LR 11 Click - 915MHz is a compact add-on board for long-range, low-power wireless communication in IoT applications. This board features the 453-00139R, an ultra-low power LoraWAN module Ezurio (part of the RM126x series), integrating the Silicon Labs EFR32 SoC and the Semtech SX1262 radio. It supports LoRaWAN classes A, B, and C, offering secure, scalable, and bi-directional communication. It operates in the 902-928MHz frequency range with a typical transmit power of up to 22dBm and a communication range of up to 15km.
We provide a library for the LR 11 915MHz 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 11 915MHz Click driver.
lr11915mhz_cfg_setup
Config Object Initialization function. lr11915mhz_init
Initialization function. lr11915mhz_reset_device
This function resets the device by toggling the reset pin logic state. lr11915mhz_cmd_run
This function sends a specified command with or without parameters to the Click module. lr11915mhz_cmd_set
This function sets a value to a specified command parameter of the Click module. This example demonstrates the use of LR 11 915MHz 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 11 915MHz Click board. One device should be set to NODE_0_ADDRESS, and the other to NODE_1_ADDRESS.
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.
