Expose ST BlueNRG Bluetooth network coprocessor over UART
Overview
*********
Expose the Bluetooth network coprocessor via UART to a PC to be used
with the ST BlueNRG GUI app. In this case, the main MCU becomes an intermediate level,
and it passes the data between the host (PC) and controller.
Requirements
************
* A board based on BlueNRG BLE module such as :ref:`disco_l475_iot1_board`
* `BlueNRG GUI`_ application installed on your PC
Default UART settings
*********************
It depends on the board default settings for ``zephyr,bt-c2h-uart`` DTS property.
The UART default settings are:
* Baudrate: 115200 bps
* 8 bits, no parity, 1 stop bit
Building and Running
********************
This sample can be found under :zephyr_file:`samples/boards/stm32/bluetooth/interactive_gui` in the
Zephyr tree.
