AnyNet 3G-EA Click

AnyNet 3G-EA 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.

• Type : UART type

Software Support

Example Description

This example demonstrates the use of AnyNet 3G-EA Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.AnyNet3GEA

Example Key Functions

• anynet3gea_cfg_setup Config Object Initialization function.

void anynet3gea_cfg_setup ( anynet3gea_cfg_t *cfg );

• anynet3gea_init Initialization function.

err_t anynet3gea_init ( anynet3gea_t *ctx, anynet3gea_cfg_t *cfg );

• anynet3gea_send_cmd This function sends a specified command to the Click module.

void anynet3gea_send_cmd ( anynet3gea_t *ctx, uint8_t *cmd );

• anynet3gea_send_cmd_with_par This function sends a command with specified parameter to the Click module.

void anynet3gea_send_cmd_with_par ( anynet3gea_t *ctx, uint8_t *at_cmd_buf, uint8_t *param_buf );

• anynet3gea_send_cmd_check This function checks the command status.

void anynet3gea_send_cmd_check ( anynet3gea_t *ctx, uint8_t *at_cmd_buf );

Application Init

Initializes the driver and sends a few AT commands to test the communication and configure the Click board.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    anynet3gea_cfg_t anynet3gea_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_info( &logger, " Application Task " );
}

Application Task

Reads all the received data and logs them to the USB UART.

void application_task ( void ) 
{
    anynet3gea_process( );
    anynet3gea_log_app_buf( );
    anynet3gea_clear_app_buf( );
}

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.
