Meshtastic supports two communication modes: channel broadcasts and direct messages.

Channels are shared communication groups. All nodes configured with the same channel key can read and send messages on that channel.

Every Meshtastic device comes with a default LongFast channel. This is an unencrypted channel used for general mesh communication.

Channels support multiple encryption levels:

│ 🔒 Security Tip: Always configure a unique PSK for private communications. The default channel is

│ intentionally open so new users can discover the mesh — but you should create a separate

│ encrypted channel for anything sensitive.

1. Navigate to Settings → Channels.

2. Tap Add Channel or scan a QR code.

3. Configure the channel name and encryption key.

4. Share the channel URL/QR code with others who need access.

Tapping a channel shows its details and sharing options.

Direct messages (DMs) are point-to-point encrypted communications between two specific nodes.

1. Open the Messages tab.

2. Select a node from your contacts list or tap a node in the node list.

3. Type your message and tap Send.

When a message fails to deliver, the error indicator shows what went wrong:

│ 💡 Tip: Most delivery errors resolve themselves. If a node is intermittently reachable, the mesh

│ will retry. For persistent "No Route" errors, check that intermediate Router nodes are online.

Pre-configured messages for rapid communication:

• Access via the Quick Chat button in the message input area

• Choose from built-in phrases or custom messages

• Customize quick chat messages in Settings → Quick Chat

• Useful when typing is impractical (gloves, small screen, urgent)

!Quick chat option

The channel list shows each channel with its latest message preview.

Messages appear as chat bubbles — sent messages on the right, received messages on the left. Each bubble shows the sender, timestamp, and delivery status. Messages with replies include a quoted preview of the original message above the response.

React to messages with emoji:

• Long-press a message to open the actions menu

• Tap Add Reaction to choose an emoji

• Reactions appear below the message bubble

• Multiple users can react to the same message

• React to your own messages or others' messages

!Emoji reaction badges displayed beneath a message

│ 💡 Tip: Reactions are lightweight — they use minimal mesh bandwidth compared to full text

│ messages.

Long-press any message to access:

• Copy — copy message text to clipboard

• Reply — quote the message in your response

• React — add an emoji reaction

• Delete — remove a message you sent (local deletion)

Messages are queued and transmitted based on priority:

1. Emergency/alert messages (highest)

2. Direct messages

3. Channel broadcasts (lowest)

• Maximum length: 237 bytes (approximately 230 characters for ASCII text)

• Rate limiting: The mesh enforces airtime fairness; heavy message volume may be throttled

• Delivery: Messages are retried automatically if no acknowledgment is received

• Use channels for group coordination

• Use direct messages for private person-to-person communication

• Keep messages short — mesh bandwidth is limited

• Configure encryption for sensitive communications

• Nodes — tap a node to start a direct message

• Settings — Radio & User — configure channel encryption and presets

• MQTT — bridge channel messages to the internet

• Channel configuration — detailed channel settings on meshtastic.org
