Connection between UI and bot

[vuhuyhop197]

When I start Spherebot_UI.exe. I can connect successfully to the bot. But I can't send or receive any message. May I need to install more library? Please help me. Thank you very much!

If you can start the application without any errors then all libraries are there.

Please make sure you use the same baud rate on your firmware and on your UI.
Without any details this is all I can tell you.

I've the same issue as @vuhuyhop197
Everything seems to work but when I try to send a .gcode file to my board with this Software nothing happens. It's said "sending file" with a progression bar staying at 0%

To make my Spherebot I followed the project from this website : https://www.open-electronics.org/spherebot-reloaded-customize-your-xmas/
First I tried with the firmware they gave, then with yours but result is the same.

I would be very thankful if you've any idea or solution to my problem.

The Spherebot UI waits for the spherebot to acknowledge each line with an ok
if this is not received then it won't send the next line.

You could try a serial terminal to send manual commands and see if they work.
If not then something is wrong with your Arduino/Firmware/Wiring.
