Recommended: Read our Default Configuration Guide first. It explains why default settings are important and provides step-by-step setup instructions.
Watch: Introduction videos explaining Meshcore basics
Basic Configuration
Device Name
Set your device name to something identifiable and location-based:
- Fixed Repeaters: Use location (e.g., "Eureka-Downtown-RPT", "Eureka-Hill-RPT")
- Mobile Nodes: Include "Mobile" in the name (e.g., "Eureka-Mobile-John")
- Personal Nodes: Use a recognizable name (e.g., "Eureka-YourName")
Region Settings
Region: US (902-928 MHz)
Frequency Slot: Default (or coordinate if setting up repeater)
LoRa Configuration
Important: Use Default Settings!
| Setting | Value | Notes |
|---|---|---|
| Spreading Factor | SF10 (default) | Do not change - provides excellent range with good data rates |
| Bandwidth | 250 kHz (default) | Do not change |
| Coding Rate | 4/8 (default) | Do not change |
| Transmit Power | 22 dBm (maximum) | Keep at maximum for best range |
Channel Configuration
Configure these channels to participate in the Eureka Mesh network:
| Channel Name | Purpose | PSK/Key |
|---|---|---|
| #eureka | Primary local community channel | Default (AQ==) |
| #montana | State-wide coordination | Default (AQ==) |
| #general | General chat and discussion | Default (AQ==) |
| #emergency | Emergency communications only | Default (AQ==) |
| #test | Testing and diagnostics | Default (AQ==) |
- Keep #emergency clear for actual emergencies
- Use #test for range tests and configuration checks
- Be respectful and helpful on all channels
Position Configuration
Important: Always configure your device's position data. This helps with:
- Network planning and coverage analysis
- Emergency coordination
- Finding nearby nodes
- Useful visualizations in the Meshcore app
GPS Settings
For devices with GPS:
- Enable GPS in settings
- Set update interval (recommend 2-5 minutes for mobile, 15-30 minutes for fixed)
- Broadcast position to relevant channels
Manual Position
For devices without GPS or fixed installations:
- Find your coordinates using Google Maps or similar
- In the Meshtastic app: Settings → Position → Set Fixed Position
- Enter latitude and longitude
- Set altitude if known (improves accuracy)
Repeater Configuration
If you're setting up a fixed repeater for the network:
Router Mode
Enable Router mode in Device Config → Device Role → Router
This optimizes the device for message forwarding and reduces power consumption by disabling unnecessary features.
Power Settings
- For Solar/Battery: Optimize power settings, consider lower broadcast power if coverage is adequate
- For Mains Power: Can use higher power settings for maximum coverage
Clock Synchronization
New repeaters need time synchronization for proper operation:
- Via App: Settings → Device → Sync Time
- Via CLI: Run command "clock sync"
Antenna
Use a proper outdoor antenna mounted as high as possible:
- Omnidirectional antenna recommended
- 5-9 dBi gain typical
- Use quality coax cable (low loss)
- Keep cable runs short
- Weatherproof all connections
Guest Access
If you're configuring a public node that allows guest connectivity:
- Create a channel named "guest"
- Set the password to "guest"
- This provides a standardized way for visitors to connect
Current Network
Repeaters
| Name | Location | Coordinates | Status |
|---|---|---|---|
| Eureka-RPT-01 | First deployment location | 48°54'20.0"N 115°04'34.9"W | Operational |
| Eureka-Solar-RPT | TBD - Planning phase | TBD | Planned |
Coverage Map
Coverage map coming soon - we're conducting field testing to map actual coverage areas.
Testing Your Setup
- Join the #test channel to verify your configuration
- Send a test message and wait for responses from other nodes
- Check signal quality - aim for SNR above 0 dB for reliable links
- Report your results in the community discussion
Troubleshooting
Can't See Any Nodes
- Verify region is set to US
- Check antenna is properly connected
- Ensure you're within coverage area (check coverage map)
- Try from different locations (outdoors, elevated)
Messages Not Sending
- Check channel configuration matches network settings
- Verify device has valid time (sync clock)
- Ensure device firmware is up to date
- Check for "Air Util" too high (network congestion)
Poor Range
- Check antenna connection and placement
- Verify transmit power settings
- Try from elevated location or outdoors
- Buildings and terrain significantly affect range
