After I program my application, I want to disable HCI UART because I don't have any debug traces to print. What should be the line state for CTS? If it is low, the app cannot run after reset because I assume it will be in recovery mode. If I leave it high, the app will run for maybe 10s then stop. Is the app trying to access the HCI UART? What code changes should I make in the app to disable HCI UART? I tried not calling wiced_transport_init() but it doesn't work. I am using the 20719 Q40EVB but the HCI UART is connected to my own test circuit and not the FTDI output.

Hi jhu_3414236,
You will have to call wiced_bt_dev_register_hci_trace() bcoz HCI traces are the communication between host and controller, HCI commands and their response. So it is necessary to define it. You can check the comments about wiced_transport_send_hci_trace() for the same.
Remaining configuration looks good.
