I thought the ESP-12 was to be flashed as a 4M flash size.

On a side note this has been identified as a bug. It will be fixed with the new version. I am running the build right now and it should be uploaded in a couple of minuets.

memclear will erase all of the variables in memory and is probably not the right approach. The program will read the correct file this time.

Re 'memclear' ... I didn't see mention of this in the docs. Must have missed it ... or perhaps it's a standard BASIC thing that I'm not used to (my knowledge of BASIC is very old and tired).

It certainly sorts the problem that I was seeing.

What exactly does 'memclear' do? Does it have any side-effects on other variables?
