MeshCrossway on Android

Connect both radios in the app, then choose the conversation or map you want to explore.

You provide the phone and radios. Choose compatible models that suit your setup; a dedicated touchscreen controller is not required.

Two networks, each with its own conversations. MeshCrossway lets you use them side by side. It does not forward messages between Meshtastic and MeshCore.

One setup, many ways to carry it

Ready for your
next outing.

Carry your radios in a pack, use them at home or build a setup for your vehicle. Bluetooth gives you flexibility in where you place them, within connection range.

A real example from the project.

This custom 3D-printed mount was made by MeshCrossway’s creator to hold both radios on a car roof while using the app from the phone. It is an example of a personal setup, not a required accessory or a product included with the app.

Good to know

A few common questions.

Can I use only my phone?

You need external radios to communicate with the mesh networks. To use Meshtastic and MeshCore together, connect two independent compatible Bluetooth radios — one for each network. The phone runs the app; each radio handles its network.

Do I need mobile service or internet?

Radio messages do not need cellular service or internet. You do need internet to download the app and map areas. Download maps before going offline. Message delivery depends on your radio setup, terrain and available mesh coverage.

Do I have to buy a specific radio or the car mount?

No specific brand or car mount is required. Each radio must support its network’s compatible Bluetooth connection. Heltec V3 radios are used in development; other models and firmware combinations need testing. See the compatibility and setup guide on GitHub →

Can someone on Meshtastic talk to someone on MeshCore?

Messages stay on the network you send them through. MeshCrossway brings both networks into one app, but does not bridge or relay messages between them.

Where are the technical details?

Source code, radio requirements, development notes and the separate ESP32 controller project are documented on GitHub. You can also report a problem or suggest an improvement.
