I just ran into a problem while trying to use PlatformIO to program a WeMos D1 R2 Board for an Exam of my University:
PlatformIO does not automatically recognize my USB Port while trying to upload code to the board. And after manually configuring it on my Linux Mint (PlatformIO.ini -> upload_port = /dev/ttyUSB0 ) i get the error : cannot access /dev/ttyUSB0. I already added my user account to the dialout group to get root access on the usb port,but i still get the same Error, no matter how often i try.
I would be glad if somebody could help me out
P.S. If i check the Serial Monitor Option under the “PlatformIO” Tab in the top menu, i dont get any options to select for the port
