Hello @zhangxy

@xiong.zhang @william.lin will help you then.

Hello, what is the firmware version you use

I buy it on taobao https://item.taobao.com/item.htm?id=607784134524, how can I confirm the firmware version

Just find an About to view in the settings

I verified this version of the firmware locally. Music or videos can be played normally after connecting to a Bluetooth headset. Have you connected the antenna?

Music can play through bluetooth headset after connected the antenna. thanks
