Your next step:
connect your radios.

What you need

• An Android phone with Bluetooth.
• One compatible radio running Meshtastic.
• A second, independent compatible radio running MeshCore Companion BLE firmware.

Your phone connects directly to both radios. You do not need the separate touchscreen controller or a special car mount. You choose and provide your radios; Heltec V3 radios and a Samsung S25 are used in development, and other combinations need testing.

Each network keeps its own messages and contacts. MeshCrossway does not forward messages between Meshtastic and MeshCore.

Install. Connect. Explore.

1. Download the app on your phone. Use the APK download button above. Open the downloaded file and allow installation from your browser or file manager when Android asks.
2. Allow Bluetooth access. Grant nearby-device and location permissions when requested so the app can find your radios and use GPS features.
3. Connect your Meshtastic radio. Close any other app connected to that radio. Open Settings in MeshCrossway, select Meshtastic and choose your device.
4. Connect your MeshCore radio. Repeat for MeshCore with your second radio. Wait for both networks to finish loading.
5. Try a conversation. Check that each network is ready, send a test message and explore the contacts and map.

Updating an existing app? Install over your current version and choose Update to keep your data. Do not uninstall or clear storage. If you are still using version 0.2.2 or earlier, follow the backup and migration guide first.

New in 0.4.8: let the map follow you.

Tap GPS to keep your phone in view as you move. Dragging the map pauses following; tap GPS again to resume. A blue arrow shows your direction of travel when movement is clear, returning to a dot when stopped or when direction is uncertain.

Recent updates also make compatible MeshCore repeater settings easier to edit: sign in as an administrator, tap a setting and save. Available options depend on the repeater firmware.

This remains a beta, with field testing pending for the latest changes. For detailed changes, repeater limitations and previous releases, see the project status and release history.

Heading somewhere without service?

Radio messages do not need cellular service or internet. Download your map areas while online, then check that they open offline before your trip. Delivery depends on your radio setup, terrain and available mesh coverage.

The app is still a beta. Compatibility and reliability are being improved across phones, radios and firmware versions. It should not be your only means of communication in an emergency.
