LTE IoT 14 Click is a compact add-on board designed for low-latency and low-throughput wireless data communication in IoT applications. This board features the SIM7090G, a multi-band LTE module from SIMCom, supporting Cat-M and Cat-NB communication modes and multi-constellation GNSS (GPS/GLONASS/Galileo/BeiDou) for global connectivity. This board features a UART interface for communication with the host MCU, a USB Type-C port for data transfer and firmware upgrades, as well as visual indicators for real-time network and power status. It also includes test points for easier debugging, dual SMA connectors for LTE and GNSS antennas, and a micro SIM card holder for flexible service provider selection.
We provide a library for the LTE IoT 14 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 LTE IoT 14 Click driver.
lteiot14_cfg_setup
Config Object Initialization function. lteiot14_init
Initialization function. lteiot14_set_sim_apn
This function sets APN for sim card. lteiot14_send_sms_text
This function sends text message to a phone number. lteiot14_send_cmd
This function sends a specified command to the Click module. Application example shows device capability of connecting to the network and
sending SMS or TCP/UDP messages, or retrieving data from GNSS using standard "AT" commands.
The demo application is composed of two sections :
Initializes the driver and logger.
Application task is split in few stages:
Powers up the device, performs a device reset and reads system information.
Sets configuration to device to be able to connect to the network (used only for SMS or TCP/UDP demo examples).
Waits for the network registration indicated via CREG command and then checks the signal quality report (used only for SMS or TCP/UDP demo examples).
Configures device for the selected example.
Depending on the selected demo example, it sends an SMS message (in PDU or TXT mode) or TCP/UDP message or waits for the GPS fix to retrieve location info from GNSS. By default, the TCP/UDP example is selected.
In order for the examples to work (except GNSS example), 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_TO_MESSAGE.
Example:
- SIM_APN "internet"
- SIM_SMSC "+381610401"
- PHONE_NUMBER_TO_MESSAGE "+381659999999"
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.

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.
