Reply To: Triggering mp3 file over serial

[Michael P. Flaga]

With the fileplayer.ino as is, one does not send “f track002.mp3”. Rather one sends a multi-digit enumeration of the filename as discovered by the List “l” command and the Inter-Character Timeout will delimit the command.

Enter 1-9,f,F,s,d,+,-,i,>,<,p,r,R,t,m,M,g,k,h,O,o,D,S,V,l,01-65534 :
[MPF, I sent “l” to List out directory]
Received command: l
Music Files found :
00001: DING.wav
00002: TRACK001.mp3
00003: TRACK002.mp3

“f” will just simply play track001.mp3.
