Bluetooth: ST Interactive GUI
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 ST Disco L475 IOT01 (B-L475E-IOT01A)
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 samples/boards/stm32/bluetooth/interactive_gui in the Zephyr tree.
