Thyone-I Click

How does it work?

Thyone-I Click is based on the WIRL-PRO2 Thyone-I (2611011021000) module from Würth Elektronik. This radio sub-module provides wireless communication for various devices, including control systems, remote controls, and sensor nodes. Operating within the globally available 2.4GHz license-free band, the Thyone-I ensures secure and reliable data transmission in both point-to-point and mesh configurations. Pre-loaded with Würth Elektronik’s WE-ProWare radio stack, it offers high flexibility and reliability. The module interfaces with the host system via a serial UART interface, simplifying the configuration and control of the radio through an easy command interface. Additionally, it features a transparent mode for cable replacement applications, functioning as a serial-to-radio adapter.

The Thyone-I module carries versatile features, from low-power, long-range capabilities to line-powered, high-throughput performance, making it energy-efficient. Users can choose between the onboard PCB antenna for compact designs or an external antenna for long-range applications, thanks to the onboard ANT u.Fl connector. The module supports a radio profile with a 2Mbit/s data transmission rate, leading to an effective end-to-end throughput of approximately 400kbit/s. It also offers embedded security with a secure bootloader and hardware-accelerated end-to-end encryption. Other features include repeater functionality for simple flooding mesh network creation.

Pre-flashed, tested, and ready to use out-of-the-box, the Thyone-I module complies with various regulatory requirements, making it suitable for global use. Operating in the 2.4GHz band, it can be configured to use one of the 39 channels from 2403MHz to 2479MHz. The module’s transmit power ranges from -40dBm to +8dBm, affecting both radio range and current consumption. When powered on, the Thyone-I can be put in Command or Transparent modes of operations via the MODE switch (clearly marked on the board T for Transparent and C for Command). Command mode is the standard mode of operation for Thyone-I. The module can be configured and controlled in this mode using the command interface. In the transparent mode, the module acts as a transparent UART-radio bridge, and any data received on the UART interface will be sent via radio.

As mentioned, communication between the Thyone-I module and the host MCU is established through a UART interface, standard UART RX and TX pins, and hardware flow control pins (CTS/RTS). The default communication speed is 115200bps, ensuring efficient data exchange. The board also includes a reset (RST) pin for hard resetting the module, a wake-up pin for waking the module from Sleep mode, and a Boot (BT) pin to trigger the bootloader mode for firmware updates when set to a low logic level during reset.

It also features three LED indicators: a yellow BUSY LED indicating data transmission activity in Transparent mode and blue and green LEDs (LD1 for TX and LD2 for RX) for RF transmission status. Additionally, it has GPIO and Debug pins. The GPIO pins (B1 to B6) can be configured and controlled for various digital I/O functions, while the Debug pins utilize the Serial Wire Debug (SWD) interface for debugging purposes.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Thyone-I Click electrical specifications

Software Support

We provide a library for the Thyone-I Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on MIKROE github account.

Library Description

This library contains API for Thyone-I Click driver.

Key functions

• thyonei_get_req This command can be used to set individual setting parameters in flash of Thyone-I Click board™.

• thyonei_multicast_data_req This command provides the multicast data transmission to a group of modules configured with the same MAC GROUP ADDRESS of Thyone-I Click board™.

• thyonei_unicast_data_req This command provides the unicast data transmission to the configured MAC DESTINATION ADDRESS of Thyone-I Click board™.

Example Description

This example demonstrates the use of the Thyone-I Click board™ by sending and receiving data and displaying them on the USB UART.

void application_task ( void ) 
{
#if ( TRANSMITTER_MAC_ADDRESS == SOURCE_ADDRESS )
    uint8_t message_data[ PROCESS_BUFFER_SIZE ] = { 0 };

    #define BROADCAST_MESSAGE       "Broadcast"
    strcpy( message_data, MESSAGE );
    strcat( message_data, BROADCAST_MESSAGE );
    log_printf( &logger, " Thyone-I sending broadcast message: rn" );
    thyonei_broadcast_data_req( &thyonei, strlen( message_data ), message_data );
    thyonei_get_resp ( &thyonei, THYONEI_CMD_DATA_CNF );
    Delay_ms( 5000 );

    #define MULTICAST_MESSAGE       "Multicast"
    strcpy( message_data, MESSAGE );
    strcat( message_data, MULTICAST_MESSAGE );
    log_printf( &logger, " Thyone-I sending multicast message: rn" );
    thyonei_multicast_data_req( &thyonei, strlen( message_data ), message_data );
    thyonei_get_resp ( &thyonei, THYONEI_CMD_DATA_CNF );

    #define UNICAST_MESSAGE         "Unicast"
    strcpy( message_data, MESSAGE );
    strcat( message_data, UNICAST_MESSAGE );
    log_printf( &logger, " Thyone-I sending unicast message: rn" );
    thyonei_unicast_data_req( &thyonei, strlen( message_data ), message_data );
    thyonei_get_resp ( &thyonei, THYONEI_CMD_DATA_CNF );
