Same here, manual using ftdi works just fine, but using the Pro Mini gives me nothing back from the serial connection like described in your 1st post.

*EDIT: @maptor , solved my problem. Arduino board type was wrong when uploading and powersupply to esp was too much. It's just not stable enough.

- Sat Feb 27, 2016 2:40 pm #42016 Hello,
I've tested the 256 Buffer size without success:

sketch/sketch_sendTemp.ino.cpp:1:21: fatal error: Arduino.h: No such file or directory
#include <Arduino.h>
^
compilation terminated.
exit status 1

I still have the same problem: the serial monitor prints a well formed string, but when I use readString() or read(), the string is corrupted.
Is there an issue to this problem ?
