1. Why is it necessary to authorize WeChat Bluetooth permissions?
Bluetooth permissions control the ability of applications to access Bluetooth devices on the mobile system. WeChat needs to call Bluetooth when using the following features:
- Connecting to smart hardware: such as smartwatches, Bluetooth headsets, in-car systems, etc.
- Voice call transmission: answering WeChat voice or video calls through Bluetooth devices.
- Nearby device interaction: such as WeChat’s “Shake” feature or certain mini-programs that require searching for nearby devices.If Bluetooth permissions are not authorized, WeChat will be unable to scan or connect to Bluetooth devices, resulting in the failure of related functions.
2. Android System: Complete WeChat Bluetooth Authorization in Five Steps
1. Check system version and basic settings
Android 6.0 (Marshmallow) and above support more granular permission management. Before proceeding, please ensure:
- Bluetooth on the phone is turned on (pull down the notification bar and click the Bluetooth icon).
- WeChat is updated to the latest version (to avoid compatibility issues).
2. Enter the permission management interface
Path One (General Android System):
- Open “Settings” → Select “Apps & Notifications” → Click “App Management”.
- Find “WeChat” in the app list → Enter the “Permissions” option.
Path Two (Huawei EMUI/HarmonyOS):
- Open “Settings” → Select “Apps & Services” → Click “Permission Management”.
- Find “WeChat” under the “Apps” tab.
3. Authorize Bluetooth permissions
In the WeChat permission list, find the “Bluetooth” or “Nearby Devices” option, and select “Allow” or “Always Allow”.Note: Some Android systems categorize Bluetooth permissions under “Location Information”, so “Location Permissions” must also be enabled (as Bluetooth scanning may involve location functions).
4. Verify authorization results
Return to WeChat and try to connect to a Bluetooth device (such as a headset); if successful, the authorization is complete. If you still cannot connect, you can try:
- Restarting WeChat or the phone.
- Clearing WeChat cache (Settings → App Management → WeChat → Storage → Clear Cache).
3. iOS System: Four Steps to Enable WeChat Bluetooth Permissions
1. Enter system privacy settings
The iOS system has a more unified management of Bluetooth permissions, with the following operation path:
- Open “Settings” → Scroll down to find “Privacy & Security” → Select “Bluetooth”.
2. Authorize WeChat to use Bluetooth
In the Bluetooth permission list, find “WeChat” and turn on the switch on the right.Tip: iOS 13 and above support more granular permission control, allowing you to set WeChat to access Bluetooth only while in use.
3. Handling special scenarios
If WeChat voice calls cannot output sound through Bluetooth devices, additional operations are required:
- Open WeChat “Me” → “Settings” → “General” → Enable “Receiver Mode”.
- Ensure the Bluetooth device is successfully paired with the phone (Settings → Bluetooth → Device list shows connected).
4. Compatibility verification
iOS users should pay attention to the compatibility of WeChat version and system version. For example, WeChat version 8.0.30 and above supports deep Bluetooth interaction with iOS 16.
4. Frequently Asked Questions
Q1: What if I still cannot connect to Bluetooth devices after authorization?
- Check device distance: The effective range of Bluetooth is usually within 10 meters and without obstacles.
- Restart devices: Restart the phone and Bluetooth devices to clear temporary faults.
- Update firmware: Some Bluetooth devices need to upgrade firmware through the official app.
