Hi,

Our customer wants to use HCI UART for communication to external MCU. For this, following blog explains how to use raw mode of HCI UART.

How to Use HCI Raw Data Mode in CYW20706 - KBA225970.

But I have a question.

When I use HCI RAW mode, flow control between 20706 and external MCU should be used but I can't see related APIs. I know flow control for PUART is supported in wiced_hal_puart.h but I am not sure if flow control for HCI UART is supported.

Q) Is it possible to use flow control of HCI UART in application layer?

Thanks,

Liam

Hi,

CTS/RTS on HCI UART are hardware driven and cannot be controlled from software.

Thanks,
