USB-UART SERIAL INTERFACE
The RN4677 PICtail board consists of an USB-UART converter enabling flexible interface to the host PC, a PC terminal utility and SmartPhone APPs to drive both classic
SPP and BTLE data connections. The UART port on the RN4677 is exposed through
an MCP2200 USB-UART serial converter for interfacing easily with a host PC.
Connecting the mini-B USB receptacle (P1) on the RN4677 PICtail board to the USB
port on a PC enumerates the RN4677 PICtail board as a Composite Device Class
(CDC) USB device for serial communication. After the MCP2200 enumerates, a dedicated COM port is assigned on the host PC for serial communication with the RN4677
on the RN4677 PICtail board. A PC terminal utility or application opens then the
assigned COM port and connects to the UART port on RN4677 for serial data transfer
or to configure and control RN4677. If the MCP2200 does not enumerate, ensure that
the MCP2200 drivers are downloaded and manually installed from
www.microchip.com/MCP2200.

USING RN4677 PICtail™ BOARD IN PICtail INTERFACE MODE
The PICtail interface is used to access the UART and the GPIOs available on the
RN4677 module. The PICtail interface configures the RN4677 over the UART using an
external PIC® MCU and then sends and receives raw data over the UART. The PICtail
interface is also used to access GPIOs on the RN4677 using a PIC MCU.
Using the PICtail Plus (J2) or PICtail (J1) interface, the board can be plugged into any
standard Microchip development board, such as the Explorer 16 Development Board
(DM240001) or the PIC18 Explorer Board (DM183032), that supports the PICtail Plus
or PICtail connection interface.
The PICtail interface is used to configure the RN4677 by updating Bluetooth parameters on the internal EEPROM, updating the RN4677 firmware on the internal flash, and
entering the RN4677 into application mode. In application mode, pairing procedure is
performed on the RN4677 after establishing a Bluetooth connection for SPP or BLE
data transfer.
Figure 2-36 and Figure 2-37 show the pin mapping for the PICtail Plus 30-pin interface
and the PICtail 28-pin interface.
