Manage your XNote Smart Pen's configuration and perform advanced operations.
How to access: You can reach Pen Settings in two ways:
- From the Home screen: Tap the Pen Status Badge when your pen is connected (the blue settings gear icon). (See 2.5.1).
- From Settings: Go to Settings -> Pen Settings.
Note: Pen Settings are only available when the pen is connected via Bluetooth.
2.8.1 Pen Settings
The Pen Settings screen allows you to configure the following:
- Auto Power-Off : Set the idle time before pen turns off (1-10 hours).
- Pen Sound : Toggle the pen's sound on or off.
- Color Picker : Show or hide the color picker in the writing interface.
- PIN lock: Add a 4-digit PIN to prevent the pen from pairing with other devices.
- Mirror Writing : For left-handed users who write in reverse (see details below).
- Device Info : View MAC address, model number, battery level, and firmware version.
- Disconnect Device : Disconnect the pen from the app.
PIN Lock
When multiple pens are open in the same location — office, classroom, meeting room — phones could select the wrong pen during connection, and notes could end up in another account. PIN Lock prevents this; to connect a pen to an account, you need to enter the 4-digit code for that pen. Even if the pen is nearby and appears in the connection list, it will not connect to any account without entering the PIN.
You can set or change the PIN from the pen settings. When you change the PIN, other devices connected to the pen will be prompted for the new code.
After setting the PIN, you choose one of two behaviors:
Remember on this device: The phone keeps a copy of the PIN in its secure vault. It will not be asked again on this phone.
Ask on every connection: No copy is kept on the phone. The PIN will be requested again on every connection.
In both cases, the PIN is stored on the pen, not in your account. Therefore, the PIN will be requested again when you use the pen on another phone or on the web.
Important:
If you forget your PIN, it cannot be recovered. The only way is to reset the pen to factory settings, and this will delete any untransferred notes on the pen (see 2.7.2).
After 10 incorrect PIN attempts, the pen automatically resets to factory settings, deleting any untransferred notes on the pen. Keep count of your attempts before guessing repeatedly.
Resetting does not remove the pen from your account. If you are selling or transferring the pen, you will also need to perform the "Remove pen from account" operation.
Multiple pens may be listed on the connection screen. Make sure you select the correct pen; if you try to enter the PIN for the wrong pen, the connection will be rejected.
Mirror Writing
This setting is designed for left-handed users who naturally write in reverse (from right to left), producing mirror-image handwriting. When enabled, the canvas is flipped horizontally so you can write from right to left naturally, and XNote's OCR engine will correctly interpret your reversed handwriting.
When you toggle Mirror Writing:
- Enabling: A confirmation dialog appears explaining that the canvas will be flipped horizontally. If you write normally (left to right), do NOT enable this it will cause incorrect text recognition results.
- Disabling: A confirmation dialog explains that the canvas will return to normal orientation.
Important:
- Mirror Writing is independent from the Handedness setting (see 2.2 Step 3). Being left-handed does not automatically mean you use mirror writing. Most left-handed users write normally and do not need this setting.
- Only enable this if you actually write in reverse (mirror image). Enabling it with normal handwriting will produce incorrect OCR text.
- This setting affects how your handwriting is displayed on the canvas and how it is processed for text recognition. It does not modify your saved stroke data.
2.8.2 Factory Reset
Factory Reset completely resets your XNote Smart Pen to its original factory settings. This erases all pen data and settings permanently. Your account, notebooks, and synced notes in the app are not affected.
Step 1 : Open Service Menu
Go to Pen Settings (see above). Tap the MAC address field 5 times to unlock the hidden Service Menu.
Step 2 : Tap Factory Reset
In the Service Menu, tap the "Factory Reset" button. This button is only available when the pen is connected.
Step 3 : First Confirmation
A warning dialog will appear:
"This will completely reset your pen to factory settings. All pen data and settings will be lost. This action cannot be undone."
Tap "Factory Reset" to proceed.
Step 4 : Second Confirmation
A second dialog will ask:
"Are you absolutely sure? This will erase all pen data permanently."
Tap "Reset Now" to confirm.
Step 5 : Reset Complete
Once the reset is finished, a success message will appear. The pen will be disconnected from the app and returned to factory state. You can re-pair it via Bluetooth (see 2.3).
