TI DMM 2.40.00 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.

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:

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

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.
