Hi,

Is it possible to perform an OTA upgrade using the ESP8266-07? I've tried a lot of tests with no luck and I've seen this posthttps://github.com/esp8266/Arduino/issues/1092.

Furthermore, I am not able to get an english datasheet of the ESP-07 or ESP-12 to compare the memory of each chip.

Thanks,

A.

Hi tlerdrden,

I would check the flash size using https://github.com/esp8266/Arduino/blob ... Config.ino

I am also curios what flash size it will show for your ESP-07

Hi Kzysztof!!

Thanks for your help, this is what I see through the Serial port:



What do you think?

Hi tlerdrden,

Basing on the output on serial port - Flash real size: 524288 / 1024 = 512K flash

What is the size of your sketch? Does it meet Basic Requirements - https://github.com/esp8266/Arduino/blob ... quirements ?

512K flash it usually not enough even for a simple sketch with OTA routines.
