NB IoT 2 Click is a compact add-on board that contains a compact LTE Cat NB2 module with ultra-low power consumption. This board features the BC66-NA, a high-performance, multi-band LTE Cat NB2 module with extremely low power consumption from Quectel Wireless Solutions.
We provide a library for the NB IoT 2 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 NB IoT 2 Click driver.
nbiot2_cfg_setup
Config Object Initialization function.
void nbiot2_cfg_setup ( nbiot2_cfg_t *cfg );
nbiot2_init
Initialization function.
err_t nbiot2_init ( nbiot2_t *ctx, nbiot2_cfg_t *cfg );
nbiot2_set_rst_pin_state
This function sets RST pin state.
void nbiot2_set_rst_pin_state ( nbiot2_t *ctx, uint8_t state );
nbiot2_hw_reset
NB IoT 2 hardware reset function.
void nbiot2_hw_reset ( nbiot2_t *ctx );
nbiot2_send_cmd
NB IoT 2 send command function.
void nbiot2_send_cmd ( nbiot2_t *ctx, char *cmd );
This example reads and processes data from NB IoT 2 clicks.
The demo application is composed of two sections :
Initializes driver, wake-up module and sets default configuration for connecting device to network.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
nbiot2_cfg_t nbiot2_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.

- TCP/UDP example - connecting to echo server and writing and reading data.
- SMS example - Sending SMS message to desired number using TEXT or PDU mode.

}
}
}
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 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.
