Programming​

Development Environment Setup​

To start developing applications for the FoBE Core nRF52840 Mesh, you'll need to set up a development environment. Here are the recommended steps:

  1. Install the Arduino IDE: Download and install the latest version of the Arduino IDE from the official Arduino website.
  2. Install the Board Support Package (BSP): Add the necessary board support package for the nRF52840 to the Arduino IDE. This will allow you to compile and upload code to the module.
  3. Install LoRaWAN library: You can use the MCCI LoRaWAN LMIC library to develop LoRaWAN applications.

Example Code​

Here's a simple example of sending a LoRaWAN message using the FoBE Core nRF52840 Mesh:

// filepath: example.cpp
#include <lmic.h>
#include <SPI.h>

Note: This is a basic example and may require adjustments based on your specific LoRaWAN network and configuration.
