3.2.12

MLMEPHYResetIndication 

This is an empty function that must be filled by the user, it is called by the MLMEPHYSoftReset, before 
resetting the device.

Prototype

void MLMEPhyResetIndication(void);

Arguments

None

Returns

void

Usage

Fills the logic for this function or leaves it void.

3.2.13

MLMEPHYSoftReset

The MLMEPHYSoftReset function is called to perform a soft reset to the SoC. This function differs from 
previous SMAC where just the radio is reset.
