"Error id 52: Unexpected server error." When uploading a Sketch in windows10

[RubensQRZ]

Dear Carlos, a new problem is occurring in the program when we send a code to the Arduio Board using windows 10. Maybe the consequence of some windows update.

The sketch is uploaded, but an error is displayed in the “Arduino IDE Autput”, with the message:

There has been an error Unexpected server error. Error id 52: Unexpected server error.

Even with this error, you can continue working and sending new sketches do the Arduino Board. But, after each load, the program shows the same error message.

This issue occurs with python 2.7.9 and python 3.4.4. I didn’t try with other versions. I have made tests in 2 different machines with windows 10-64.

No error message is displayed when we use the “Open Skecth in IDE” option. With this option everything works fine.

The error message displayed in the Python Shell is:

Uploading sketch to Arduino... CLI command: C:\Program Files (x86)\Arduino\arduino_debug.exe C:\Users\ruben\Downloads\ardublockly-master\ArdublocklySketch\ArdublocklySketch.ino --upload --port COM3 --board arduino:avr:mega Error: Exception in arduino_ide_send_code: 'unicodeescape' codec can't decode bytes in position 129-130: truncated \UXXXXXXXX escape

I made some tests and the error point seems to be here:

std_out = six.u(std_out) err_out = six.u(err_out)

The complete Python Shell messages follows below.

Thank you for your attention

best regards

Rubens.

After some tests I can see that the problem is with the Arduino Version. This issue does not ocurr if i use Arduino 1.6.11, but with Arduino 1.8.2 it occurs.

[puttley]

I am having the exact same issue. Can this be resolved? Is there a solution for using the latest Arduino 1.8.5 IDE with Ardublockly on Windows 10?

[axeede]

Same for me... Ardunio 1.8.9 with Ardublockly on WIndows 10 Ardublockly v0.1.2

[duinopeak]

Same for me...

The problem is the six.u method that does not work as expected. I changed my code to the following and it works now on all OS:

std_out, err_out = process.communicate()

# new conversion code not depending on six
std_out = std_out.decode("utf-8")
err_out = err_out.decode("utf-8")

exit_code = process.returncode
print('Arduino output:\n%s' % std_out)
print('Arduino Error output:\n%s' % err_out)

Have a look at the commit I've done in our respository: https://github.com/IAD-ZHDK/ardublockly/commit/a43797d348044234717b59996ba1d003ec4bf85f
