1 Introduction
The Proteus-III is a radio module that provides wireless connectivity capabilities in the
2.4 GHz frequency band. The Proteus-III Plug incorporates the Proteus-III in a USB stick
form factor enabling easy interfacing with any USB enabled device like personal computer or
laptop. The Proteus-III Plug allows quick set-up of a radio link between PC and any system
with integrated Proteus-III radio module.

2 Functional description
The Proteus-III Plug consists of Proteus-III radio module along with an serial-to-USB adapter
that enables direct connection to any USB compatible device. An FTDI serial-to-USB converter chip FT231X connects the USB interface of the Proteus-III Plug to the UART pins of
the integrated radio module. Besides UART, additional digital GPIO pins (CBUS) are connected to the radio module to provide special functions like reset. Figure1illustrates all the
functional components of Proteus-III Plug.

2.1 Typical Setup
The Proteus-III Plug offers a Command API or a Transparent ("Peripheral Only" mode) on
it’s UART interface.
The Proteus-III Plug does not integrate into the possibly existing Bluetooth
interface of any host like a Windows or Linux PC.
In the first setup shown below the PC does not need to implement any Bluetooth®specific
functions or drivers, just the Command API of the Proteus-III needs to be implemented using
a SerialPort connection (via VCP or D2XX).
This API allows to select the Central Role, Scan for devices and performing the steps to
connect to other Proteus Bluetooth®LE devices, which are connectible.
The Würth Elektronik eiSos Wireless Connectivity SDK includes an example implementation
as C source code which can be ported with minimum effort to any host.
®
In the second typical setup the Smartphone includes a Bluetooth®LE Chipset and Bluetooth®LE
Stack (as part of the Smartphone operating system) offering API’s for Bluetooth®LE to any
App on the Smartphone. This App needs to implement Proteus-III Profiles and Characteristics (UUIDs) as well as the protocol used by Proteus-III.

The Proteus-III Application Note "Advanced User Guide" (see: WE Documentation Download Page) provides all information required for developers.
The Proteus-III Plug in this setup is being used as peripheral device that offers it’s services.
This Peripheral Mode can be used either in Command Mode or in the so called "Peripheral
Only Mode", which offers a transparent UART to Bluetooth®LE (and vice versa) interface
once a central device initiated a connection and the connection setup negotiation between
the two roles was successful.
