Adafruit VS1053B MP3 Decoder (Model 1381 V4) not working

I got it to do a local compile using SdFat 1.0.15 and still had the same issues as before. So I tried using WiFi.off() before playing files and then set up the loop() to play all fifteen files. It played all 15 without a hitch and did so three times in a row. The fourth time it stopped playing after the eleventh file but the staus led continued breathing white. That constitutes a HUGE improvement and I believe the hitch on the 11th file may be due to my own coding problem. I will hopefully fix t…

Gen3 devices run at 64MHz and use a different DeviceOS (under the hood) than the Photon or Electron. The ISR handler reads data from the SD card and writes to the Music Maker which can be heavy. You may want to try with Mesh.off() and commenting out the Particle.function() calls.
