sense.py doesn't show accelerometer during execution but when disconnecting micro:bit #1

The sense.py is working for the buttons, A and B are displayed on the micro:bit. No values are printed on the console from where I launched the script. If I disconnect the micro:bit, all the print statements appears (and then the SerialException which is right)

I've done this with python 3.6.1 on Windows in Git Shell

oh, that's odd.

I just tried this in python 2 and python 3 and I get this output:

I forgot to add a step to the install instructions for windows - do you have the mbed serial driver installed?

I've yet to test this library thoroughly on all platforms and haven't had a chance to test on windows yet. I will try next week.

What version of windows are you using?

Also, can you check if you have a pyserial in your distpackages?

e.g. if you just run

python3

from the shell and then

import serial

then

print(serial.VERSION)

what do you get?

I have packaged a version of pyserial 3.3 in the microbit folder and the hope is that it imports that, but I may have to add some extra logic to force it to import that if you already have a pyserial in your distpackages - there are various incompatible changes between each version of pyserial, and I'm trying to force this to use a specific version (i.e. a version I have already tested against).

So first, it's not a major issue as I used Windows just because I was just coming from a game with my son. But still, as I have this Windows box, I can do tests before booting back to my beloved Ubuntu ;) In order: 1) I have mbed driver, I already used it for Mu editor 2) output => 3.3 If you want me to do other operations, just ask, it will be my contribution to this lovely project.

As I had a very small test programm to exchange between micro:bit and PC I tried it. And it failed the same way : nothing and as soon as I interrupt, all print statement result appears.

As I mentionned, I worked in Git shell which is not the normal command line. So I launched my script then yours and everything worked as expected.

The conclusion is we need to use the official command line for serial interactions. That being said, I boot back to Ubuntu ;)

Ok, thanks for the update! At least if anyone else uses this in gitshell this issue will help them understand what the problem is. Thanks for trying it!
