ARDUINO IDE DOSEN'T RECOGNIZE ESP32 PORT

[Rjp663]

Hello,

I'm seeing an error with the Arduino IDE version 1.8.5 recognizing any serial port when a Feather ESP32 is connected.

I'm a Mac user, running OSMac 10.13.6 High Sierra. All current patches installed.

A few troubleshooting facts.
1. Several ESP32s exhibit the same failure. All were tested without addition feather-wings/circuitry connected.
2.Multiple USB cables were used and verified good.
3. All Arduino Libraries are current revisions.
4. Different Macs were used.

Interesting clue, my SERIAL interface program can see the port connected to the ESP32, but not the Arduino IDE.

Any help would be appreciated.

Additional progress. The Silicon Labs Driver isn't loading onto my OS.

I've determined this by opening a terminal window on my MAC and running the command:

ls /dev/tty.*

The USB to UART adapter isn't listed. Darn!

So the question is who is at fault APPLE or Silicon Labs???

Resolved:

As macOS High Sierra 10.13 introduces a new feature that requires user approval before loading new third-party kernel extensions, referring to Apple Technical Note TN2459:

https://developer.apple.com/library/con ... index.html

When you download the Mac OSX CP210x VCP driver v5 from the Silicon Labs website, approve the CP210x driver by clicking "Allow" in the Security & Privacy System Preferences panel as TN2459 mentioned to complete the installation of the driver.

Enjoy,
Rick
