How to connect Ledger Nano X to a mobile phone? (Bluetooth Setup)

Bluetooth Pairing Process

1. Ensure the Ledger Nano X firmware is updated to version 2.0 or higher using Ledger Live on a computer before attempting mobile pairing.

2. Power on the device by pressing both side buttons simultaneously until the Ledger logo appears.

3. Navigate to the Settings menu using the left button, then select Bluetooth and toggle it ON using the right button.

4. Confirm the action on the device screen by pressing both buttons together when prompted.

5. The Nano X will display a six-digit pairing code—this must match the code shown during pairing on the mobile device.

Mobile Device Preparation

1. Enable Bluetooth in the phone’s system settings and ensure location services are active, as Android requires location access for Bluetooth scanning.

2. Install the official Ledger Live Mobile app from the Apple App Store or Google Play Store—third-party versions are not supported and may compromise security.

3. Grant all necessary permissions requested during installation, including Bluetooth, storage, and notifications where applicable.

4. Restart the mobile device if Bluetooth has been previously unstable or if pairing fails on the first attempt.

5. Keep the phone within one meter of the Ledger Nano X during the entire setup sequence.

Ledger Live Mobile Connection Flow

1. Open Ledger Live Mobile and tap “Get Started” if launching for the first time, or “Add account” if already configured.

2. Select “Hardware wallet” and choose “Ledger Nano X” from the device list.

3. When prompted, tap “Pair device” and wait for the app to detect available Nano X units via Bluetooth.

4. Select the detected device and compare the six-digit code displayed on both the phone and the Nano X screen.

5. Press both buttons on the Nano X simultaneously to confirm matching codes—connection status will update in the app within seconds.

Common Bluetooth Interference Sources

1. Other active Bluetooth devices operating nearby, especially audio headsets or smartwatches transmitting continuously.

2. Physical obstructions such as metal cases, wallets, or thick phone covers that attenuate the 2.4 GHz signal.

3. Wi-Fi routers or microwave ovens emitting noise in adjacent frequency bands causing packet loss.

4. Low battery on the Nano X—ensure charge level remains above 20% before initiating pairing.

5. Outdated Bluetooth stack drivers on older Android models, particularly those running Android 8 or earlier without vendor updates.

Frequently Asked Questions

Q: Can I use Ledger Nano X with multiple phones simultaneously via Bluetooth?No. The device maintains only one active Bluetooth pairing at a time. To connect to another phone, the previous pairing must be manually cleared from the Nano X Bluetooth settings.

Q: Why does Ledger Live Mobile show “Device not found” even though Bluetooth is enabled?This often occurs when the Nano X is locked or in sleep mode. Wake the device by pressing both side buttons, then reinitiate pairing from the app.

Q: Is Bluetooth communication encrypted between the Nano X and mobile app?Yes. All Bluetooth data exchanges use AES-256 encryption and are authenticated through secure key derivation protocols embedded in the Secure Element.

Q: Does using Bluetooth expose my private keys to remote attackers?No. Private keys never leave the Secure Element. Bluetooth transmits only signed transaction payloads and metadata—not raw key material.
