WIZFI360 Click

WIZFI360 Click is a compact add-on board for reliable WiFi connectivity in industrial applications. This board features the WIZFI360, a WiFi module from WIZnet, known for its low power consumption and full compliance with IEEE802.11 b/g/n standards. The board supports SoftAP, Station, and SoftAP+Station modes, operates within the frequency range of 2400MHz to 2483.5MHz, and offers a versatile serial port baud rate of up to 2Mbps. It features WPA_PSK and WPA2_PSK encryption for secure communication, configurable operating channels from 1 to 13, and the ability to handle up to 5 simultaneous TCP/UDP links.

Software Support

We provide a library for the WIZFI360 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

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

Library Description

This library contains API for WIZFI360 Click driver.

Standard key functions :

• wizfi360_cfg_setup Config Object Initialization function.

  void wizfi360_cfg_setup ( wizfi360_cfg_t *cfg );

• wizfi360_init Initialization function.

  err_t wizfi360_init ( wizfi360_t *ctx, wizfi360_cfg_t *cfg );

Example key functions :

• wizfi360_write_command This function writes a desired command by using the UART serial interface.

  err_t wizfi360_write_command ( wizfi360_t *ctx, uint8_t *command )

• wizfi360_write_cmd_param This function writes a desired command, prefix and parameter by using UART serial interface.

  err_t wizfi360_write_cmd_param ( wizfi360_t *ctx, uint8_t *command, uint8_t *prefix, uint8_t *param );

• wizfi360_send_message This function sends messages to the host in normal transmission mode using the UART serial interface.

  err_t wizfi360_send_message ( wizfi360_t *ctx, uint8_t *message );

Example Description

This example demonstrates the use of the WIZFI360 Click board by processing the incoming data and displaying them on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver, connects to the desired WiFi network, and then connects to the TCP/UDP server and configures SNTP parameter.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    wizfi360_cfg_t wizfi360_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.

Application Task

The demo app displays current time data, sends data messages to the TCP/UDP server, reads and processes all incoming data and displays them on the USB UART.

Note

In order for the examples to work without using Planet Debug, the user needs to set the SSID and password of the target AP.

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.WIZFI360

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
