Not sure if this is a patch or fix, but I started increasing the timeout parameter in the serial open statement and now, it doesn't give the error
serial.serialutil.SerialException: read failed: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
I went up to 20 before it stopped giving an error, started at 2. I suppose, that the chip on the MP3 board doesn't support a very fast serial port.
This just stopped the above error. I still have work to do to get the whole return code back. At this point, all I get back are zeros, no leading or trailing information like the documentation suggests.
