CC3200AUDBOOST: Pheripheral bidirectional audio example

CC3200AUDBOOST: Port of Peripheral bidirectional audio example on CC26X2R1

Tool/software:

Hi, I am trying to execute the Peripheral bidirectional audio on a custom-designed board using the SimpleLink audio plugin version 3.30.00.06 with the SimpleLink CC13x2/26x2 SDK version 7.40. The project compiles and works fine until we try to decode Opus; it returns a BAD_ARG error during Opus decoding. However, if we use SimpleLink CC13x2/26x2 SDK version 3.30.00.03, it works fine.

The Opus library used in this project is the precompiled version already included. Is there any limitation with this library that prevents us from using it with the newest SDK?

Also, I have noticed different values for variables depending on the SDK we are using, despite following the same steps in both projects.

    Hi,

    I don't have this hardware and plugin to test with but you moved from CC3200 to CC13x2/26x2, latest version.

    Most likely the pre-compiled libraries where compiled with a different compiler (for sure not TI-Clang). I am not sure it is supposed to work if you mix two compilers. Does it say which compiler was used to compile the Opus library?
