Hi, im trying to get a serial connection going from the esp to this device https://www.me-systeme.de/shop/en/elect ... t/gsv-3usb. I managed to get a connection but im not sure where to go from there. After connecting with i get the following device information:
both
fail so i guess thats not supported.
How can i get a serial connection with 38400 baud and 8n1? Am i even on the right track with CDC?

The data im getting in the handle_rx callback looks like this:
while a working connection should put out something like this:
