Filesystem problem - lack of memory SPIFF ?
Posted: Thu Aug 11, 2016 11:36 amI have trying to program ESP8266-1 in lua for a few days, so it could be problem that I'm doing something wrong. I have written simple program to test files.
Idea was to get as much data as I could from sensor. It mean that I was going to write data to file, and when filesystem would be full delete oldest file.
after several runs (about 340) my module hangs, reset with reset code 2 !!! what was impossible. Reset pin pulled.
module doesn't respond to Esplorer even when I try to change lua file
but after format module work OK.
Question is if there is a bug or am I doing sth wrong
my module ESP8266-1,
there is my code
Best regards

But that shouldn't render the file system unusable.
