Offline SOS via Bluetooth (Upcomming)

In future updates, the SOS App will introduce Offline SOS via Bluetooth — allowing users to send emergency alerts even without mobile networks or Wi-Fi connectivity.

This feature is designed to extend your safety network by leveraging Bluetooth-enabled trusted devices nearby.

Overview​

Offline SOS via Bluetooth enables your phone to:

  • Broadcast emergency alerts using Bluetooth Low Energy (BLE) signals.
  • Detect and relay SOS messages to trusted contacts within Bluetooth range.
  • Operate without reliance on mobile data, SMS, or internet connections.

The system is inspired by modern peer-to-peer (P2P) mesh networking models like Find My Device by Google.

How It Works​

StageDescription
BroadcastYour device emits a secure, encrypted emergency signal via Bluetooth.
DetectionNearby trusted devices with the SOS App installed receive the broadcast.
RelayReceiving devices can forward your alert using their internet connection if available, or hold it until connected.
NotificationYour emergency contacts are notified through the quickest available channel (SMS, Internet, or held queue).
info

The system is completely decentralized. No central server processes your Bluetooth emergency data.

Requirements​

  • Bluetooth Access:
    SOS App will require permission to use Bluetooth and run Bluetooth services in the background.

  • Trusted Devices Nearby:
    Trusted devices must have the SOS App installed and have Bluetooth active.

  • Battery Management:
    Exempt the SOS App from aggressive battery optimizations to ensure uninterrupted Bluetooth broadcasting.

  • Location Services:
    On many devices, Bluetooth scanning also requires Location Services to be enabled.

Setup Guide (Coming Soon)​

The setup process is expected to involve:

  1. Opening SOS App → Offline SOS Settings.
  2. Enabling Offline SOS via Bluetooth toggle.
  3. Granting necessary Bluetooth permissions.
  4. Choosing to allow trusted devices automatically or manually approving them.
  5. Optionally setting Bluetooth SOS to activate automatically when network loss is detected.
tip

A detailed guide with visuals will be available after the official feature release.

Expected Use Cases​

  • Remote Travel:
    Hiking, camping, or trekking in no-signal zones.

  • Urban Blackouts:
    During disasters like earthquakes where cellular towers may fail.

  • Accidental Network Drop:
    In elevators, basements, remote highways.

  • Silent Emergency Networks:
    Broadcast to nearby people discreetly without triggering alarms.

Common Questions​

Will Offline SOS work automatically if the network is lost?

Yes. Once enabled, the SOS App will automatically switch to Bluetooth broadcasting if mobile data and Wi-Fi are unavailable.

What is the maximum range of Bluetooth SOS signals?

Typical Bluetooth Low Energy range is approximately 30–100 meters depending on environment and device hardware.

Can strangers pick up my SOS signal?

No. Only trusted devices paired with your SOS App account will recognize and relay your emergency alert securely.

Does Offline SOS work when the phone is locked?

Yes. Background services will ensure SOS broadcasting continues even if the device screen is off or locked.

Troubleshooting (Coming Soon)​

When the feature launches, expected troubleshooting tips will include:

  • How to test Bluetooth broadcasting.
  • What to do if nearby devices aren't detecting your SOS.
  • How to reset trusted device pairings.
  • Optimizing battery performance with Offline SOS enabled.

Offline SOS via Bluetooth enhances your safety by providing an alternative communication method when traditional networks fail.
It empowers users to stay connected even in the most isolated or critical conditions.

This upcoming feature ensures that no matter where you are — help is always within reach.
