When the EVB board is connected to a USB port on a host PC, the system will enumerate two serial ports: one for HCI
UART and one for PUART. The HCI UART port is used for programing from ModusToolbox. Use a serial port terminal
application to open the PUART port so that the firmware debug output can be shown. Use 115200 Baud, 8 bits, no parity.
Use ‘LF’ as the ‘return’ character for both TX and RX lines.
The wiring can be arranged as shown:
With this arrangement, after programming, the device can be detached easily and used as a stand-alone device.
