TI DMM 3.20.00 Release Notes
Table of Contents
Introduction
The Dynamic Multi-protocol Manager (DMM) is a software layer that enables a single radio to run multiple wireless protocols concurrently by switching between protocol stacks in real time. DMM allows the developer to manage both protocol stacks effectively and minimize latency.
By using the concurrent multi-protocol application, developers can define system states, determine task priority, and manage multiple wireless stacks concurrently. During execution, the DMM Policy Scheduler allocates radio time for each protocol determined by the priority set in the policy table and the current application states.
While some solutions rely on fixed priority or time-slotted implementations, TI offers a Policy Scheduler solution that is highly customizable and allows priorities to be set dynamically by different application states.
Key features
- Software enabling multi-protocol networks
- Dynamically prioritizes radio usage
- Simplifies concurrent multi-protocol development

Dynamic Multi-Protocol Manager Documentation
The SimpleLink CC13x2 and CC26x2 Software Development Kit (SDK) allows easier product development by combining TI-RTOS, the DMM and the RF protocol stacks in one unified SDK. All DMM sample applications are based off the TI-RTOS Kernel. Key documents needed for DMM application development include:
Installation and Usage
- To build the sample applications with this SDK a supported IDE must be installed (refer to Dependencies below).
- Install the simplelink_cc13x2_26x2_sdk_5_ 20_00_xx installer package on a supported host operating system build machine with Administrator privileges.
- The default install path for Windows is C:\ti\simplelink_cc13x2_26x2_sdk_ 5_20_00_ xx and is referenced as $DMM_INSTALL$ in the documentation.
- Changing the default install path and/or drive letter may require updating project variables. Do not use a space in the install path.
- It is recommended to make a backup of the installation in order to revert modifications to the SDK.

Upgrade and Compatibility Information
Due to changes in the DMM policy table structure, migrating from an SDK version that pre-dates simplelink_cc13x2_26x2_sdk_3_ 10_00_xx requires updating pre-existing application policy tables.
Operating System Support
- Windows 10
- Ubuntu 18.04 64-bit
- macOS Catalina
Dependencies
The DMM sample applications were built and tested with the Integrated Development Environments (IDEs) and listed in the top-level SDK release notes.
Note: Earlier IDE/toolchain versions are not supported and compatibility with newer versions of supported IDEs is not assured.
Device Support
This release supports the wireless MCUs listed in the top-level SDK release notes. The CC2651X3 and CC1311X3 products do not support DMM.
Development Board Support
This release supports application development on the LaunchPads listed in the top-level SDK release notes.
Validation
The DMM sample applications were built & tested with versions of the following Integrated Development Environments (IDEs) and tool chains listed in the top-level SDK release notes:
- Code Composer Studio using the TI C Compiler for Arm
- IAR Embedded Workbench for Arm
This release is for development purposes only.
Versioning
This product follows a version format, M.mm.pp.bb, where:
- M is a 1 digit major number,
- mm is a 2 digit minor number,
- pp is a 2 digit patch number,
- bb is a 2 digit incrementing build counter.
