It is not connecting or connecting.
I have been stuck here for a week.

Hello,

Thank you for confirming the SDK and version. Have you followed all the steps in the guide I mentioned? Please also take a look at this sample application. Check the testing section to see if you can perform a buttonless DFU.

I recommend providing more details about the issue you’re facing, such as logs or error messages.

Kind Regards,
