S332 SoftDevice
Pure ANT Stack (Softdevice S212) and ANT/BLE combined stack (Softdevice S332)
Built around a 32-bit ARM® Cortex™-M4F CPU with 512kB + 64kB RAM, Nordic Semiconductor’s nRF52832 multiprotocol SoC offers record breaking performance to the application developer. The nRF52832 incorporates powerful processing with floating point capability, power efficiency through a system of automated and adaptive power management features, a broad suite of analog and digital peripherals, and on-chip NFC™-A tag support.
In collaboration with Nordic Semiconductor, ANT Wireless provides two ANT stacks targeted exclusively for the nRF52 Series SoCs:
• S212 ANT SoftDevice
• S332 Concurrent ANT/Bluetooth® Low Energy (BLE) SoftDevice
SoftDevice Configuration Benefits
• Master Boot Record for over-the-air device firmware update
