    Hi All,
    My problem:

    I am dealing with a Bluetooth device connection problem. I save log file by
    I found there is a different between connection success and connection fail

    1. SCID.
    2. DCID.

    I can't sure these two item are important to connection or not, but I can
    only find these right now.

    Otherwise, I can't explain why my master device request "Disconnect"( I want
    to it keep the connection), I don't know the reason, after that request,
    the salve accpet this request (Disconnect), but the bluetooth connection
    still exist, but after that time, I can only receive bad payload.

    Is that the bluetooth firmware/driver problem?

    Please advice any comment.
    Best regards,
