Which of the two connectors of the QN9080 are you using

—— I use J2 connector, the CMSIS-DAP interface can be recognised correctly;

 have you installed the SDK of the QN9080? Which example are you using

—— I have already installed the sdk, version SDK_2.2.0_QN908XCDK,I have tried some of the driver examples, I can debug them normally, but the vcom interface can not be used all of them.

Thanks.

Hello, 

Could you please try changing the interface to J-Link? Just to make sure it is not due to the current interface.
