WiFi NORA Click

WiFi NORA Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

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

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.WiFiNORA

Example 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 );
  • 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 );

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( );
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
