Conn. problems with IMac UNO and ESP

snoopy2024 · March 20, 2025, 7:44pm

Hi in the cloud with things I tried to let the UNO board be recognized.
It failed even after all suggestions made during the errors.
Secondly this also happened with ESP8266 V3 boards.

If I run the IDE2.3.4 I can program the UNO.
For ESP8266 V3 the provided location link for additional board manager link is not working. http://arduino.esp8266.com/stable/package_esp8266com_jason.index

Hi @snoopy2024.

I'm not sure I understood correctly what you mean by this. Please provide a more detailed description of what you mean by this in a reply on this forum thread to help us to understand it.

Make sure to include the following information:

What did you do?
What were the results you expected from doing that thing?
What were the results you observed that did not match your expectations?

Make sure to include the full and exact text of any error or warning messages you might have encountered.

That is because it is wrong. You must use the URL provided in the official documentation here:

https://github.com/esp8266/arduino#installing-with-boards-manager

Make sure to copy the URL they provide in the documentation exactly.

Dear Sir,
Thank you for coming back so soon.
You are right it was a bit short written, but I am happy to tell that the link that you provided is working.

Make sure to include the following information: Herewith my info:

What did you do?
Made connection to the cloud with my Mac mini with MacOS Sequoia 15.3.2
I started with Cloud project and basically I copied the DHT11 project from Drubasaha than followed the steps correctly and put the secret key in the sketch. Runned the sketch >> Done Verifying Temperature_Control_mar19a a
What were the results you expected from doing that thing?
That load would take place to the board without errors.

You mention errors, but you haven't described any errors. The only thing you described is the "Done Verifying Temperature_Control_mar19a" notification that indicates the compilation was successful.

If you are encountering errors, then you need to provide a detailed description of those errors.

Maybe you attempted to attach a file named cloud.rtf to your message? If so, it failed.

PLEASE DO NOT EVER REPLY TO EMAILS FROM ARDUINO FORUM!!! You must instead come to the forum website and reply via the website interface. This is the only way to make sure that you will effectively communicate with us here on the forum.

Please also always avoid using file attachments if possible. Unnecessary use of attachments is inconsiderate to the forum helpers as it is less convenient for us to have to download a file and open it just to see what it contains so we can assist you. It also makes it less likely that you will get effective assistance as some forum helpers can't or won't download files.

It was somewhat reasonable to attach a ZIP file of your sketch in this case since the sketch contains multiple files. However, it is very rarely reasonable to post any other text content as a file attachment. You should instead paste it directly into your post.

The only exception is when the forum shows you an error that says the post is longer than allowed. In that case you can use an attachment. However, in that case you must use a basic txt file, NOT some inappropriate format like RTF. If you don't already have a real text editor application, then you need to install one as this is an essential tool for anyone writing code. I can recommend the excellent VS Code, but there are many other excellent free open source text editors so feel free to use whichever one you prefer.
