What is the sensor controller?
The sensor controller is a small programmable CPU core available on the SimpleLink CC13xx/CC26xx devices that is highly optimized for low power consumption and efficient peripheral operation.
The sensor controller can perform simple background tasks autonomously and allow the System CPU and MCU to remain in sleep mode. This allows for power optimization based on events such as wake on temperature, wake on touch, and beyond.
Concurrent multi-standard operation
Meet the Dynamic Multi-protocol Manager (DMM)
The Dynamic Multi-protocol Manager (DMM) is a software layer that enables a single radio to run multiple wireless protocols concurrently by switching between protocols stacks in real time. This layer allows the developer to determine a custom protocol priority for every possible state of the system, managing both protocol stacks effectively and minimizing latency.
How does it work?
The concurrent multi-protocol application developer can utilize the DMM Policy Table and the DMM Policy Scheduler to define system states, determine task priority, and manage multiple wireless stacks concurrently. Protocols are allocated radio use by priority, which is determined in the policy table and executed by the policy scheduler.
While some solutions rely on fixed priority or time-slotted implementations, TI's offers a Policy Scheduler solution that is highly customizable and allows priorities to be set according to every possible system state.
Example use case: building security system
Security panel running BLE and 15.4 Stack Sub-1 GHz concurrently receives an alarm message from a door sensor when the door has been opened.
The Sub-1 GHz alarm message pre-empts a BLE task in order to deliver the alarm message. Later, the BLE task resumes and the user’s smartphone is updated with the alarm status.
