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

2 Functional description
The Thyone-I USB radio stick consists of Thyone-I 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 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. Figure 1 illustrates all the functional components of
Thyone-I USB radio stick.
Figure 1: Block diagram of the Thyone-I USB radio stick
For detailed function description of the Thyone-I USB radio stick, please refer
to the user manual of the underlying radio module Thyone-I [2].
2.1 Typical Setup
The Thyone-I USB radio stick offers either a Command API (default) or a Transparent Mode on
it’s UART interface.
Two modules or USB dongles can communicate with each other if they share the same radio
configuration (radio profile and channel). Based on the network configuration, data can be
broadcast, multicast to a group or unicast to a specific module. The default module settings
are selected in such a way that an plug and play experience is possible by using 2 dongles and
the PC tool smart commander [1].

2.2 Taking into operation
The serial-to-USB FTDI converter chip FT231X requires special drivers to be installed for
proper operation. The Virtual COM Port (VCP) drivers have to be installed by following the
"Installation Guides" found under: https://www.ftdichip.com/Drivers/VCP.htm
It is recommended to restart the PC after installation of drivers.
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 correspond-
ing Thyone-I user manual [2] for the complete description of the command set.
When connecting the USB radio stick to the PC, it is recommended to reset
the USB radio stick once. This can be done using the USB radio stick’s reset
button or using the CBUS0 pin (see chapter 2.2.1.1 ). This reset procedure is
also recommended after each reboot of the PC.

2.2.1 Usage of CBUS pins
To switch the CBUS pins static HIGH or LOW and thus to use the provided pins functions of
the Thyone-I radio module, the D2XX driver of FTDI has to be used. This driver is part of the
previous mentioned VCP driver installation in case of Windows OS. In 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
2.2.1.1 Resetting the Thyone-I USB radio stick using the CBUS pin
The /RESET pin of the Thyone-I can be used to reset the integrated radio module. As the
/RESET pin is connected to the CBUS0 pin of the integrated FTDI chip, the radio module can
be reset by pulling the CBUS0 pin low for at least 100 ms and releasing it to high level again.
By default, the CBUS0 pin of the FT231X is configured as FT_CBUS_GPIO (bit bang), such that
the FTDI D2XX driver function SetBitMode can be used.
/*prep: create and connect an FTDI device intance */
/*set CBUS0 to output level LOW */
SetBitMode(0x10, FTDI.FT_BIT_MODES.FT_BIT_MODE_CBUS_BITBANG);
/*hold CBUS0 for at least 100ms on LOW level */
wait_ms(100);
/*clear FTDI receive and send buffers */
Purge(FTDI.FT_PURGE.FT_PURGE_RX | FTDI.FT_PURGE.FT_PURGE_TX);
/*set CBUS0 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
2.2.1.2 Switching from command mode to transparent mode and vice versa
The operation mode of the Thyone-I USB radio stick can be defined by applying the right voltage
level at the OP_MODE pin of the Thyone-I 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 con-
verter. The EEPROM content of the chip is changed by this action. Any miscon-
figuration 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 FT231X is configured as FT_CBUS_Drive_0 (static LOW) such
that the Thyone-I USB radio stick starts in command mode. To start the USB radio stick in
transparent mode, configure the CBUS3 pin as FT_CBUS_Drive_1 (static HIGH) and perform a
reset of the device, as specified in chapter 2.2.1.1 .
In case the USB radio stick shall start in command mode again, configure the CBUS3 pin
as FT_CBUS_Drive_0 (static LOW) and perform a reset of the device, as specified in chap-
ter 2.2.1.1 .
