Hello,

many thanks for your IOTA related input and also for your very helpful and high quality content in general. I also appreciate all your videos!

However, concerning this tutorial, I have followed all mentioned steps and everything works fine until I am running mam_sensor.js in step 8. I think this could have maybe something to do with the node? I get the following Error in the console:

failed to attach message:
Error: Invalid Response: Error: getaddrinfo ENOTFOUND nodes.testnet.iota.org nodes.testnet.iota.org:443

Could you maybe provide a solution fot this? This would be great. I would appreciate any help.

Many thanks.

Kind regards

Sorry, I forgot my contact email concerning my previous question about the error message at step 8 when using the mam_snesor.js script.

Many thanks.

the content and source code of this are now out of date. For example the url is now https://nodes.devnet.iota.org:443

Would appreciate if you could update article to latest.

thanks

Hi,
meanwhile I think the URL has changed again to...
https://nodes.comnet.thetangle.org:443
Would it be possible to update the example on Windows 10 platform.
Even when changing Serial Port name to e.g. 'COM3' I receive the following message...
Error: Cannot find module 'serialport'
Thanks
Dirk
