How a drive works

  1. Your phone pings. Paired with your MeshCore radio, MeshSonar sends a short ping on the #wardriving channel as you drive.
  2. Repeaters echo it. Any repeater that hears the ping repeats it. For about 6 seconds your radio listens for those echoes and notes which repeater it heard, and how strongly (SNR).
  3. The app records who heard you. Each ping becomes a point: where you were and which repeaters answered, or that none did. "Heard nothing" is data too.
  4. This site maps it. Uploaded pings are summed into squares of about 220 m on the coverage map and checked against the model.
A phone and radio send a ping; two repeaters in range echo it back, a third out of range does not.youheard youheard youout of range

Set up in four steps

  1. Install

    Install MeshSonar on your phone from meshsonar.com/app.

  2. Pair your radio

    Turn on your MeshCore companion radio and pair it over Bluetooth in the app. Join the #wardriving channel.

  3. Get a driver key

    Sign in here and create a driver key on Devices and keys, then enter it in the app. Or request a key from inside the app.

  4. Drive

    Start a drive and go. Every ping is saved on the phone first and uploaded when you have signal, so nothing is lost in a dead zone.

Your privacy

Trimmed endsThe first and last 500 m of every drive are left off public maps, so your driveway never shows. Change the distance on Privacy.
Privacy zonesDraw circles around home or work; pings inside them are never shown publicly.
AnonymousDrive as "anonymous" and your callsign never appears next to your drives.
What's publicOnly squares of about 220 m with counts and signal levels. No raw tracks, no drive names, times rounded to the hour.
LeaderboardOff unless you opt in, and then by callsign only.
Your dataYou see your own drives untrimmed, and can rename, hide, export or delete them at any time.
