adequate range.
“We would not have been able to release the product in the required timeline without Nordic's SDK [Software Development Kit]. From a development standpoint, the separation of the SoftDevice from the application code made a lot of sense structurally, keeping the application code straightforward.”
