WiFi 11 Click

WiFi 11 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.

Example Description

This example reads and processes data from WiFi 11 Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Wifi11

Example Key Functions

• wifi11_cfg_setup Config Object Initialization function.

void wifi11_cfg_setup ( wifi11_cfg_t *cfg );

• wifi11_init Initialization function.

err_t wifi11_init ( wifi11_t *ctx, wifi11_cfg_t *cfg );

void wifi11_connect_to_ap ( wifi11_t *ctx, char *ssid, char *password );

Application Init

Initializes the driver and powers up the module, then connects to the desired AP and creates TCP and UDP servers on the desired local port.

void application_init ( void )
{
    log_cfg_t log_cfg;
    wifi11_cfg_t cfg;

     * 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_printf( &logger, "\r\n ---- Please connect to the TCP/UDP server listed above via" );
    log_printf( &logger, " a TCP/UDP client ---- \r\n" ); 
}

Application Task

Logs all the received data and module's responses on the USB UART.

void application_task ( void )
{
    wifi11_process( );
    wifi11_log_app_buf( );
}

Note

In order for the example to work, user needs to set the AP SSID, password, and Local port on which the TCP and UDP servers will be created. Enter valid data for the following macros: AP_SSID, AP_PASSWORD and LOCAL_PORT.

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.
