Goals for this Training
• Gain a basic understanding of what Bluetooth low energy is, and how
BLE communications work at the link-layer
• Understand Bluetooth low energy access control and data
communication at the top-layers of the protocol stack
• Learn about the current state of BLE from an industry and technology
perspective
• Become familiar with the architecture of CC2540 BLE software,
including the OSAL, HAL, BLE stack, profiles, application, and how all
of the pieces work together
• Be able to get started with the CC2540DK-MINI kit and use BTool to
create a BLE connection
• Be able to open up, build, and debug projects on the CC2540 using
IAR Embedded Workbench and the CC Debugger
• Be able to modify the existing GAP role profiles
• Be able to modify existing GATT attribute profiles, or create new ones
• Understand the sample applications

What is Bluetooth Low Energy?
• A wireless protocol standard overseen by the Bluetooth
Special Interest Group (BT-SIG), comprised of member
companies including Texas Instruments
• The primary new feature added to the Bluetooth standard
in version 4.0 of the Bluetooth core specification (adopted
in June 2010)
• Targeted towards wireless applications with low-power,
low-latency, and low-throughput requirements
• Primarily centered around the mobile phone and PC
ecosystem, but can be used for other applications as well
• Expected to be found in billions of devices over the next
five years
• Not backwards compatible with classic Bluetooth devices
