I am getting this as error return from the "ref comp" command.
Nextion instructions page does not list this number in a code description.
Since it is returned nevertheless, the developer surely knows what it means...
can you let me know please?

I deducted from the messages exchange between my Mega2560 and Nextion that this code 0x02 returned from Nextion means the "ref compID" command refreshed the component which was in the page which was not active at the moment.
