AnyNet 3G-EA click

‍AnyNet 3G-EA 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 board™ provides a secure connection with the AWS over the air (OTA), by utilizing the Quectel UG95-EA 3G module, offering worldwide UMTS/HSPA and GSM/GPRS/EDGE coverage Eseye ES4623 embedded SIM card, that can work with more than 235 cellular operators from all over the world. An Eseye embedded sim card can work with more than 235 cellular operators from all over the world. 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 ANYNET3GEA 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 ANYNET3GEA Click driver.

Standard 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 );

Example key functions :

• 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 );

Example Description

‍This example demonstrates the use of AnyNet 3G-EA 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;  
    anynet3gea_cfg_t anynet3gea_cfg;  
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    anynet3gea_cfg_setup( &anynet3gea_cfg );
    ANYNET3GEA_MAP_MIKROBUS( anynet3gea_cfg, MIKROBUS_1 );
    if ( UART_ERROR == anynet3gea_init( &anynet3gea, &anynet3gea_cfg ) )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }
    
    anynet3gea_process( );
    anynet3gea_clear_app_buf( );
 
    // Check communication
    anynet3gea_send_cmd( &anynet3gea, ANYNET3GEA_CMD_AT );
    error_flag = anynet3gea_rsp_check( ANYNET3GEA_RSP_OK );
    anynet3gea_error_check( error_flag );
    
    // Query VERSION info for the AnyNet AWS IoT code
    anynet3gea_send_cmd( &anynet3gea, ANYNET3GEA_CMD_AWSVER );
    error_flag = anynet3gea_rsp_check( ANYNET3GEA_RSP_OK );
    anynet3gea_error_check( error_flag );
    
    // Query IMEI of the modem on the board
    anynet3gea_send_cmd( &anynet3gea, ANYNET3GEA_CMD_GSN );
    error_flag = anynet3gea_rsp_check( ANYNET3GEA_RSP_OK );
    anynet3gea_error_check( error_flag );
    
    // Query ICCID of the SIM
    anynet3gea_send_cmd( &anynet3gea, ANYNET3GEA_CMD_QCCID );
    error_flag = anynet3gea_rsp_check( ANYNET3GEA_RSP_OK );
    anynet3gea_error_check( error_flag );
    
    // Check AWS State
    anynet3gea_send_cmd_check( &anynet3gea, ANYNET3GEA_CMD_AWSSTATE );
    error_flag = anynet3gea_rsp_check( ANYNET3GEA_RSP_OK );
    anynet3gea_error_check( error_flag );
    
    // Open AWS topic
    #define AWS_TOPIC_OPEN "0,\"MY_TOPIC_OPEN\""
    anynet3gea_send_cmd_with_par( &anynet3gea, ANYNET3GEA_CMD_AWSPUBOPEN, AWS_TOPIC_OPEN );
    error_flag = anynet3gea_rsp_check( ANYNET3GEA_RSP_OK );
    anynet3gea_error_check( error_flag );
    
    // Subscribe to AWS topic
    #define AWS_TOPIC_SUBSCRIBE "0,\"MY_TOPIC_SUBSCRIBE\""
    anynet3gea_send_cmd_with_par( &anynet3gea, ANYNET3GEA_CMD_AWSSUBOPEN, AWS_TOPIC_SUBSCRIBE );
    error_flag = anynet3gea_rsp_check( ANYNET3GEA_RSP_OK );
    anynet3gea_error_check( error_flag );
    anynet3gea_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 ) 
{
    anynet3gea_process( );
    anynet3gea_log_app_buf( );
    anynet3gea_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 LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

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

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.
