Why Ledger Bluetooth Stops Working
Before jumping into fixes, it helps to understand what’s actually going wrong. Bluetooth issues with Ledger devices typically fall into a few categories:
Understanding the root cause helps you pick the right fix faster. That said, the fixes below are ordered so that the most common causes are addressed first.
Fix 1: Restart Bluetooth on Your Phone
This sounds too simple, but it resolves a surprising number of Bluetooth connection failures. The Bluetooth stack on both iOS and Android can accumulate errors over time, and a restart clears them.
On iPhone/iPad:
On Android:
- Pull down the notification shade
- Tap the Bluetooth tile to turn it off
- Wait 10 seconds, then tap again to enable
If this doesn’t work within two connection attempts, move to Fix 2.
Fix 2: Forget the Device and Re-Pair from Scratch
A corrupted pairing record is one of the most common causes of persistent Bluetooth failures. Removing the old pairing and starting fresh often resolves what looks like a deeper problem.
Step 1 — Remove from your phone’s Bluetooth settings:
Step 2 — Clear pairing on the Ledger itself:
On the Nano X: Go to Settings > Bluetooth and select Forget all paired devices (or remove individual devices if that option is shown).
On the Stax: Navigate to Settings > Bluetooth > Paired devices and remove your phone from the list.
Step 3 — Re-pair:
Open Ledger Live on your phone, go to My Ledger, and initiate a new Bluetooth pairing. Confirm the pairing code displayed on both devices.
Fix 3: Update Ledger Firmware
Bluetooth behavior is heavily tied to firmware. Ledger regularly releases firmware updates that fix connectivity bugs, improve pairing stability, and address compatibility issues with newer versions of iOS and Android.
To check and update your firmware:
- Allow the Manager to connect to your device
- Follow the on-screen prompts; the device will restart and reinstall apps automatically
After updating, disconnect the USB cable and test Bluetooth again.
Current firmware versions (as of early 2026):
| Device | Latest Firmware |
|---|---|
| Nano X | 2.4.0 or later |
| Ledger Stax | 1.4.0 or later |
If you’re below these versions, update immediately before troubleshooting further.
Fix 4: Update the Ledger Live Mobile App
An outdated Ledger Live app on your phone can cause Bluetooth handshake failures even when the firmware is current. The mobile app and firmware need to be compatible versions.
After updating, force-close the app completely (swipe it away in your app switcher), reopen it, and attempt a fresh connection.
Fix 5: iOS vs Android — Platform-Specific Issues
Bluetooth behaves differently between Apple and Google’s ecosystems. Some issues are platform-specific.
iOS-Specific Issues
Location permissions: On iOS, apps that use Bluetooth for device scanning are required to request location permissions. This is an Apple requirement, not a Ledger choice. If you denied location access when first installing Ledger Live, Bluetooth scanning will silently fail.
Fix: Go to Settings > Privacy & Security > Location Services > Ledger Live and set it to While Using the App.
Background app refresh: If Ledger Live gets suspended in the background, it can drop the Bluetooth connection. Go to Settings > General > Background App Refresh and enable it for Ledger Live.
iOS 17+ Bluetooth privacy changes: Apple tightened Bluetooth permissions in iOS 17. Go to Settings > Ledger Live and make sure Bluetooth is toggled on.
Android-Specific Issues
Nearby devices permission: Android 12 and later requires explicit permission for Bluetooth device scanning. Go to Settings > Apps > Ledger Live > Permissions and enable Nearby devices.
Battery optimization killing the app: Android’s aggressive battery management can kill Bluetooth connections. Go to Settings > Battery > Battery optimization, find Ledger Live, and set it to Don’t optimize or Unrestricted.
Bluetooth scanning restriction: Some Android manufacturers (Samsung, Xiaomi, OnePlus) add extra battery/background restrictions. Check your manufacturer’s specific battery settings and whitelist Ledger Live.
Fix 6: Use USB-C Instead of Bluetooth
If you’ve worked through all the above fixes and Bluetooth still isn’t connecting reliably, the pragmatic solution is to switch to USB. Both the Nano X and Stax support USB-C connections to desktop and — with the right cable — to Android phones.
USB-C to phone: You’ll need a USB-C OTG cable or adapter. Most modern Android phones support this natively. Connect your Ledger to your phone via USB-C, then open Ledger Live mobile — it should detect the device automatically in wired mode.
iOS (iPhone/iPad): Apple devices require a Lightning-to-USB-C adapter (older iPhones) or USB-C directly (iPhone 15 and later, iPad Pro). Use a quality cable and the connection is typically rock-solid.
USB is also faster and more secure for firmware updates, so it’s worth having a cable handy regardless.
Additional Troubleshooting Steps

FAQ
Why does my Ledger Nano X keep disconnecting from Bluetooth?
The most common cause is Android’s battery optimization killing the Ledger Live process. Whitelist the app in your battery settings. On iOS, make sure Background App Refresh is enabled. If it still disconnects, update your firmware — connection stability improves significantly in recent releases.
Can I use Bluetooth and USB at the same time on Ledger?
No. The Nano X and Stax operate in either Bluetooth mode or USB mode, not both simultaneously. Plugging in a USB cable will disable Bluetooth connectivity.
My Ledger doesn’t appear in the Bluetooth scan at all — why?
Make sure your Ledger is unlocked (PIN entered) and not connected to another device. A Ledger in Bluetooth mode will only appear as discoverable when it’s unlocked. Also confirm that Ledger Live has Bluetooth permissions on your phone.
Is Bluetooth safe to use with Ledger?
Yes. Ledger’s Bluetooth implementation only transmits encrypted, non-sensitive data. Your private keys never leave the Secure Element and are never transmitted over Bluetooth. The connection is end-to-end encrypted. That said, for high-value transactions, many users prefer USB simply for peace of mind.
Does the Ledger Nano S Plus have Bluetooth?
No. Only the Nano X and Ledger Stax have Bluetooth. The Nano S Plus is USB-only.
Bluetooth is connected but Ledger Live says “device not connected” — what do I do?
This usually means the app-level handshake failed even though the OS-level Bluetooth connection succeeded. Force-close Ledger Live, lock and unlock your Ledger, then reopen the app and try connecting again.
