Scroll hello, world shows only "hello". I discovered this bug when I read the source code of s2mb.py. One way to solve this is to scroll from the original string.
I changed the code on line 99-101 to:

        # scroll text command
        elif cmd_id == 's':
            display.scroll(cmd[2:], wait=False)

Hi, Alan,
According to your experience, do you think is feasible to use Scratch to send and receive radio command to/from another micro:bit in a properly way, as BLE is not available in micropython?)

In this way should be possible to:

• Scratch + usb connected micro:bit to control a remote micro:bit

• Remote micro:bit to send command - to an usb connected micro:bit + Scratch - like (button A pressed, button B pressed , tilt up, tilt down, right, etc...) so they can control sprites remotelly.

I have changed your program, to make an experiement, but I realized that when I send commands to remote micro:bit, looks that Scratch broadcasts it several times - not sure if exist and effective way for debounce it, I have used wait in Scratch, but not sure if there is a collateral effect.

What I did was:
Got file s2mb.py
Included:

import radio
import random
radio.on()

replaced display.scroll(str(cmd_list[1]), wait=False) to radio.send(cmd_list[1]) so I could use your scroll command to send any code via radio using and existent block).

The receiver micro:bit I flashed with the following code:

import radio
import random
from  microbit import display

radio.on()
while True:

    incoming = radio.receive()
    if incoming == 'a':
        display.scroll("a")
    if incoming == 'b':
        display.scroll("b")
    if incoming == 'c':
        display.scroll("c")

At the Scratch side I have used:

I think Scratch sending to remote micro:bit should be possible (at least worked), but I have no idea on the other way around (which makes the thing much better) and also if is possible to define a radio signal in order to avoid send the same commmand to all micro:bit.

Thanks!

Hi Alan,
I realized that after last update the analog and digital pins are not sending data to microbit - at least for me.
If I switch the file s2mb.py from 07 December 2017 (the first version I got), the microbit receives data in a properly way.
Please find enclosed the version that is working for me and the current one that doesn't - same I got in Github

I am testing with an LDR: (but connected to a microbit - of course ;o)

P.S Looks that the pip installer cames with s2mb2.py which is not avalaible from Github

s2mb_not_working.zip
s2mb_working.zip

"Shaken?" block does not give "true" even if micro:bit is shaken.

This is a similar problem to issue #17.

Hi, @MrYsLab I just send an update from pt-br transalation.
I realized that I forgot to translate one block - Value instead of Valor.

I´d appreciate if you can update it in future realeases.

Thanks

I've just installed s2m for the first time and when I type s2m in the cmd window, Scratch opens but there are no Microbit related blocks in the 'more block section. I have a Microbit connected and I don't see any errors when trying to launch s2m:

I installed everything following the directions here:
https://mryslab.github.io/s2m/usage/#starting-s2m-on-windows-mac-and-linux
I'm running windows 10.

I followed the user guide, but can't detect device either by autodetecting or specifying serial port.
After modifying serial port detecting part in s2m.py, I can detect device either by autodetecting or specifying serial port now.

Original code:

# if no com port was specified, try doing auto discover.
if com_port is None:
    print('Autodetecting serial port. Please wait...')
    if sys.platform.startswith('darwin'):
        locations = glob.glob('/dev/tty.[usb*]*')
        locations = glob.glob('/dev/tty.[wchusb*]*') + locations
        locations.append('end')
        # for everyone else, here is a list of possible ports
    else:
        locations = ['dev/ttyACM0', '/dev/ttyACM0', '/dev/ttyACM1',
                        '/dev/ttyACM2', '/dev/ttyACM3', '/dev/ttyACM4',

s2m has English UI only.
It would be great if it supports other languages. Localization support would be mandatory if students in elementary school wants to use s2m.

You can switch the block UI based on browser language.

Here is the code of an ScratchX extension that I created.
I think you can use similar logic.

https://github.com/champierre/scratch2mip/blob/master/scratch2mip.js#L32

Let me know if you need help for Japanese translation.

Hey @MrYsLab
It seems that the HTTP extension method will no longer be available in Scratch 3.0 that is supposed to be released by August 2018.
Do you have any plan to update your code to make it compatible with Scratch 3.0 javascript extensions?
Thanks!

Why do "pressed", "right", "left", "up", "down" in the s2m blocks for English begin with lower case letter?

I am getting below exception when executing s2m.

I am opening this issue to help expose it in case anyone else is seeing similar problems and want to add to the conversation.

Thanks for ur help first
I have a old project ,and I want to improve it by micro:bit
Have some methods to connect extension?(I can only connect by a new project)
Hope that you know what I said thanks!

Change the block from 3 drop-down menus to explicit numerical values. This will allow the user to control the parameters with variables.

I think I properly followed the installation guide https://mryslab.github.io/s2m/install/.
When I started "s2m", I got "Cannot locate s2m files on path." as below.
What could it be wrong?

I use MacOS Sierra 10.12.6(16G29).

Hi Alan, not sure if I have to use this channel to give a suggestion....sorry in case not.

I would like to suggest you to change the server port of file s2m_http_server.py from 50209 to 50210.
That will be nice in case a user want to combine extensions (Arduino and micro:bit).
So an Arduino can communicate to micro:bit via Scratch and vice versa.
I have changed my local file and worked fine for this purpose.
Thanks!

Hi, following a spanish version for motion project.
motion_es.zip

I have made a slight change in the spanish extension, changing the name from s2m to s2m-es, hope it's not an issue to suggest it as I was not the translator.

Thanks!

In some schools in Japan, they allow their students to use Scratch 1.4 only. Do you have a plan to support Scratch 1.4?
If yes, I can try and open PR.

I think I can use remote sensing protocol in a similar way I did in sctatch2mcpi(https://github.com/scratch2mcpi/scratch2mcpi).

In the attached project the communication Scratch-Microbit stops after a few minutes with much sound, e.g. buttons A and B does not work, and the LEDs does not update. The Scratch-project continues to run and updates the screen. There is no error message in the Command Prompt. You should not uncompress the zip-file, just rename it so that .zip is removed, since sb2-files are actually zip-files, but GitHub does not recognize this w/o the zip extension.
s2m-loudness.sb2.zip

The communication hangs faster if video in Scratch is switched on.

I think communication last longer if I e.g. change "wait 0 secs" in the forever-loop to e.g. "wait 0.2 secs".

A suggestion is, if possible, to output a message in s2m console that the communication with the micro:bit is broken.

It works again if I stop with Ctrl+C and then restart s2m.

I use a trial version of Windows that came out after Windows FCU. It's the latest in Slow Ring.

I want to turn on an led, but when I click the "Digital Write pin (0) value(0)"command, the led just flash and then turn off. I want to know if the led can be always on? Thanks a lot!

I am having trouble getting s2m to run on Windows 10. Followed install instructions with install of Python 3.7, the Mu editor but at command prompt 's2m', I get the error message 'Failed to detect serial port. Check cable or connection'. I have successfully installed and run s2m on a pi but want it on laptop for convenience but cannot get past this step. Microbit is attached to COM 1. Any help gratefully received.

try install https://scratch.mit.edu/help/studio/tips/howto/wedo2win-1/

but still cant connect.

look at this scratch2.0 never request(http://localhost:50209/poll).

Hi @MrYsLab, I have tested the following sketch:

I am using the last version of your program.
Eveerything works fine until I tilt the device.
In that moment the green circle became red.
looking to DOS it´s exactly the same as before.

How it works for you?

Thanks!
