Problem Uploading sketch [error: espcomm_open failed]
Posted: Thu Oct 05, 2017 1:00 amHi!
I'm running Arduino IDE 1.6.8 in a Macbook with Mac OSX El Capitan 10.11.6, and a Wemos D1 mini board and I'm getting these errors when trying to upload a basic sketch:
This is how my tools config looks like:
When I click upload, I see the serial led in the board blinking for a few seconds, and then I have this error.
I'm new to this board, do I need to connect something? I have nothing connected to the D1 mini board, I have 2 new boards and trying with both I have the same Issue , I've also tried with differents USB cables.
Please help! Thanks!
