TcpUpdate Error

[SeeCwriter]

At the completion of programming a Nano module using Autoupdate, v2.5, the following message is output on the serial port:

TcpUpdate Error: 40

The module is programmed correctly and runs as expected. I have detected nothing wrong. What does that message mean?

The applications are built with v2.9.5 of the tools.

I don't see the string "TcpUpdate Error:" anywhere in our code. Is that something in your app?

Well, this is embarrassing. It is in my code. It's generated when function StartTcpUpdate returns a non-zero value, which in this case is 40.
