Bluetooth, protocol, SCID, DCID.

Hi All, My problem:



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


  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, Boki.
