Yep, an update about the updater... :)
As you can see, when doing an OTA update of an ESP8266, it is now grabbing the response from the ESP module to confirm that the update was received correctly, and the module is rebooting... Same response you see when you use a browser.
All in all, not bad for a days work considering I haven't used C# in over 5 years.
Surprisingly switching between C# and C++ has been seamless...
