We have decided to use the HopeRF RFM9x 433/915 MHz LoRa modules for longer distance links and WiFi for shorter links. We are currently developing a software wrapper for the radio modules which presents the same MQTT-like interface regardless of which mode is being used. This will enable us to easily add support for different… Continue reading Spring 2025 Update

This semester we have gotten the radios we purchased to work and run a test script using Arduinos. We are now trying to get the radios to work with Raspberry Pis, however, we have encountered numerous issues in the process.

Currently, the RFM95W and RFM69HCW transceivers were chosen for testing as these two options are affordable, long-range, and come with Arduino libraries from Adafruit so development for these transceivers should be more straightforward than other solutions. If there are any other transceivers that you know of or are familiar with that would be appropriate for… Continue reading Current Plan
