I saw some similar question,the answer is reader can’t connet in debug mode.
I use ‘flutter build apk --release’ to build apk,but it’s also connect failed.Should I add some other code in my project?
I try both 2.0.2 and 2.1.0 version,the result is same.And I had already set sha256 successful in the dashboard.
In Android13 device, I use the same apk, the reader status can be ‘Ready’.

That is correct, a reader isn’t able to connect when in debug mode. 
I didn’t open the develop mode,and I use the release apk with signature.why it’s still fail to connect?Where can I get the detail log?
What’s your application ID?
