@watson Hello Watson, I did all you asked and it still doesn't work.0_1537997574614_Screen Shot 2018-09-26 at 5.20.59 PM.png.

The COM port is open and selected. When I try the hello world sketch I get the following error:

A fatal error occurred: Invalid head of packet ('5')
A fatal error occurred: Invalid head of packet ('5')

Thanks for any help.
