DF Player Pro, Tutorials, Code And Examples

About the DF Player Pro

The DFPLAYER pro has many good features but the documentation is poorly done. This page tries to fill in the gaps and give you what you need to use it for model railroading.

The documentation starts with  DFRobot Player Pro Wiki – I provides basic tutorials and wiring diagrams.   If you have questions or need help, they refer you to the DF Player Forum –   You are supposed to be able to get help here.  But my experience is that it is a waste of time.

You can take other paths to get help.  There is an active discourse .  Go there first.  You can also write for technical support at

There is another place that people seem to go to get help. Fernion DF Player   There is a comment section filled with unanswered requests for help.

Open the debugging software.

Then select the corresponding serial port in the software

In addition, you must enter “at” to enter the at mode before performing the next steps. After entering at, the serial port will return “OK”, which means that you have successfully entered the at instruction mode.Note that “hex” and “auto enter” are checked
