I'm trying tu use the Acoustic Echo cancellation library from the STM32CubeFunctionPack_SMARTMIC1_V1.0.0 package. However, all the library functions return the ACOUSTIC_LOCK_ERROR error. What am I missing?
I'm using the STM32F405VGT6 device and GCC as compiler. I have linked the libAcoustic_EC_CM4F_GCC_ot.a library that I can find inside the package.
Thank you in advance.
