Tonight I tried out your latest version of the dropcontroller 2019_V3_003.
After downloading the sketch in the Arduino micro I still wasn’t able to connect with the windows app.
I decided to dive into the VB source files that you made available.
I’m totally not experienced with programing in VB but after looking to this video https://www.youtube.com/watch?v=xRfQGd5nLfo i was thinking to give it a try.
In the video you can see the settings of how the serial port is configured (around minute 8). I configured the serial port in your application exactly like it was done in the video the only exception was the COM port which I changed to the COM port that my Arduino micro is connected (In my case COM3) and after compiling and creating an exe.
TADA I was now able to connect with the Arduino micro and send commands from the windows app to the dropcontroller.
I can’t hardly wait till my missing parts are arriving from amazon so that i can start building and serious testing.
Can you please check this out if this work with the nano as well ?
