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 the only supported stacks are BLE and EasyLink. This chapter will cover the DMM as generally as possible, but when necessary will use these stacks as examples.
