  • Page 12: Development Tools

    Getting Started With EZ-BLE™ PRoC™ Module Development Tools Cypress supports the EZ-BLE PRoC Module with high-quality software tools and development kits. They provide access to a suite of world-class Integrated Design Environments (IDEs). PSoC Creator is a single IDE to develop application code and then build, debug, and deploy an embedded design.

  • Page 13: Bluetooth Low Energy Component Software

    Figure 62. CySmart, along with a Cypress BLE dongle, acts as a master device. The tool supports the Bluetooth 4.1 specification and can connect to any Bluetooth 4.1 or 4.0 enabled BLE peripheral devices. Comprehensive test scenarios can be created by configuring the scan, connection and security parameters.

  • Page 14: Cysmart Mobile App

    The kit also contains a BLE USB dongle that acts as a BLE master and works with the CySmart application to provide a BLE master emulation platform on non BLEWindows systems. Cypress also provides an adapter board for the EZ-BLE PRoC Module to evaluate and develop with the Cypress module without the need to develop custom hardware.
