ESP32 + max98357a + online MP3 for Google TTS

[brolly759]

I am trying to use the Google Text to Speech API and generate an MP3 file from Google and then play it on the ESP32 with MAX98357A connected. Someone below wrote code to somewhat do that but I keep getting Watchdog errors or other errors:

https://github.com/oroca/oroca_can
https://www.youtube.com/watch?v=lPwdcfhJnrY

Using this library I can generate the URL's for the MP3 file:
https://github.com/horihiro/esp8266-google-tts

Here is an example Hello World URL to play:
https://translate.google.com/translate_ ... ttsspeed=1

I know the hardware works because I load the bluetooth speakers and it plays fine.

Any help would be great!
