Simplified Off-Grid Group Setup via Shared QR Code

[gitpyblog]

Problem

Currently, setting up a small group of friends for off-grid communication requires multiple manual configuration steps (device setup etc.). For non-technical users this can feel overly complex and may discourage adoption in real-life scenarios (e.g. outdoor trips, events, emergency prep).

In time-sensitive situations (e.g. local emergency coordination), the need for fast and simple onboarding becomes even more critical.

Proposed Solution

Introduce a simplified “Off-Grid Group Mode/Camping Mode” that works as follows:

1. One person generates a Group QR Code.
2. Other users scan this QR code.
3. Their radios automatically:
   • Join the same predefined group
   • Switch to a restricted communication mode
   • Only handle traffic from that selected group

After scanning, devices would operate in a simplified state:

• Only selected group traffic is processed
• No need for manual filtering (Contacts that have not joined the private group should be visually greyed out)
• Minimal configuration steps

Use Case Examples

1. Private Outdoor Group

• A group of 5 friends goes hiking
• They enable “Off-Grid Mode”
• One person shows a QR code
• Everyone scans it
• All devices are instantly aligned to one group

Result:

• No manual channel configuration, no advanced settings required.

2. Rapid Emergency Coordination

Scenario: A temporary local coordination point (e.g. after a storm or infrastructure failure).

• An organizer generates a QR code for a temporary coordination group
• The QR code is displayed at a physical meeting point
• Volunteers arriving on site scan the QR code
• Their devices automatically join the coordination group and switch to restricted group-only mode
• Upon joining, users may optionally receive a short initial instruction screen (basic coordination guidelines)

Result:

• Fast onboarding.
• Reduced confusion.
• Clear and contained communication scope without manual configuration.

Benefits

• Reduces setup friction
• Makes MeshCore more accessible for non-technical users
• Improves real-world usability in outdoor / emergency scenarios
• Encourages adoption beyond the technical community

Open Questions

Should this be a separate mode or a simplified preset?
Should scanning override existing group config or create a temporary session?
Should there be an easy way to revert back to full mode?
