Can I use HCI UART(PIN#18 and #19 of BCM20732S module) from the application?

I'm making small pcb and need to shrink # of pins.

So if I can use HCI UART as Peripheral UART, it greatly helps me.

No they cannot be used by the application (except for debug tracing). If another device is connected to the HCI uart and if the RX line is high when the 2073x boots up, it will always enter download mode and so the application will not be initialized/created. And there are no API to reconfigure these pins once the application is initialized.
