Hi 

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.

 

Thanks

Hello @jeje_2937166 

Are you using our default RFCOMM serial port example available in MTB  ?

which mobile phone or application did you tried ? Have you tried on any other peer devices ?   

Can you please share the complete log so that we can check the issue ? 

Regards,

Anjana
