Why CYW920719 board will get 4 interfaces when attached to linux machine

[soG_4608441]

When we will connect CYW920719 board to linux machine we will get 4 interfaces like

ttyUSB1

ttyUSB2

ttyWICED_HCI_UART1

ttyWICED_PUART2

What is the use of 4 interfaces? Why they provided 4 interfaces?.

20179 has two UART ports, namely HCI_UART and Peripheral UART (or pUART). The EVK board has a FTDI chip to enable USB to UART conversion so as to allow communication and programming. That's why you will see two UART ports. Do refer to the EVK user guide in the Doc folder within the SDK for more HW details.
