Basic Assembly and Setup

I had serious difficulties to upload the firmware (the upload got into an infinite loop with the question "Reset joint offset?" (both the Petoi Desktop and the Arduino IDE). Finally, I managed to resolve the issues (but don´t know how). A few days later I connected a HCSR 05 ultrasonic sensor and tested it (it worked). I decided to recalibrate the robot, but the calibration did not work. I re-loaded the firmware and since the same "Reset joint offset" loop have been occuring.

If I quit and start the calibration there is an error message

re ['c\r\n', '']

of

Exception in Tkinter callback

Traceback (most recent call last):

If I comment out the Main Sketch, the desktop Petoi App does not recognize the connected board. Also, a very bright blue led is on (I don t remember seeing it before..).
