MeshCore App: Radio Settings and Position

Radio Settings

Access via Settings → Radio (or Device → Radio Config depending on app version).

Preset Selection

The most important radio setting. Always use the preset that matches your local network:

• USA/Canada (Recommended) - North American standard: 910.525 MHz, SF7, BW62.5 kHz, CR5. Use this unless your local community uses something different.
• Europe - 868 MHz band preset. Only for EU hardware and EU-region networks.
• Custom - Manual parameter entry. Only use if you know exactly what you're doing and why.

Do not use Custom preset unless your network coordinator specifically instructs you to. Incorrect custom settings make your node invisible to the rest of the network.

TX Power

Transmit power in dBm. Higher power = more range and more power consumption. Maximum legal limit in the US: 30 dBm (1W) conducted. If you have a high-gain antenna, reduce TX power to keep EIRP within 36 dBm (4W). The app displays the maximum for your hardware; leave at default unless you have a specific reason to reduce it.

Hop Limit

Maximum hops for advertisements. Default is appropriate for most deployments. Increase to 5 only on large networks where edge nodes are not discovering repeaters with default settings.

Position Settings

Access via Settings → Position.

Enable GPS

If your device has a GPS module, enable it here. GPS provides position for the contact map and enables distance calculation in the contacts list. On fixed infrastructure nodes, GPS is optional if you configure a static position manually.

Fixed Position

For nodes without GPS, or for fixed repeaters where GPS accuracy is not needed:

1. Enable "Fixed Position"
2. Enter latitude, longitude, and altitude (meters above sea level)
3. Tap Save - the node will broadcast this position in its advertisements

Use your actual deployment coordinates, not your home address. The position is broadcast to the network and appears on community maps.

Position Privacy

If you don't want your position broadcast on the public network, either disable position reporting or set position precision to a reduced value (gives approximate location rather than exact coordinates). Infrastructure operators typically share full position; personal nodes may prefer reduced precision.

Advertisement Settings

• Advertisement Interval - How often your node broadcasts its existence. Default 720 minutes (12 hours) is appropriate for stable deployments. Reduce to 60 minutes during initial setup to confirm discovery.
• Advertisement Hops - How far your advertisement propagates. 0 = local only; 3+ = network-wide. For community repeaters, set to 3 or higher for network-wide visibility.
• Node Name - Your node's display name. Use a consistent format with your community's naming convention.
