The witty uses a CH34x USB/serial chipset which macOS High Sierra (10.13) and earlier doesn’t have a native driver for. As the version of macOS used does not include a driver for the “Witty” module’s interface adapter a third-party driver was installed.Device driver for the witty’s interface Python 3 was installed and a Python “venv” virtual environment was created to contain the python libraries used by esptool. This is a walkthrough of how I installed the Python-based esp8266/esp32 serial bootloader utility esptool on my Apple iMac – a 27-inch, Mid 2011 running macOS High Sierra – and used it to program an ESP8266 “Witty” module with esp8266/Basic. You can visit my blog for the complete Windows, Mac OS X and Linux instructions Previous AT versions were based on the ESP8266 NONOS SDK, to which no new features will be added in the future. When developing new products with ESP8266, it is recommended that you use ESP8266 AT Bin V2.0.0.0 and/or later versions. Apples driver and oem drivers conflicting. Catalina has ch340 drivers already and I setup oem driver from GitHub. Are there any solution about this problem? EDIT: I fixed issue last night. I tried some serial monitors, Arduino IDE and platform io ide but still same. *I can see hello world on serial monitor. Double click on Silicon Labs VCP Driver Install Disk.pkg.

These are a driver that can communicate to that little square chip (CP210x USB to UART Bridge VCP) we mentioned before: Download it to your Downloads folder.

The first step on the mac is to install drivers.
