Note! E2EAMS and E2APR are new commands that replace the

funtionality offered by the EALR, EAMS, EARS and ELAM

commands. Use the new commands in new applications. The old

commands are included for compatibility.

4.1 AT*E2EAMS Ericsson M2M Audio Profile Modification

This command allows the modification and configuration of the current

audio profile. An audio profile is a set of data which uniquely defines

the way in which the audio paths, gains, DSP algorithms and switch

setting are configured. There are several audio profiles available in

non-volatile storage, and the current profile can be modified by use of

the AT*E2APR command.

The AT*E2EAMS command allows the user to:
