  2. Power off the target board and power on again.

  3. Connect a USB weight scale device to the board.

this example could be tested with the “usb_device_phdc_manager” example in pairs.

Run the example

  1. Connect the board UART to the PC and open the COM port in a terminal tool.

  2. Plug in a hub or the USB weight scale device to the board that is running the PHDC manager example. The attached information prints out in the terminal.

  3. The weight scale data (body mass and body mass index) is automatically sent to the host. The scan report number, time, value, and unit of each field is shown in terminal tool.

The following figure is an example for attaching one USB weight scale device.
