WICED Smart Quick Start Guide
Connect the WICED Smart Tag
The USB interface connects the WICED Smart tag to the PC. The USB interface provides a serial-UART
interface for programming and debugging, and can also provide +5V power.
To enable the USB interface of the tag, SW4 should be in the VUSB position and SW5 should be in the VREG
position (see
Figure 1 on page 9
Connect the WICED Smart tag to the development PC with a USB cable; the USB UART driver will load
automatically.
Verify Driver Installation
To verify that driver installation is complete:
1. Open the Device Manager (right-click My Computer and select Properties).
2. In the System Properties window, select Hardware, Device Manager. The two WICED Smart tag USB
serial ports are listed under <PC-NAME>\Ports (COM & LPT) as shown in the screenshot below.
Note: In the screenshot, the Device Manager identifies the WICED Smart tag USB serial COM
ports as COM10 and COM9. The assigned port numbers vary among systems. The first port
(HCI UART) is used to download the application to the WICED Smart Tag; the second can be used
to communicate with the chip over the peripheral UART.
Note: Check the COM port assignments each time the Smart Tag is unplugged and then reconnected,
because the assigned COM port numbers may change in that situation.
If an error occurs during driver installation, download new drivers from Windows Update. Verify you
have an Internet connection and wait for the drivers to automatically install. If the WICED Smart tag
does not appear in the Device Manager after reinstalling drivers via Windows Update, then the drivers
can be manually installed from the Drivers folder of the SDK installation. If the error persists, then
check all switch settings (see
cable.
