  • Thank you for your quick response.

    Maybe I didn't express clearly, I mean caught this uncommunicable connection packet.

    In this case, I do not disconnect the app, and use nrfconnect to connect, and the service characteristic value can be found.

    personally I think that there is a problem on the app side, but we cannot tolerate such a connection, can the slave know this and then disconnect?

    Thank you
