Hi,

I'm currently evaluating the CYBT 343026 BT/BLE module and have a question about the PCM audio interface. In the specification for the chipset used (CYW20706 Datasheet ) in section 1.7 it indicates that the PCM interface can run in TDM mode with 1, 2, 4, 8 or 16 slots. I could not find a way to configure how many slots should be present and which slots the module should use within the WICED APIs. Have I missed something?

Thanks

Nigel

WICED does not support PCM use by application directly. PCM/I2S are used internally by the BT FW for BT (SCO/A2DP) audio routing.

Even internally, PCM is used only in I2S mode.
