SELINT 2
AT#ECHOCFG=<par_1>
[,<par_2>[,…,<par_N>]]
Set command writes values in echo reducer parameters. It is not allowed if
active audio profile is 0.
The module responds to the set command with the prompt '>' and waits for
the data to send.
Parameters:
<par_1>
0 – configure all parameters, module awaits 39 values
1,2,..,39 – configure single parameters, module awaits 1 value
<par_i> with i = {2;N}
1,2,..,39 – configure every parameter specified
After '>' to complete the operation send Ctrl-Z char (0x1A hex); to exit
without writing the message send ESC char (0x1B hex).
Data shall be written in Hexadecimal Form with 4 digits for every
<par_i> value provided by set command.
If data are successfully sent, then the response is OK.
If data sending fails for some reason, an error code is reported.
Parameters can be saved in NVM using AT#PSAV command and are
available for audio profiles 1,2,3. For audio profile 0 the values are fixed.
Note: Configuring single parameters, it is allowed to enter a maximum of
32 parameters.
Note: the default configuration is targeted for almost all common acoustic
echo scenarios; if further tuning is needed the customer can change by
oneself only the following parameters:
<par_14>
0..32767 - factory default value is 18384
Additional gain: increasing this parameter average echoes are more
attenuated
<par_15>
0..16384 - factory default value is 2000
Total gain lower limit: increasing this parameter small echoes are more
attenuated
