RBaken radar firmware
The radar shows every teammate's direction and distance on your Meshtastic node's own screen: the closest ones in a list, everyone on a minimap that turns with you when the board has a compass. No phone or app needed in the field, and it works with any Meshtastic node on the same channel.
It is free and open source under the GPL-3.0. I am working to make the radar part of the official Meshtastic firmware: the changes are in review as pull requests, and that takes time. Want to try it now? The builds are below.

Check your settings
The radar only shows teammates whose nodes can hear yours. Check these on every device in the group.
- Same channel and radio mode - Use the same channel name, key and LoRa radio mode (such as LongFast) on every node. Nodes on a different radio mode cannot hear each other.
- Precision Location on - In the channel's position settings, turn on Precise Location. With a rounded-sm position, the radar can only show rough distances to teammates.
- An update rate that fits - Choose how often nodes share their position: more often keeps the radar fresh but costs airtime and battery. Work it out in the Configuration planner.
Radar settings survive a reboot. Going back to stock: flash any official release from the web flasher the same way.
