Error compiling on Arduino Nano ESP32 - cannot convert USBCDC* to HardwareSerial*

1

Had this error building synman/BME280 for an Arduino Nano ESP32 on PlatformIO. lib/TelnetSpy/TelnetSpy.cpp:43:13: error: cannot convert 'USBCDC*' to 'HardwareSerial*' in assignment Google suggested this compile flag: platformio_options: board_build.extra_flags: - "-DARDUINO_USB_CDC_ON_BOOT=0"...

Allows use of this library with controllers that lack a distinct USB-to-UART chip such as the ESP32-S2

Do not store telnet pings in buffer. Tidier holdoff management
