During the SPP test, the ACL was connected, but the RFCOMM was not connected.
Looking at the mobile phone BT_Snoop.log and Air Log, SDP Search/Attrib Req is transmitted from the mobile phone,
and then the response is transmitted from cyw20706.
I think smart phone can't get it due to problems such as RF
But For other chips, SDP Search/Attrib RES transmutted several times.
Why is it different from other chips?
Tell me the transmission sequence of Res and how to transmit it more than twice.
