I'm trying to call the command described in the documentation for the module.

On the SD card there is a folder "02test" in the root. This folder contains sound files
01 test.mp3
02 test.mp3
and so on.
When I enter the command AT+AJ/02*/01*.?? I get ER+6. What am I doing wrong, please tell me those who know.

That's the name of your folder?

Maybe try:

01testintheroot

This information will probably not be useful to others. But the decision was that I myself was mistaken.
AT+AJ/02*/01*.???
the command will work if sent via Serial.println(AT+AJ/02*/01*.???);
If directly to the port, then you need to select NL&CR in the menu next to the baud rate selection. In general, both line transition and carriage return need to work.
