LR 14 Click is a compact add-on board for low-power, long-range wireless communication in IoT networks. This board features the RAK3172, a Class A/B/C LoRaWAN 1.0.3-compliant module from RAKwireless Technology, featuring the STM32WLE5CC ARM Cortex-M4 32-bit chip. This board supports LoRaWAN and LoRa Point-to-Point communication modes and integrates multiple frequency bands for flexibility across various regions. Key features include UART, SPI, and I2C interfaces, a USB Type-C connector for power and configuration, and a rechargeable battery option for standalone operation.
We provide a library for the LR 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 LR 14 Click driver.
lr14_cfg_setup
Config Object Initialization function. lr14_init
Initialization function. lr14_cmd_run
This function sends a specified command to the Click module. lr14_cmd_set
This function sets a value to a specified command of the Click module. lr14_cmd_get
This function is used to get the value of a given command from the Click module. This example demonstrates the use of LR 14 Click board by showing the communication between two Click boards configured in P2P network mode.
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 factory reset and reads system information.
Configures device for the LoRa P2P network mode.
Performs a LoRa P2P example by exchanging messages with another LR 14 Click board.
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.
Other Mikroe Libraries used in the example:
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.
