I am streaming audio from an Android to a PSoC 4 via BLE and sending the received data through the I2S to play it back but the it sounds noisy/static-y. I am able to somewhat hear a sinewave through the noise and when I change the frequency of the sinewave I can hear it change through the speaker attached to the PSoC. However I cannot hear any speech from the speaker, only noise.

I have created a wav file on the Android and it sounds fine. I have tried taking the data from a portion of a file playing a sinewave and directly saving it on the PSoC as an array and playing that instead of the received data but it still has noise/static.

Any help would be appreciated.

Hello

Kindly attach the project. How are you sending .wav file over BLE? Did you test if the .wav file is received at PSoC4-BLE's end in good order?

Thanks,

Hima
