Unfortunately, it is still not working for me, I tried a couple of different things people suggested for flashing the core, but I believe that it is failing with the CLI tools, and I’m still getting the “Cannot initialize ESP-AT Lib!” even with the WiFiClientSecure library. I have no way at this point to connect - it is very frustrating, and walking away from the problem didn’t seem to help me 
Maybe someone can post the windows 10 GUI tool somewhere and I can try it, I can’t seem to locate that anywhere either. All in all very frustrating.
Thanks - LeRoy
