# Title: Nano LR Click Board™ ## Description: How Does The Nano LR Click Board™ Nano LR Click Board™ Work? The Nano LR Click Board™, as its foundation uses the EMB-LR1276S, a sub-1GHz wireless module that supports the LoRaWAN long-range wireless protocol based on the SAMR34 SiP from Embit. It offers a long-range spread spectrum communication with high interference immunity. Nano LR Click is ideal for use in various applications, such as IoT, home and building automation, wireless alarm and security systems, automated meter reading, industrial monitoring and control, and more. The EMB-LR1276S can be configured as an embedded microsystem or a simple data modem for low power applications in the 868MHz and 915MHz radio bands. It is equipped with up to 256 KB of Flash and up to 40 KB of SRAM and it supports long-range and FSK modulation. The Nano LR Click Board™ communicates with MCU using the UART interface with commonly used UART RX and TX pins with the hardware flow control pins UART CTS, RTS, RI (Clear to Send, Ready to Send, and Ring Indicator). Besides these pins, Nano LR Click has also GP1 and STAT pins, which are routed to the PWM and AN pins of the mikroBUS™ socket, respectively. STAT pin is also wired to a separate LED indicator labelled as STAT to enable quick and easy module status indication. The Nano LR Click Board™ features the U.FL antenna connector with an impedance of 50Ω, so it can be equipped with the appropriate antenna that MikroE has in its offer. The Nano LR Click Board™ is designed to work with 3.3V only. When using it with MCUs that use 5V levels for their communication, a proper level translation circuit should be used.

We provide a library for the Nano LR Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from compilers IDE(recommended way), or downloaded from our LibStock, or found on the mikroE Github account.
This library contains an API for the Nano LR Click Board™ driver.
void nanolr_cfg_setup ( nanolr_cfg_t *cfg ); - Config Object Initialization function.NANOLR_RETVAL nanolr_init ( nanolr_t *ctx, nanolr_cfg_t *cfg ); - Initialization function.void nanolr_default_cfg ( nanolr_t *ctx ); - Click the Default Configuration function.This example reads and processes data from Nano LR Click Board™s.
The demo application is composed of two sections :
void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
nanolr_process( );
#endif
#ifdef DEMO_APP_TRANSMITTER
nanolr_send_data( &nanolr, TEXT_TO_SEND, strlen( TEXT_TO_SEND ) );
log_printf( &logger, "The message "%s" has been sent!rn", ( uint8_t * ) TEXT_TO_SEND );
log_printf( &logger, "------------------------------------------------------------rn" );
Delay_ms( 2000 );
#endif
}
The full application code, and ready for use projects can be installed directly from the compiler's IDE (recommended) or found on the LibStock page or mikroE Github account.
Other mikroE Libraries used in the example:
Depending on the development board you are using, you may need a USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
The Nano LR Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
