Notices:
• The Texas Instruments Bluetooth Low Energy software development kit includes all necessary
software to get started on the development of single-mode Bluetooth Low Energy applications using
the CC2540 system-on-chip. It includes object code with the Bluetooth Low Energy protocol stack, a
sample project and applications with source code, and BTool, a Windows PC application for testing
Bluetooth Low Energy applications. In addition to the software, the kit contains documentation,
including a developer’s guide and Bluetooth Low Energy API guide.
• For complete information on the Bluetooth Low Energy software development kit, please read the

Known Issues:
• Use of the NV memory (to save application data or Bluetooth Low Energy Host bonding information)
during a Bluetooth Low Energy connection may cause an unexpected disconnect. The likelihood of this
happening increases with frequent usage, especially when using short connection intervals. The cause
is related to the NV wear algorithm which at some point may cause an NV page erase which can
disrupt system real-time processing. It is therefore recommended that the NV memory be used
sparingly, or only when a connection is not active.
