DFPLayer chipset: AB21BP0B953-82A2
SD (TF) card inserted: 4GB
USB flash drive connected: none
Speaker: 4ohm 3W speaker connected to SPK1 and SPK2

Test Date: 2024-06-20

I had to modify TestContinuePlaybackAfterAd with patch provided by [vortigont], but also modified the line
while (trackAd != lastGlobalTrackFinished) {
to
while ((trackAd != lastGlobalTrackFinished) && (lastGlobalTrackFinished == -1)) {

Additionally: everybody who wants to build a little "MP3" player, make sure you understand what those DFPlayer Mini modules are able to do, but also what they will not support...
I'm missing the following features:

• access the SD file from the Arduino
• get the current position of a MP3
• seek to a position of a MP3
• get meta data from MP3 like artist, interpret, title...

I don't know if there is a module or just a decoder on the market which will do all this. Of course the Arduino with the Atmega328 or successors of this architecture is not able to decode mp3 itself in software.
