Yes, it does a bit more, but, you should make this more explicit.

Have a real error be returned by the function, and then have the caller
handle the error by propagating it back to the firmware through the
message.  That might save you a lot of boiler-plate error handling logic
as well, right?

That will make it obvious that if an error happens, it is caught, and
how it is handled correctly.

Does that help?
