I changed my definition as above:
{$M+}
TEspConfiguration = Class(TObject) //object
published
checksum: word;
ssid: AnsiString;
passwd: AnsiString;
macaddr: AnsiString;
addr: TIpAddress;
baud: integer;
....
end;
but then when I compile I get this error (14 times):
wificommhandler.pas(81,5) Error: Symbol cannot be published, can be
only a class
Do I need to declare the fields as private first so they can later be
declared published?
Or are these fields (simple variables and ansistrings) incompatible
with the fpc JSON handling? (Must be a class...)
Maybe it is simpler after all to code this without using fpcjson.
The JSON structure is not that complicated to handle, especially for
writing....
