Map the mesh
as you move and
find hidden nodes.
Pair your companion to the RX webapp. Every packet your radio hears lands on the shared map, next to what every other mapper heard.
- Find hidden LoRa traffic sources
- Map repeater coverage
- Analyze on the desktop map
- Free, code on GitHub
The RX webapp. It pairs with your MeshCore companion over Web Bluetooth and logs every packet it hears, placed with your phone's GPS. The HUD reads out the last reception, and on the road the readout floats on top of your navigation app. Open the RX webapp →
The map. Every mapper's receptions meet on one coverage map, so you see what a node reaches beyond your own radio. Reading it takes no account. See the map →
Hunt & Locate. Find a hidden LoRa source: a node that fills the air with packets that carry no path and no name, so only its signal gives it away. Follow the signal, and Locate turns the receptions into a search area, inferred from RSSI and SNR, not from GPS tracking of the node. How positions work →
Reach. How far one repeater gets through: a ray from where its receptions put it to every place it was heard, next to the position it advertises. Positions are inferred from RSSI and SNR, not from GPS tracking of the node. How positions work →
Measured, not guessed.
Every hex on the map is a real reception with RSSI and SNR, logged by a volunteer with a radio. No modelled coverage.
