修复蓝牙连接问题
按照以下故障排除步骤,解决各种设备上常见的蓝牙配对、音频和连接问题。
Check Bluetooth is enabled
Open Settings > Bluetooth and verify the toggle is ON. On Windows, also check the Action Center quick toggle.
Put device in pairing mode
Most devices: hold the power or pairing button for 3-5 seconds until the LED flashes. Check your device manual.
Remove old pairings
Delete the device from Bluetooth settings on both your computer and the device, then re-pair from scratch.
Restart Bluetooth service
Toggle Bluetooth off, wait 10 seconds, then turn it back on. On Windows, restart Bluetooth Support Service.

Check for interference
Move away from WiFi routers, USB 3.0 devices, and microwaves. These operate on similar frequencies.
