CC256x TI's Bluetooth Stack

From Texas Instruments Wiki

Return to CC256x Main Wiki

Introduction[edit]

  • TI’s Bluetooth stack is upper layer Bluetooth Protocol Stack implementation. The TI’s Bluetooth stack supports the MSP430, MSP432, Tiva and STM32 devices using either the CCS or IAR tool chains. The TI’s Bluetooth stack includes the core protocol stack with Low Energy support (BLE), the Serial Port Profile (SPP), the Generic Attribute Profile (GATT) and various Low Energy services. The software can be obtained from here
  • The TI’s Bluetooth stack is a software solution that resides above the Physical HCI (Host Controller Interface) Transport Layer and extends through the Logical Link Control and Adaptation Protocol (L2CAP) and the Synchronous Connection-Oriented (SCO/eSCO) Link layers. In addition to basic functionality at these layers, TI’s Bluetooth stack provides implementations of the Service Discovery Protocol (SDP), Radio Frequency serial COMMunications port emulator (RFCOMM), and several of the Bluetooth Profiles. Program access to these layers, services, and profiles is handled via Application Programming Interface (API) calls.

CC256XCMSP432BTBLE_Solution


To work with the CC2564C device with supported Bluetooth 4.2 support, please visit the MSP432 Getting Started Guide.
The TI Dual-mode Bluetooth Stack for the CC2564C on MSP432 SDK can be found here (CC256XCMSP432BTBLESW).











CC256XMSP432BTBLE_Solution


To work with the MSP432P401R Launchpad board Texas Instruments provides the CC256x Booster Pack (BOOST-CC2564MODA)
with TI Dual-mode Bluetooth Stack on MSP432 SDK (CC256XMSP432BTBLESW).
For older CC256x variants such as the CC2564B, visit the following Getting Started Guide.




To demonstrate Voice and Audio use cases, the CC3200 Audio Booster Pack (CC3200AUDBOOST) may be used (see below).

MSP430 EVM[edit]

Demo Setup Overview
The TI Bluetooth stack includes sample applications directory with source code which demonstrates the use of the TI’s Bluetooth stack.
These sample applications are a simple, command line application which will display a list of available commands.
Input and Output can be utilized by plugging in the MSP430 Experimenter board Serial to USB debugging connector to a PC.
 For platform setup and Demo information please visit the MSP430 Getting Started Guide.

STM32F4 EVM[edit]


STM32-Discovery_CC256XQFN-EM_STADAPT
The CC2564C device comes with Bluetooth 4.2 support and the TI Dual-mode Bluetooth Stack on the STM32F4 SDK (CC2564CSTBTBLESW).
Please visit the STM432 Getting Started Guide.
To work with the STM32F4 EVM board Texas Instruments provides the CC256xBEM Bluetooth Adapter Kit and TI Dual-mode Bluetooth Stack on STM32F4 SDK (CC256XSTBTBLESW). For older CC256x variants, visit the following Getting Started Guide.
Input and Output can be utilized by plugging in the STM3240G-EVAL microUSB connector to a PC.




For hardware configuration of the boards visit the CC256xEM Bluetooth Adapter Kit User Guide








Architecture Overview[edit]


TI’s Bluetooth stack is designed such that the application programmer does not have to be aware of implementation details. To satisfy this requirement, TI’s Bluetooth stack is designed based on the following principles:

  • Fully thread safe (threaded environments)
  • Asynchronous event notification
  • Fully Re-entrant
  • Entirely self contained (threaded environments)


BluetopiaArchitecture.jpg


  • The first item, being thread safe, means that multi-threaded applications can make TI’s Bluetooth stack calls without the need for synchronization events to guard access to the Bluetooth Protocol Stack (unless the application is designed such that it requires its own synchronization).
  • The second item, aids multi-threaded applications in that making a TI’s Bluetooth stack API call does not block the calling thread for long periods of time and requires no polling. TI’s Bluetooth stack is designed such that the application is notified of asynchronous events via application installed callbacks. These callbacks are called at the time an event occurs.
  • The third item, re-entrancy, means that all TI’s Bluetooth stack API calls are safe to be called from the asynchronous callback functions. This simplifies application development by not requiring the programmer to define messages or events based upon stack events (and having to notify the application of these events).
  • The final item, entirely self contained, means that the programmer does not have to call any functions to cause TI’s Bluetooth stack to function. An example of this would be a function to ‘pump’ a state machine. TI’s Bluetooth stack requires no such actions when operating in threaded environments. When TI’s Bluetooth stack is operating in a single threaded environment, functions will need to be called to periodically to process the Bluetooth state machine.



Profiles, Protocols and Services[edit]

Bluetooth SIG Adopted Specifications

NoteNote: The MSP432, STM32 and AM335x Bluetooth Stack software each have two releases, one of which is for the CC256X device variants, while the other can be used with the new CC2564C release. The MSP432 and STM32 columns below reflect these versioning differences as (CC256XBTSTACK/CC2564CBTSTACK).
