LTE IoT 4 Click is a compact add-on board that contains an IoT module with worldwide coverage. This board features the nRF9160, highly integrated, low-power SiP with LTE-M/NB-IoT and GPS from Nordic Semiconductor.
We provide a library for the LTEIoT4 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.
This library contains API for LTEIoT4 Click driver.
Config Object Initialization function.
void lteiot4_cfg_setup ( lteiot4_cfg_t *cfg );
Initialization function.
LTEIOT4_RETVAL lteiot4_init ( lteiot4_t *ctx, lteiot4_cfg_t *cfg );
Click Default Configuration function.
void lteiot4_default_cfg ( lteiot4_t *ctx );
Sets state of the rst pin setting.
void lteiot4_set_rst ( lteiot4_t *ctx, uint8_t state );
Send command function.
void lteiot4_send_cmd ( lteiot4_t *ctx, char *cmd );
Set sim card APN.
void lteiot4_set_sim_apn ( lteiot4_t *ctx, char *sim_apn );
This example reads and processes data from LTE IoT 4 clicks.
The demo application is composed of two sections :
Initializes driver and wake-up module.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
lteiot4_cfg_t lteiot4_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.

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.
