RFCOMM DLCI and Credits

123music

Hi,

I have a small technical doubt regarding DLCI in rfcomm.

While opening rfcomm channel when does it fails to open DLCI? What are the possible reasons for DLCI failure?

Also during parameter negotiation, what exactly credits mean. I am little confused about credits in rfcomm.

Please clarify.

Thanks.

Hello 123music,

Which BT stack is giving you the DLCI failure?

Regarding the credits in RFCOMM, it is no more than a flow control mechanism for the RFCOMM data.
