Ledger Live for Android with Bluetooth Connection Guide
To establish a secure link between your offline crypto storage and smartphone, enable wireless pairing in the app settings. This allows transaction signing without exposing private keys to internet-connected environments. Current firmware version 2.1.0 supports this feature on devices manufactured after Q2 2021.
The wireless protocol establishes an encrypted channel using 256-bit AES cryptography. Each session generates temporary keys that expire after 15 minutes of inactivity. For optimal security, disable automatic reconnection in advanced preferences.
When performing operations, the app displays device-specific identifiers that must match your hardware unit’s screen. Mismatched IDs indicate potential interception attempts – immediately terminate such sessions. Battery consumption during active use averages 8-12% per hour on modern smartphones.
How does wireless verification protect against attacks?
The system implements several safeguards against common vulnerabilities. Man-in-the-middle attempts are prevented through certificate pinning that validates the hardware’s unique fingerprint before establishing any data transfer channels.
Timing attacks are mitigated by introducing random delays in the cryptographic operations. Each command requires explicit physical confirmation via the device’s buttons, preventing unauthorized bulk operations.
What requirements must your setup meet?
Your hardware must run firmware 2.0.4 or later, detectable through the management interface. The companion application needs at least API level 28 (Android 9) with unrestricted background data permissions.
Devices with modified operating systems or rooted access automatically terminate connections. Some battery optimization features in manufacturer UI skins may require manual whitelisting of the wallet application.
Troubleshooting common connectivity failures
Persistent pairing issues often stem from interference in the 2.4GHz spectrum. Switching off nearby WiFi routers, microwaves, or wireless peripherals frequently resolves unstable connections.
If the hardware fails to appear in discovery mode, reset its wireless module by holding both buttons for 12 seconds until the indicator flashes orange. This clears cached pairing data without affecting stored cryptographic material. See also: device unboxing inspection.
