ResQMesh

When the network is gone,
the radios keep talking.

Small LoRa boards and your iPhone become one network. Messages, positions and emergency alerts hop from board to board, with no internet and no infrastructure behind them.

App coming soon · firmware in beta
What it does

Built for the moment it is needed.

EMERGENCY
ALERT
One button carries your position to everyone within reach. The network repeats it until somebody confirms, and the confirmation comes back to you.
MESSAGES
Messages that arrive
Channels and private messages, with delivery confirmation. Every board relays what it hears, so range grows with the team.
POSITION
Everyone on the map
Automatic positions, tracks, distance and bearing to each node — and turn-by-turn navigation to whoever called for help.
CARPLAY
Hands on the wheel
Alerts on the lock screen and on CarPlay, sending and reading by voice with Siri, ALERT from the Action button even with the phone locked.
APRS
Amateur radio, properly
On 433 MHz it lives alongside the APRS network, with beacons and messages; on the licence-free 868 MHz band it works with no licence at all.
SETUP
Nothing to set up
The team shares frequency and radio settings with a QR code, after measuring which channel is quietest right there.
On the phone

Come si presenta.

ALERT ricevuto con distanza, batteria e navigazione
An ALERT arrives even with the phone locked: who sent it, how far, which fix, what battery is left.
Impostazioni della scheda radio
The board is set up from the phone: callsign, work mode, channel, radio parameters.
Rilievo dei canali
Before choosing a frequency, the board listens: which channel is quietest, right where you are.
Profilo di rete come codice QR
The team shares frequency and settings with a QR code. Callsigns stay personal.
Firmware · beta

Put it on your board.

The board firmware is free and stays free. Connect the board with a USB data cable and pick your model. Boards with an ESP32 are programmed straight from the browser: Chrome or Edge on a computer, not from a phone.

For the two nRF52 boards: connect the board, press the reset button twice in quick succession — a removable disk appears — and drag the .uf2 file onto it. The board restarts on its own with the new firmware.

Installing wipes the previous configuration: callsign, frequency and channels are set again from the app. On amateur radio bands a licence is required.
