ESP8266, win7, Python 3.7.2. Everything works greatly, but I have these errors:

There aren't any errors in 's3e' and 'espgw - True' windows

I'd like to control the neopixel led, do you have any suggestions on how to build Scratch blocks?

Thanks

[MrYsLab]

Thanks for the detailed report. Does the problem occur from a power-up start of your computer, or does it run once, and then the error occurs when you stop the program and re-run it?

If you would like to learn how to create the blocks, I have four articles that describe the entire process. I based my work on this article that specifically deals with creating the blocks.

[MrYsLab]

I am closing this issue since I have not heard back from you. If you are still having issues, please add a comment here and I will see it. I can then reopen the issue if necessary. Thanks again for the report.

[libero62]

Sorry, the first of May in Italy is the national labor day, and I had no access to my computer at work.

I wish You opened again the issue Thank you very much From: Alan Yorinks Sent: Monday, May 03, 2021 2:19 PM To: MrYsLab/s3-extend Cc: libero62 ; Author Subject: Re: [MrYsLab/s3-extend] Some errors in 'backplane' and 'wsgw -i 9002' with esp8266, win7 (but everything works greatly (#27)

No problem.

<Does the problem occur from a power-up start of your computer, or does it run once, and then the error occurs when you stop the program and

The problem alwayis occurs, also after doing a clean rebot. I have got another issue:when I try to use Sonar (see the immage attached)it doesn't run and on the serial port I have the next output:

WebREPL daemon started on ws://0.0.0.0:8266 Started webrepl in normal mode turning led on ('0.0.0.0', 31337)

[MrYsLab]

Thanks for the information.

Other than the SONAR issue, does the crash happen randomly or does a specific Scratch block or a Scratch program cause the crash to occur?

Also, what version of MicroPython are you using? I want to make sure that when I test I am using the same version you are using.

Thanks.

[MrYsLab]

It looks like from your screenshot, MicroPython 1.8 is being used. That is a very old version. I tested with version 1.10, which is 2 years old, and the current version is 1.15. I will try upgrading my esp-8266 with 1.15, and I will see if the problem occurs. I am in the middle of another project, so it may take me several days to get to test this. Thanks.

[libero62]

I had tested it with Python 1.15 and have the same issue, then I have downgrade to Python 1.8 so your Installation And Usage Guide.

I thing that the problem can be in s3-extend installation on my pc. tomorrow I wish to try to uninstall Python on my pc then reinstall alwais, and report you the window command results. Thanks.

[MrYsLab]

Were you able to resolve the issue?

[libero62]

Unfortunately no, I reinstalled MicroPython esp8266-20210418-v1.15.bin on my NodeMCU ESP12 device, then reinstalled Python 3.7.2, Pip 21.1.1 and s3 extend on my windows pc without error. I have also tried the same installation on Mac Osx. I always have the same error.

[MrYsLab]

@libero62 I have tested here and am seeing some very strange behavior. If I run s3e, it does crash immediately, but if I run backplane, the esp gateway, and WebSocket gateway separately, it does not crash at all. When I originally tested, I had a much slower computer than I am using now, so I don't know if that may be the cause of the issues.

I too cannot get the HC-SR04 code to report. I am not sure yet what is going on, but what I am thinking of doing, is converting the server resident on the ESP8266 to use my Telemetrix library for the ESP8266. It is coded using the ESP8266 Arduino core, so it will be considerably faster than the MicroPython code and is simpler to install and update.

It will take a little time to convert to the new server. I will let you know when things are working.

[MrYsLab]

A quick update. I have re-tested my Python interface to the ESP-8266 that uses the Arduino-Core ESP8266 API. I have made changes to the ESP-8266 code and all seems to be working properly. So the next step is for me to modify the Gateway I created for the MicroPython version and adapt it for Telemetrix. I am hoping to have this completed and fully tested by the end of the week. I will post another update by the end of the week. Thanks for your patience.

[MrYsLab]

I have things working using Telemetrix. I have tested it on Windows 10 and it should also work on Windows 7. Other than loading the sketch from the Arduino IDE onto the ESP8266, you should not have to make any other changes.

I am going to remove the tone feature since Scratch does a much better job at creating tones and the tone library is dependent upon Arduino AVR timers.

I will be updating the documentation and hopefully, I will be able to release the code in the next several days.

[MrYsLab]

This is now fixed with the latest release. Installing the code for the ESP8266 is described here.

You did a great job. Now everything works very fine. Thank You.
