“A device that combines real-time location tracking and two-way pager, over a LoRa mesh network.
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.
Well, here it is!
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.
What it does
Allows field user to set their status to one of 4 colors (Blue, Green, Orange, Red), which commander will see in real-time.
Transmits user’s location to commander in real-time.
Alerts user of incoming messages and broadcasts from commander.
Allows user to send a reply to incoming messages (from a list of options)”
