Firmware works without any issues on my NodeMCU (ESP12E), but settings are not saved correctly on my ESP-07. My assumption is that the different flash size is the culprit even though 1MB should be enough.
I am having the same issue on the "mRo WiFi Module V1.0 - ESP8266". Setup everything on the web interface, hit save, then reboot. Upon reboot, the settings are back to defaults.
