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