Previous tutorials OK but this one produces error : (currently no ESP32 connected.)

Hi.
Which version of the eBook do you have? Check if you’re using the latest version V2.2.
Please check page 188. I recommend using Option number 2 or 3 at page 190 to fix the issue.
Let me know if this solves your problem.
Regards,
Sara

Later ….. The upload was successful but the IP address, 192.168.20.27, yielded “This page cant be found” both on Chrome Browser and Opera. But, I can PING the address OK from Windows10 CMD prompt.
Later, OK found the advice on p 187 and now I can get HELLO WORLD. Now ready to start 1.3 but not sure which I am going to settle on as I like both “Platforms”.
P.S. Yesterday I watched the SANTOS TOUR DOWN-UNDER on it’s way to Pt. Elliot. You must be proud to have your surname sharing history down here in sunny South Australia. Regards, Jim.

Hi.
The “This page cant be found” usually happens when you forget to upload the filesystem image.
You need to click on Upload Filesystem Image, otherwise the files will not upload to the board.
That’s great, thanks for sharing those news.

Sara
