WiFi NORA Click

WiFi NORA Click is a compact add-on board that provides WiFi and BLE connectivity for professional-grade applications. This board features the NORA-W366-00B6-00B, a dual-band WiFi module with Bluetooth Low Energy (BLE) from u-blox, offering support for WiFi 4 (802.11a/b/g/n) in both 2.4 and 5GHz bands and Bluetooth v5.3 with peripheral and central roles. It features a UART interface for easy integration with the host MCU, high-level AT command configuration, and robust security protocols, including WPA2/WPA3 and TLS encryption. The board also includes a user-configurable RGB LED indicator and buttons for bootloader and application mode selection.

Click library

• Author : Stefan Ilic
• Date : Jan 2024.
• Type : UART type

Software Support

We provide a library for the WiFi NORA 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 WiFi NORA Click driver.

Standard key functions :

• wifinora_cfg_setup Config Object Initialization function.

  void wifinora_cfg_setup ( wifinora_cfg_t *cfg );

• wifinora_init Initialization function.

  err_t wifinora_init ( wifinora_t *ctx, wifinora_cfg_t *cfg );

Example key functions :

• wifinora_hw_reset This function is used to perform HW reset.

  void wifinora_hw_reset ( wifinora_t *ctx );

• wifinora_send_cmd This function is used to send a desired command.

  void wifinora_send_cmd ( wifinora_t *ctx, uint8_t *at_cmd_buf );

• wifinora_send_cmd_with_par This function sends a desired command with the parameter.

  void wifinora_send_cmd_with_par ( wifinora_t *ctx, uint8_t *at_cmd_buf, uint8_t *param_buf );

Example Description

This example demonstrates the use of WiFi NORA 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, tests the communication, and after that restarts the device, and performs example configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    wifinora_cfg_t wifinora_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.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    wifinora_cfg_setup( &wifinora_cfg );
    WIFINORA_MAP_MIKROBUS( wifinora_cfg, MIKROBUS_1 );
    if ( UART_ERROR == wifinora_init( &wifinora, &wifinora_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    wifinora_process( );
    wifinora_clear_app_buf( );

    // Hardware reset
    wifinora_hw_reset( &wifinora );
    error_flag = wifinora_rsp_check( WIFINORA_RSP_READY );
    wifinora_error_check( error_flag );

    // Communication check
    wifinora_send_cmd( &wifinora, WIFINORA_CMD_AT );
    error_flag = wifinora_rsp_check( WIFINORA_RSP_OK );
    wifinora_error_check( error_flag );

    // Factory reset
    wifinora_send_cmd( &wifinora, WIFINORA_CMD_AT_USYFR );
    error_flag = wifinora_rsp_check( WIFINORA_RSP_OK );
    wifinora_error_check( error_flag );

    // Software reset
    wifinora_send_cmd( &wifinora, WIFINORA_CMD_AT_SW_RESET );
    error_flag = wifinora_rsp_check( WIFINORA_RSP_READY );
    wifinora_error_check( error_flag );

    wifinora_send_cmd( &wifinora, WIFINORA_CMD_AT_GMM );
    error_flag = wifinora_rsp_check( WIFINORA_RSP_OK );
    wifinora_error_check( error_flag );

    wifinora_configure_for_example( );

    log_info( &logger, " Application Task " );
}

Application Task

It creates a connection to the TCP-UDP echo server, sends a message to it reads it back, displaces it on the UART terminal, and then closes the connection.

void application_task ( void ) 
{
    wifinora_example( );
}

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.WiFiNORA

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.
