Arduino ESP32 Core v3. breaks several Talkie function calls

[chache17]

I installed the Talkie library, to use in ESP32 devices.

I had the ESP32 Core API v.3.0.2 which removed or modified several functions used by Talkie, as seen in ESP's documentation Migration from 2.x to 3.0

This caused evident compilation errors:

Compilation error: exit status 1

After downgrading to ESP32 Core version 2.0.17, Talkie samples started compiling successfully.

It would be great to have compatibility with the newer ESP32 Core API, if possible.

Hi

Did this ever get resolved, as I am having same issue.

hi @Galaxy-Man a fix was committed a couple days ago in this repository Talkie by ArminJo. I haven't had the chance to look into it yet, but hope to do so during this weekend :-)
