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 a personal computer or laptop. The Proteus-III Plug allows quick set-up of a radio link between PC  and any system with an integrated Proteus-III radio module.

Ordering information

Functional description

The Proteus-III Plug consists of a Proteus-III radio module along with a 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 a reset. The figure ✶ illustrates all the functional components of the Proteus-III Plug.

Typical Setup
The Proteus-III Plug offers a Command API or a Transparent (“Peripheral Only” mode) on its 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 perform the steps to connect to other Proteus Bluetooth® LE devices, which are connectable.
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.

connect to other Proteus Bluetooth® LE devices, which are connectible. The Mirth 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 APIs for Bluetooth® LE to any App on the Smartphone. This App needs to implement Proteus-Ill I Profiles and Characteristics (UUIDs) as well as the protocol used by Proteus-Ill.

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 a peripheral device that offers its 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.

Taking into operation

To use the Proteus-III Plug, the drivers of the FTDI converter IC has to be installed. This can be achieved by following the FTDI “Install Guides” available at the link below. The  VCP driver for Windows OS will also install D2XX drivers in parallel. In the case of modern Linux Kernels, the VCP driver is already part of the Kernel: Windows VCP: https://www.ftdichip.com/Drivers/VCP.htm

It is recommended to restart the PC after the installation of drivers.

Please note that the FTDI drivers are not available for all platforms. We have tested Windows 10 x64 as well as Raspberry Pi 3B and 4B with Raspbian Buster.

On proper installation of the drivers, the module appears as a virtual COM port on the PC (ttyUSBx on Linux, COMx on Windows) in case of the VCP driver use. This COM  port can be opened in any serial emulator program or user- written software to communicate with the radio module.
The radio module responds to commands in a specific format. Please refer to the corresponding Proteus-III user manual for the complete description of the command set.

When connecting the plug to the PC, it is recommended to reset the plug once.
This can be done using the plug’s reset button or using the CBUS0 pin (see chapter 2. 2. 2. 1). This reset procedure is also recommended after each reboot of the PC.

Timing parameters – Reset and power-up
After resetting the Proteus-Ill Plug a CMD_GETSTATE_CNF is sent (when in Command Mode) to the serial interface as soon as the Proteus-Ill is ready for operation. In Peripheral Only mode this information is not available as a UART signal or on the USB interface.

The USB dongle has a delay -r implemented in the reset line towards the module to ensure stable VCC and stable FT231x signal levels after plugging the dongle into the USB of the host. This will introduce an additional typ. delay of -c = 50ms in case of a Proteus-Ill Plug power-up and reset. The Reset function of the Proteus-Ill Plug (via push-button, CBUSO or CMD_RESET_REQ) has also this additional delay.

Usage of CBUS pins
To switch the CBUS pins static HIGH or LOW and thus to use the provided pins functions of the Proteus-III radio module, the D2XX driver of FTDI has to be used. This driver is part of the previously mentioned VCP driver installation in the case of Windows OS. In the case of Linux, a manual installation is required.
Please follow FTDI’s “Installation Guides” for proper D2XX install: https://www.ftdichip.com/Drivers/D2XX.htm

Examples codes and Tutorials for ¨how to use the D2XX driver within your own software tool¨ can be found in the software example section of:
https://www.ftdichip.com/Support/SoftwareExamples/CodeExamples.htm

Resetting the Proteus-Ill Plug using the CBUS pin The /RESET pin of the Proteus-Ill can be used to reset the integrated radio module. As the /RESET pin is connected to the CBUSO pin of the integrated FTDI chip, the radio module can be reset by pulling the CBUSO pin low for at least 100ms and releasing it to a high level again. By default, the CBUSO pin of the FT231X is configured as FT_CBUS_GPIO (bit-bang), such that the FTDI D2XX driver function SetBitMode can be used.

/ set CBUSO to output level LOW // prep: create and connect an FTDI device intance /

SetBitMode(0x10, FTDI.FT_BIT_MODES.FT_BIT_MODE_CBUS_BITBANG);

/ hold CBUSO for at least 100ms on LOW level / wait_ms(100);

/* clear FTDI receive and send buffers d Purge(FTDI.FT_PURGE.FT_PURGE_RX I FTDI.FT_PURGE.FT_PURGE_TX);

/ set CBUSO to output level HIGH /

SetBitMode(0x00, FTDI.FT_BIT_MODES.FT_BIT_MODE_RESET);

/ a delay according to the reset timing parameter will occur (see manual) /

/ disconnect and close the FTDI device instance /

Code 1:Pin reset via CBUS0 using the D2XX driver

Switching from command mode to peripheral only mode and vice versa
The operation mode of the Proteus-III Plug can be defined by applying the right voltage level at the OP_MODE pin of the Proteus-III during its start-up phase. As this pin is connected to the CBUS3 pin of the built-in FTDI converter chip, the CBUS3 pin can be controlled by the host.

Additional care has to be taken when configuring the pins on the FTDI converter.
The EEPROM content of the chip is changed by this action. Any misconfiguration may prevent the normal operation of the USB dongle. This method is not intended for periodic use. The factory defaults of the CBUS pins are: CBUS0 to CBUS2 – GPIO, CBUS3 – CBUS_Drive_0

By default, the CBUS3 pin of the FT231 X is configured as FT_CBUS_Drive_O (static LOW) such that the Proteus-Ill Plug starts in command mode. To start the plugin peripheral only mode, configure the CBUS3 pin as FT_CBUS_Drive_1 (static HIGH) and perform a reset of the device, as specified in chapter 2.2.2.1.
In case the plug shall start in command mode again, configure the CBUS3 pin as FT_CBUS_Drive_O (static LOW) and perform a reset of the device, as specified in chapter 2.2.2.1.

For reasons of simplicity, Würth Elektronik eiSos provides a small Windows PC tool¹, that uses the FTDI D2XX driver instructions to set the Proteus-III Plug into the desired operation mode.
