Sometimes writing stuff down helps with thinking.

The error message is confusing, but I had forgotten to update the vlistfile after making changes to the variable definitions in Mervis.

It now works with integers. Seems to still have problems with strings though, is this a limitation?

I have successfully installed 'sscp-sql-bridge` and I can see that it is connecting to both the Unipi Windows RT on another computer and the MariaDB running on docker on a third machine.

I have made two simple tests: SELECT an INT value from the database, write it to a variable in the Mervis RT which is INT.

The integer value in the database is 1.
The bridge quits with the following message:

Writing variables bigger than 256 bytes is not supported!

If I try to read from Mervis RT and write to the DB (INT to INT again), I get the error message:

Reading variables bigger than 256 bytes is not supported!

It seems weird to me that an INT is bigger than 256 bytes, what is going on?
