I ordered a number of ESP-07S units from China and now I have received them.
Will be used for some home surveillance projects.
Questions:
- How can I find out what is the flash size of this module? I think it is 4 Mbytes but I am not sure.
- How can I back up the AiThinker firmware?
The module responds to AT commands and I have tested this:
AT+GMR
AT version:1.2.0.0(Jul 1 2016 20:04:45)
SDK version:1.5.4.1(39cb9a32)

OK
So it is about 16 months old firmware.
I want to load a test sketch but then the supplied firmware will be erased so before that I want to back up the existing firmware.
I have found some flash tools like esptool.py, but this does not work on my Windows 7 PC.
I think it is only for Linux...
