LTE IoT 15 Click
LTE IoT 15 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.

Application Init
Initializes the driver and logger.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, ">>> APP STATE - POWER UP <<<\r\n\n" );
}
#define LTEIOT15_MAP_MIKROBUS(cfg, mikrobus)
MikroBUS pin mapping.

@ LTEIOT15_POWER_UP
Definition main.c:93
Application Task
Application task is split in few stages:
- LTEIOT15_POWER_UP:
Powers up the device, performs a device factory reset and reads system information.
- LTEIOT15_CONFIG_CONNECTION:
Sets configuration to device to be able to connect to the network.
- LTEIOT15_CHECK_CONNECTION:
Waits for the network registration indicated via CEREG command and then checks the signal quality report.
- LTEIOT15_CONFIG_EXAMPLE:
Configures device for the selected example.
- LTEIOT15_EXAMPLE:
Depending on the selected demo example, it sends an SMS message (in PDU or TXT mode) or TCP/UDP message. By default, the TCP/UDP example is selected.
{
switch ( app_state )
{
{
{
log_printf( &logger, ">>> APP STATE - CONFIG CONNECTION <<<\r\n\n" );
}
break;
}
{
if (
LTEIOT15_OK == lteiot15_config_connection( <eiot15 ) )
{
log_printf( &logger, ">>> APP STATE - CHECK CONNECTION <<<\r\n\n" );
}
break;
}
{
if (
LTEIOT15_OK == lteiot15_check_connection( <eiot15 ) )
{
log_printf( &logger, ">>> APP STATE - CONFIG EXAMPLE <<<\r\n\n" );
}
break;
}
{
if (
LTEIOT15_OK == lteiot15_config_example( <eiot15 ) )
{
log_printf( &logger, ">>> APP STATE - EXAMPLE <<<\r\n\n" );
}
break;
}
{
lteiot15_example( <eiot15 );
break;
}
default:
{
log_error( &logger, " APP STATE." );
break;
}
}
}

Note
In order for the examples to work, user needs to set the APN and SMSC (SMS PDU mode only) of entered SIM card as well as the phone number (SMS mode only) to which he wants to send an SMS. Enter valid values for the following macros: SIM_APN, SIM_SMSC and PHONE_NUMBER.
Example:
- SIM_APN "internet"
- SIM_SMSC "+381610401"
- PHONE_NUMBER "+381659999999"
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.
