Ongoing development: issues and findings

[bertmelis]

I'm using this issue to track my findings and issues. If you encounter any roadblocks, feel free to add to the topic.

My setup will be a Lolin S3 mini connected to an ftdi board. This board will be connected (UART side) to another ftdi board plugged into my laptop. All boards are powered by the usb board in the laptop.

Software will be Termite (Windows) and a simple USB<>MQTT forwarder.

develop has now working code. Tested using platformio.

I'm using an ESP32-S3 and set these options

build_flags=
  ; following lines prevent the USB interface to be taken by 'Serial'
  -D ARDUINO_USB_MODE=0
  -D ARDUINO_USB_CDC_ON_BOOT=0

Depending on your hardware, you have to disable global hardwareserial objects altogether because these might interfere with the USB data lines.

When disconnecting the USB device, the ESP crashes. It's on the to do list but because I never do this, this is not my immediate priority.
