Connecting to Your Device

The MeshCore CLI (meshcore-cli) supports three connection methods. Choose the one that matches your hardware and situation.

Serial (USB)

The most reliable method. Connect your device via USB and use the default baud rate:

meshcore-cli

The CLI auto-detects the serial port on most systems. If you have multiple serial devices:

meshcore-cli --port /dev/ttyUSB0   # Linux/macOS
meshcore-cli --port COM3            # Windows

Baud rate: 115200

Connect wirelessly to a nearby device. The device must have BLE enabled:

meshcore-cli --ble connect

If the device does not appear, ensure it is powered on and not already connected to the MeshCore app. Only one BLE client can connect at a time.

Connect to a device that exposes a TCP interface (useful for remote administration of fixed nodes):

meshcore-cli --tcp 192.168.1.100:4403

Replace the IP and port with the device’s actual address. Port 4403 is the MeshCore default.

Once connected, run info to confirm the connection and see device details:

Expected output includes firmware version, battery level, node name, and radio configuration.
