9. Kit Features
The kit contains a board controller that is responsible for performing various board-level tasks, such as handling the debugger and the
Advanced Energy Monitor. An interface is provided between the BGM113 and the board controller in the form of a UART connection.
The connection is enabled by setting the VCOM_ENABLE (tied high) line high, and using the lines VCOM_TX (PA0) and VCOM_RX
(PA1) for communication.
Note:
The board controller is only available when USB power is connected.
9.1 Virtual COM Port
When enabling virtual serial communication (VCOM), the board controller makes communication possible on the following interfaces:
• Virtual USB COM port using a CDC driver.
• TCP/IP, by connecting to the Wireless STK on port 4901 with a telnet client.
The VCOM functionality can operate in two different modes:
• Transparent mode allows the target to communicate using a regular serial driver. The board controller forwards the raw byte stream
to its interfaces.
• BSP-mode is initiated by a BSP call in the target application. This mode enables the target to use all BSP functionality, while having
access to VCOM over USB and Ethernet.
