The device can be found through Windows ->Settings ->Bluetooth and other devices ->Add Bluetooth and other devices, but it cannot be connected normally, and the prompt is that the Bluetooth service cannot be found

Hi, 

Are you able to test with nRF Connect mobile app? Does it also have the same situation? Could you provide the log from the app?

What is the debug log on the device?

It would be helpful to know what happen in the air if you could provide the sniffer log. 

Which SDK are you using?

Regards,
Amand H.
