Connect with the mobile app over Bluetooth

DCENT X connects to the DCENT mobile app over Bluetooth (BLE) as soon as you scan the QR code shown on its screen with the app. If you've connected before, you can reconnect by simply tapping the Bluetooth icon in the app. The steps below are the same on both Android and iPhone (iOS).

info

On Android, you can also connect DCENT X directly with a USB cable instead of Bluetooth. See Connect with a USB cable for details.

Before you start

To connect DCENT X, first install the DCENT mobile app on your phone and allow the Bluetooth (and Camera, for QR scanning) permissions the app requests when it launches.

info

The official app name and store link will be added once the app release details are confirmed.

Basic setup for the mobile app

If you just installed the mobile app, set the wallet mode and grant permissions before connecting the device.

Select the wallet mode

Launch the DCENT app and, on the wallet selection screen, choose "Biometric Wallet" (connect a fingerprint wallet over Bluetooth). DCENT X is a biometric wallet that connects over Bluetooth.

Wallet mode selection screen

Set app permissions

The app shows which permissions it requests. Bluetooth is a required permission for connecting to DCENT X over BLE to view accounts, sign, and more. Review the notice and tap "Confirm", then tap "Allow" on the Notifications and find Bluetooth devices permission popups that follow.

info

The screens above are from iPhone (iOS). The flow is the same on Android; only the nearby-device (location) permission popup for Bluetooth looks different.

Connecting during initial setup

When you power on a newly purchased DCENT X and select a language, the app connection screen appears. Connecting the app here lets authenticity verification and account syncing continue right away.

Step 1 — Select "Connect" on the device

On the DCENT X screen, select Connect. You can choose "Set up without connecting" to proceed without the app, but connecting is recommended for authenticity verification and account management.

Step 4 — Verify the pairing code and allow

Check that the Approve code on the DCENT X screen matches the code in the Bluetooth pairing request popup on your phone, then tap Pair on the phone and select Approve on DCENT X.

Troubleshooting pairing issues

The QR code doesn't appear

If the screen didn't switch to the QR code view, open the Control Center and check the color of the Bluetooth button. If it's dark gray, Bluetooth is off. Tap it to turn it on, which switches to the QR code screen for connecting.

Control Center - Bluetooth button

The connection drops

If the connection drops, the Bluetooth button in the Control Center turns dark gray again. Tap it to turn Bluetooth off, then tap it again to turn it back on — a new QR code appears, and scanning it from the mobile app reconnects the devices.

If Bluetooth disconnects during initial setup, the app shows a "DCENT X has been disconnected" screen. Tap Reconnect to reconnect Bluetooth, and the process resumes automatically with no further action needed.
