Can you share your example lua files?

Sure. See attachment. But it's just quick and dirty LUA testing

Yes, this is a shortcoming of most upload tools: They all use [[]] to send a line which causes problems when this long bracket string notation is used in the Lua program.

You can use my 'uploader.py' Python script which does not have this restriction (and which is also orders of magnitude faster than the other delay-based upload tools): viewtopic.php?f=22&t=1026

Alternatively, you can modify the long bracket [[...]] notation of level 0 to something like [=[...]=] or [==[...]==] (long bracket notation of level 1 or higher). http://www.lua.org/manual/5.1/manual.html Section 2.1

downloaded code ( see prior post) from Markus Gritsch ( file renamed to \server_GPIO0_LED_get.lua) but it has issues so I don't see how it proves that a single send resolves the fact the sever doesn't work with the latest release yet the same code works with earlier releases.
Further sending a full html form via a single send probably may have new issues like max packet length of 1460 being exceeded.
