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.

SCID
Source Channel Identifier. Used in the L2CAP layer to indicate the channel
endpoint on the device sending the L2CAP message. It is a device local name
only.


DCID
Destination Channel Identifier, used as the device local end point for an 
L2CAP transmission. It represents the channel endpoint on the device 
receiving the message. It is a device local name only. See also SCID.
