Thank you for your reply.
It seems the issue didn't occur on the specific bluetooth devices.
Could you please update bios 413 and check bluetooth again?
If it still does not connect the connected devices and does not see new ones, could you please record a video, backup your personal data and reset the system to check it again?
Thank you so much.
We didn't receive the same feedback from other customers and our tech team have tested bluetooth on bios 413 but didn't encounter the issue you mentioned.
Here is the test video by our tech team. I'm sorry the setting language is Chinese.(å·²é€£ç·š means connected)
