I have been contacted by a number of people in search and rescue (SAR) who are interested in the other Ripple LoRa mesh projects I have been working on, and it got me to thinking about making a dedicated device for the field personnel.This device doesn’t require a companion Android handset, as it has a very simple UI for the user. It has a small OLED screen and just 3 push buttons, so only offers limited types of interaction with the user.
