There is a LUA virtual machine in it. RAM consuming, a bad "feature".

The situation is much better by saving the LUA file in the flash memory and calling it with dofile(filename).

Are there more hints and tricks to save the precious RAM?

I'm a newbie to Lua too.
the only trick I know, delete a object by assign it a nil value if it is not needed any more.

Code: Select allcon=net.createConnection(net.TCP)
--some work to do
--everything done
con:close()
con=nil   -- this will save some ram.

Thanks!
