In 2017, Hurricane Maria, a category-5 storm, severely impacted Puerto Rico, demolishing homes and communication infrastructure. To address this issue, the ClusterDuck Protocol (CDP) was developed in 2018. It utilizes battery-powered Internet-of-Things devices to reestablish essential communication during emergencies, allowing civilians to request assistance, share their locations, and receive vital information from local governments and responders.
The ClusterDuck Protocol runs on a variety of IoT hardware, including many ESP32 Arduinos.
Here is a list of hardware we use, though there may be many others that work. We recommend the Heltec LoRa ESP32 and the TTGO T-Beam ESP32.
For a simple network you will want to make at least two Ducks. For bigger networks you will need more.
To start developing, you will need PlatformIO on your computer.
Download or git clone the CDP library from GitHub.
Follow the installation instructions here
Please Note: With the Release of the ClusterDuck Protocol Version 4 we have different instructions. If you are looking for older instructions please go here
