Hi.
You copied the URL wrong.
This is the right URL:
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
You must have deleted a “-” without noticing.
Let me know if this fixes the issue.
Regards,
Sara
Thanks Sara. Now it is OK. Should not used OCR to get the URL from the book. // Anders
