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, Zigbee or EasyLink Stack. This chapter will cover the DMM as generally as possible, but when necessary will use the BLE and EasyLink stacks as examples.
