i posted that i've tested the pvvx version over several hours on the ESP-01 without problems. Now i have flashed the same binaries to an esp-12E module with 4MB flash (nodemcu 1.0?) and i can hear only a few seconds to the music, then nothing for about a minute -> one second music -> 1min nothing ...
should i change something before compiling it, to run the code one the 4MB version as good as on ESP-01?
EDIT: i restarted my FRITZ!Box Wifi Router and everything is fine -> works great! Thanks again!
