The SPI does not require users to choose a specific COM port. Simply select the CC31xx SPI option in the tool to start the connection. However, with SPI connection, only one CC31xx can be connected to a PC at a time. This is because Radio Tool cannot determine which CC31xx device to connect to if multiple CC31xx devices are present. For large volume testing, TI recommends using the CC31xx UART.
