It is mainly used for production testing of Dialog Bluetooth products. Looking at the schematic design, the USB is converted to a 16-channel serial port through 4 pieces of FT4232, and then the USB of these 4 pieces of FT4232 is connected to the USB HUB chip USB2512. The software part of this tool (including the host computer) is not open source, but the schematic diagram and PCB related files are.
