Ghost Mode ​
S01E06 — "You can now haunt the Bluetooth spectrum."
TL;DR Ghost Mode broadcasts a fake BLE beacon from your phone. You appear in other devices' Bluetooth scanners — including Apple's BT Settings — as a connectable device with a random pseudonym. The pseudonym changes every session.
What it does ​
Your phone becomes a BLE advertiser. It broadcasts a connectable advertisement with a generated pseudonym as the device name. Any BLE scanner nearby — including iOS Bluetooth Settings, nRF Connect, and other NearTrace instances — will see you as a separate device.
This is real BLE advertising using Android's BluetoothLeAdvertiser. The phone's own Bluetooth name is not changed — only the advertisement payload carries the pseudonym.
Starting Ghost Mode ​
- Open the Ghost Mode tab (bottom nav)
- Tap Start Broadcasting
- Your current pseudonym is shown — it changes each session for plausible deniability
Use cases ​
- Testing your own BLE scanner setup — verify your scanner sees what you expect
- Privacy research — observe how other devices react to a new BLE presence
- Demonstrations — show how BLE advertising works without exposing your real device identity
What Ghost Mode does NOT do ​
- Does not spoof another real device's identity
- Does not change your phone's system Bluetooth name (that would persist after a crash)
- Does not broadcast any personal information
- Does not connect to other devices — it advertises as connectable but accepts no connections
WARNING
Ghost Mode is for your own devices and educational purposes. Broadcasting fake identities to deceive or harass others is your responsibility, not ours.
