Yes, but you wrote that you were doing this in cCiTransportConnection::Data(), where
there is no such test at all. I assume you actually did this in
cCiTransportConnection::CreateConnection(), which is right _below_ the Data() function.
That would explain why it sends the [00 01 82 01 01] repeatedly with your changes.

However, I suggest the implementation I have uploaded should be better (even though
it doesn't fix the problem).

That's possible - but in that case it would probably mean that there is
something wrong in the driver/firmware with the "Link Layer" protocol.

Let me know if you find something.
