2.2 Identify the COM Port Number

When the driver is installed, determine which COM port Windows has assigned to the USB dongle. Right-click on Computer in the Start Menu, and select Properties.

The System Properties window opens; select Device Manager.

A list of all hardware devices appears. Under the Ports (COM & LPT) section, the device TI CC2540 Low-Power RF to USB CDC Serial Port appears. Next to the name should be the port number (COM#).

Note this port number, as it is needed to use BTool.
