ai assistant stopped answering in just 1 conversation. all other sketchs converations are fine. but in just the 1 it thinks and you see the 3 dots bounce but the nothing. i have restarted, and rebooted pc, tried other browsers but still no joy. any help would be gratefully received.

Hi, @rcomfy
Welcome to the forum?

What does the AI problem have to do with Arduino?

Tom....

sorry i meant the Arduino AI assistant.

I moved your topic to an appropriate forum category @rcomfy.

In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Thank you I am fairly new to this.

Hi @rcomfy. Is the problematic sketch an Arduino Cloud IoT Thing sketch, or is it a normal non-Thing sketch?

rcomfy · January 31, 2026, 4:43pm

Hi its a cloud sketch

ptillisch · January 31, 2026, 4:51pm

Please post your full sketch.

I'll provide instructions you can follow to do that:

Open the sketch in Arduino Cloud Editor.
Click on the window that contains your sketch code.
Press the Ctrl+A keyboard shortcut (Command+A for macOS users).
This will select all the text.
Press the Ctrl+C keyboard shortcut (Command+C for macOS users).
This will copy the selected text to the clipboard.
Open a reply here on this forum topic by clicking the "Reply" button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.

Code block icon on toolbar390×118 4.25 KB
Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the copied code into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Repeat the above process if your sketch has multiple tabs.
Click the "Reply" button to publish the post.

They are my transmitter and receiver codes for a wireless dmx to go from the output of dmx signal for my pc to the lights without using a router. I am not sure if it is just a case of running out of free conversation with the Ai Assistant as I am on the free agreement etc

rcomfy · January 31, 2026, 5:08pm

i am almost there with it as i can connect with the lights and a a point was able to sent data from the trans to the receiver. and it seems to connect and receive to the pc dmx lead but will not receive the data in the trans serial when i change dmx values in the pc software. i know the dmx signal works as i plug the lead to the lights direct they respond how thy should and change when i change the values etc

Cool project!

Are you experiencing the problem with the Arduino AI Assistant when either of these sketches are open in Cloud Editor, or only when one of the two sketches is open?

It is a good hypothesis. Please click the following link to open the "Plan Usage" page in your web browser:

https://app.arduino.cc/plan-usage

Check the usage value on the "Editor AI assistant" line of the page. Does it show that you have used up the entire allowance of interactions provided by your Arduino Cloud plan?

rcomfy · January 31, 2026, 5:28pm

Hi thanks for that it is at the max Number of AI-assisted interactions available per month! do you know when they refresh is it at the start of a new month ie tomorrow or from when you first started using it?
