Overview

This application note (AN99209) provides a technical overview of the Bluetooth Low Energy (BLE) 4.2 features supported by Infineon's PSoC 4 BLE (CY8C4XX8-BL5XX) and PRoC BLE (CYBL11X7X) device families. It covers three major enhancements: LE Data Packet Length Extension for increased data throughput, Link Layer (LL) Privacy for enhanced device security and reduced power consumption, and LE Secure Connections for robust pairing using FIPS-compliant algorithms. The document guides developers on implementing these features using the PSoC Creator IDE, explains the benefits for IoT applications, and details hardware resources such as the DMA controller and flash memory required for over-the-air (OTA) updates.

Use Cases

  • Secure IoT sensor nodes
  • High-throughput wireless data transfer
  • Battery-powered wearables with enhanced privacy
  • Secure pairing for medical or industrial peripherals
  • Over-the-air (OTA) firmware update implementation
