AnyNet 3G-AA click

AnyNet 3G-AA click is a cellular to AWS gateway device, which provides developers with the complete solution for various IoT applications, by using the AWS IoT and Cloud Storage services for the data storage, analyzing and processing. AnyNet click boardâ„¢ provides a secure connection with the AWS over the air (OTA), by utilizing the Quectel UG95-AA 3G module, offering UMTS/HSPA coverage for the North American region, Eseye ES4623 embedded SIM card, that can work with all the major cellular operators within the NA region. The AnyNet 3G click can be used as an AWS IoT button with almost no configuration.

Click library

• Author : Stefan Filipovic
• Date : May 2023.
• Type : UART type

Software Support

We provide a library for the ANYNET3GAA 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 LibStockâ„¢ or found on Mikroe github account.

Library Description

This library contains API for ANYNET3GAA Click driver.

Standard key functions :

• anynet3gaa_cfg_setup Config Object Initialization function.

  void anynet3gaa_cfg_setup ( anynet3gaa_cfg_t *cfg );

• anynet3gaa_init Initialization function.

  err_t anynet3gaa_init ( anynet3gaa_t *ctx, anynet3gaa_cfg_t *cfg );

Example key functions :

• anynet3gaa_send_cmd This function sends a specified command to the click module.

  void anynet3gaa_send_cmd ( anynet3gaa_t *ctx, uint8_t *cmd );

• anynet3gaa_send_cmd_with_par This function sends a command with specified parameter to the click module.

  void anynet3gaa_send_cmd_with_par ( anynet3gaa_t *ctx, uint8_t *at_cmd_buf, uint8_t *param_buf );

• anynet3gaa_send_cmd_check This function checks the command status.

  void anynet3gaa_send_cmd_check ( anynet3gaa_t *ctx, uint8_t *at_cmd_buf );

Example Description

This example demonstrates the use of AnyNet 3G-AA click board.

The demo application is composed of two sections :

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. */
    anynet3gaa_cfg_t anynet3gaa_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.
    anynet3gaa_cfg_setup( &anynet3gaa_cfg );
    ANYNET3GAA_MAP_MIKROBUS( anynet3gaa_cfg, MIKROBUS_1 );
    if ( UART_ERROR == anynet3gaa_init( &anynet3gaa, &anynet3gaa_cfg ) )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }

    anynet3gaa_process( );
    anynet3gaa_clear_app_buf( );

    // Check communication
    anynet3gaa_send_cmd( &anynet3gaa, ANYNET3GAA_CMD_AT );
    error_flag = anynet3gaa_rsp_check( ANYNET3GAA_RSP_OK );
    anynet3gaa_error_check( error_flag );

    // Query VERSION info for the AnyNet AWS IoT code
    anynet3gaa_send_cmd( &anynet3gaa, ANYNET3GAA_CMD_AWSVER );
    error_flag = anynet3gaa_rsp_check( ANYNET3GAA_RSP_OK );
    anynet3gaa_error_check( error_flag );

    // Query IMEI of the modem on the board
    anynet3gaa_send_cmd( &anynet3gaa, ANYNET3GAA_CMD_GSN );
    error_flag = anynet3gaa_rsp_check( ANYNET3GAA_RSP_OK );
    anynet3gaa_error_check( error_flag );

    // Query ICCID of the SIM
    anynet3gaa_send_cmd( &anynet3gaa, ANYNET3GAA_CMD_QCCID );
    error_flag = anynet3gaa_rsp_check( ANYNET3GAA_RSP_OK );
    anynet3gaa_error_check( error_flag );

    // Check AWS State
    anynet3gaa_send_cmd_check( &anynet3gaa, ANYNET3GAA_CMD_AWSSTATE );
    error_flag = anynet3gaa_rsp_check( ANYNET3GAA_RSP_OK );
    anynet3gaa_error_check( error_flag );

    // Open AWS topic
    #define AWS_TOPIC_OPEN "0,\"MY_TOPIC_OPEN\""
    anynet3gaa_send_cmd_with_par( &anynet3gaa, ANYNET3GAA_CMD_AWSPUBOPEN, AWS_TOPIC_OPEN );
    error_flag = anynet3gaa_rsp_check( ANYNET3GAA_RSP_OK );
    anynet3gaa_error_check( error_flag );

    // Subscribe to AWS topic
    #define AWS_TOPIC_SUBSCRIBE "0,\"MY_TOPIC_SUBSCRIBE\""
    anynet3gaa_send_cmd_with_par( &anynet3gaa, ANYNET3GAA_CMD_AWSSUBOPEN, AWS_TOPIC_SUBSCRIBE );
    error_flag = anynet3gaa_rsp_check( ANYNET3GAA_RSP_OK );
    anynet3gaa_error_check( error_flag );
    anynet3gaa_clear_app_buf( );

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

Application Task

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

void application_task ( void ) 
{
    anynet3gaa_process( );
    anynet3gaa_log_app_buf( );
    anynet3gaa_clear_app_buf( );
}

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

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.AnyNet3GAA

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.
