ESP8266 Community Forum

Hi all!

I'm uploading new firmware to the ESP8266 with Arduino Core via OTA ( Web Browser example ): http://esp8266.github.io/Arduino/versio ... dates.html

Question: is the updating process guaranteed in some ways? I mean, is the new uploaded file checked after the process, or is there integrity on transferred data? Is an 100% secure process?

Hope my question is clear

Thanks

ArduinoOTA rely on Updater class which rely on MD5 if the server provide it.
So, if there is an MD5 error while doing the OTA, the current old firmware will stay the active one until a new OTA is performed.

Hi martinayotte,

thank you for your reply.

Is it only valid for the OTA via Arduino IDE, or also for the WebServer and HTTP Server example?
Thanks

You can check if there is a call to Update.setMD5() ...
