Dynamic Multi-protocol Manager (DMM)

The Dynamic Multi-protocol Manager (DMM) allows multiple wireless stacks to coexist and operate concurrently. It acts as an arbiter between multiple stacks and the shared RF core resource.

Note

Currently only a subset of stack combinations have been characterized by TI. These include combinations of the BLE5-Stack together with the TI 15.4 or Zigbee Stack. This chapter will cover the DMM as generally as possible, but when necessary will use the BLE and 15.4-Stacks as examples.
