Windows 10 Error: could not open port '\\\\.\\BLE': FileNotFoundError

Hi!

I am really interested in this utility. It should be very useful. I try ble-serial on win10, but fail. Why?

Please help me… Thank you!

Great, it took effect after disable the secure boot option. I also missed this note. I thought it was not relevant. When I changed the settings from the BIOS, everything was normal. @cjgu00 @Jakeler Thanks a million!

Hi!

Finally, I found why I failed on the 1st computer but succeeded on the 2nd one! The 1st computer is a pretty new one of my friend. I missed the following note because I had no idea what is ‘secure boot’. Maybe some words about that could be helpful for newbies like me.

After fixed, the new computer could run normally.

The 2nd computer is my old computer. It didn’t have ‘secure boot’ option. So it could run without changing any settings.

Hope this can help!
