Error using esp32 with ros_serial

edit

HI All

Im trying to get my esp32 to publish to a ros topic… Im looking for the simplest way to do this…

I followed

http://wiki.ros.org/rosserial_arduino...

I think i have setup the IDE correctly, when i run the hello world example

http://wiki.ros.org/rosserial_arduino...

When uploading the scetch i get
