Why is there no sound after successful Bluetooth connection?

[StJune]

Reasons for no sound after successful Bluetooth connection: 1. The wireless network distance is too far, resulting in poor signal reception; 2. Insufficient battery power or poor battery quality causing low voltage; 3. Incompatibility between the phone system and car Bluetooth system; 4. Bluetooth headset malfunction. Solutions: 1. Disconnect the WIFI signal on the phone and try reconnecting; 2. Disconnect the device, reduce the distance and re-match the signal; 3. Charge the Bluetooth device or replace the battery; 4. Connect the phone to another Bluetooth device. If the problem doesn't occur, it's an issue with the car Bluetooth system which needs repair. Bluetooth technology is a global standard for wireless data and voice communication, based on low-cost short-range wireless connections, creating a special short-range wireless technology connection for establishing communication environments between fixed and mobile devices.
