Do you have plans to publish the extension and app to the Chrome Web Store?

It seems like this message pops up for every request (Ping, Discover, GET, ....).
I tried it on the eclipse coap site, coap.me and a localhost coap server

Is there somewhere a parameter value, that I have to change?

Hello,

I've noticed that the Copper Plugin for Chrome doesn't work with coap server which use IPv6. When i enter e.g. coap://[2000:620:190:ffff:300:4b00:66:1]:5683/ and i click on any command, i get the message "Error while sending: net::ERR_NAME_NOT_RESOLVED (-105)". The plugin for Mozilla Firefox on the other hand works fine. Is there a specific problem with chrome or are you working on that?

My name is Shaurya Doger and I am a student at IUPUI studying Computer Science. I noticed your GitHub webpage and I have almost downloaded the Cooper extension for my chrome but I seem to be running into the following errors. I will post the screen shots below. If I currently click on the copper extension from chrome, it does take me to page where I need to type my IP address but then throws me an error saying that app is not installed. As per one of my screenshots, both my app and extensions have been installed. Now, even though I have them, I am still confused as to why the error keeps occurring. I have tried both appID and extensionID into the “ClientPortChrome.js” but none of them work as they are still throwing me error “UNEXPECTED TOKEN” on step 4. Let me know soon if there are steps that can be taken to resolve this issue because I really need this working as I am trying to use raspberry pi with this for one of my class projects.

Regards,
Shaurya Doger

Hi everyone,

I have installed Copper4Cr following the Readme.md with the copy of appID in the JS file under extension, but an error occurred:

Some one solve this problem? Is this project under development or anyone can suggest another CoAP Client / User-Agent?
Thanks

I got appId "incnkikhjmmhligicpbaalagdmaeebaa" on chrome://extensions/ and is replaced the previous appId at extension/endpoint/ClientPortChrome.js according to step 4. Then I tried to access an example url at the very first popup and found a error as below.

URI:

coap://californium.eclipse.org/

Error:

This extension needs the Copper application to send Coap-Messages. Please install the app (Chrome Web Store) and reload.

Web store link:

web store link is https://chrome.google.com/webstore/detail/incnkikhjmmhligicpbaalagdmaeebaa

Any help or instructions?

NB: I think, no extention is available for "incnkikhjmmhligicpbaalagdmaeebaa". Firefox has removed copper extension for some security issues from their official extension list (I found this in a blog post).

Got stuck while performing COAP request in chrome.

Getting Error:
Error on performing CoAP request in Chrome - Error while sending: net::ERR_NAME_NOT_RESOLVED (-105)

Kindly help me regarding this issue:

Hello Everyone!

I'm facing one issue while trying to click on the Discover button. Below is the error.

Endpoint Error: Invocation of form sockets.udp.send(integer, binary, string, integer, string, function) doesn't match definition sockets.udp.send(integer socketId, binary data, string address, integer port, function callback)

I'm not sure whether it's is a genuine issue or I'm making some mistakes.

Manifest v2 extensions are being deprecated in 2023 in both Chrome and Edge, and so v2 manifest extensions (such as Copper) will soon stop working. (The latest version of Chrome might already be doing this.) Do you plan to move Copper to v3 manifests? Thanks!
