AN91267 introduces you to PSoC^® 4 BLE, an ARM^® Cortex™-M0 based Programmable System-on-Chip (PSoC) that
integrates a Bluetooth Low Energy (BLE) radio system. This application note helps you explore the PSoC 4 BLE
architecture and development tools and shows how easily you can create a BLE design using PSoC Creator™, the
development tool for PSoC 4 BLE. It also guides you to more resources to accelerate in-depth learning about PSoC 4
BLE.
