Sparki invisible for PC

Hi everyone,

I have a problem with my Sparki. When I plug in the robot, PC can idintify Sparky only during STATUS led blinking.

After that Sparki become invisible.:pensive:

Please help me whith this problem.

Hi! I had similar weirdness when I had a program flashed that wrote to the serial port from sparki. The bytes that sparki would send to the serial port would interfere with the communication that the Arduino interface has. I had to carefully reflash ( sort of a “cold flash” using the reset button, described well on the Sparki website ) a program which did not write to the serial port at all ( like most of the examples ), and my problem went away.

Hope that helps you! Good luck!

When you say “cold flash” do you mean when you hold the reset button while uploading the code? I’m having an error with 30+ sparki’s where they refuse to stay on the same COM port. Either they just aren’t detected or when the upload code button is pressed the Sparki almost immediately changes its COM Port.
